El Hierro volcano update: new pulse of volcanic tremor near La Restinga ?

What looks like a new swarm of earthquakes accompanied by strong harmonic tremor appeared on the southernmost seismic station at La Restinga. If it is not due to some local, human-induced work or malfunction, it suggests that the quakes are very shallow, since they don't appear on the signals of other stations.

Whatever is happening there will probably become clearer soon.

The latest earthquake swarm in the NE part of the island had more or less stopped during the past 24 hours. Some GPS stations showed 2-4 cm uplift during the weekend, which supports the idea of a new deep magma intrusion.

Volcanic activity worldwide 18 Mar 2014: Etna, Santa María / Santiaguito, Fuego, Karymsky, Dukono, ...

Tuesday Mar 18, 2014 18:32 PM |

Glow from weak strombolian activity at Etna's NSEC

Sinabung volcano yesterday (steam indicates hot areas on the lava lobe)

Strombolian eruption from Fuego last night

Etna (Sicily, Italy): There have been no significant changes in activity. Mild strombolian explosions continue at the summit vent of the New Southeast Crater (NSEC) and lava emission continues to feed flows from the effusive vents at the eastern side of the cone.

Karymsky (Kamchatka): Intermittent strombolian to vulcanian explosions continue at the volcano. This morning, VAAC Tokyo reported an ash plume at 7,000 ft (2.1 km) altitude extending SE from Karymsky.

Sinabung (Sumatra, Indonesia): The volcano continues to be active with no significant changes, but an overall decreasing trend. Lava effusion feeds the viscous lava extrusion lobe on its southern flank, which has been mainly growing on its eastern side.

No significant pyroclastic flows have occurred recently, only frequent smaller rockfalls. Small ash plumes continue to be regularly visible on satellite imagery.

The most recent report by VSI shows that seismicity has decreased overall. Hybrid earthquakes, indicators of rock fracturing by magma moving into the system, have disappeared. This suggests that pressure and magma supply rate have dropped a lot and that the eruption could be ending in a near future.

Dukono (Halmahera): Intense explosive activity, probably strombolian-type, continue at the volcano. Darwin VAAC reports ash plumes at 8,000 ft (2.4 km) altitude extending 80 nautical miles to the SW.

Kilauea (Hawai'i): (17 Mar) Lava lake at Kilauea summit remains stable at a high point of 37m (124ft) and despite rainy and windy conditions over the weekend, the summit glow viewing is still clear and as bright as ever from the Jaggar Museum.

Santa María / Santiaguito (Guatemala): Activity remains essentially unchanged. Viscous lava flows are active on the E and SW sides of the Caliente dome.

INSIVUMEH warns against the potential of hot lahars that the current and expected heavy rainfalls could trigger, re-mobilizing loose pyroclastic material that has been accumulating at the feet of the dome. The draining riverbeds of Nima I, Nima II, Samala, and San Isidro are the areas most at risk.

Fuego (Guatemala): Strombolian activity at the volcano has decreased a bit. Weak to moderate explosions occur at irregular intervals typically in the range of 1 hour, eject abundant incandescent lava to 100-150 m above the crater and generate avalanches on the upper slopes. The lava flow has stopped being active.

 

 

 

 

 

 

 

 

 

 

 

Slamet volcano (Java, Indonesia): strombolian activity in summit crater
Wednesday Mar 19, 2014 10:37 AM | BY: T
Posted Image
Strombolian activity at Slamet volcano a few days ago

Mild strombolian activity occurs from the summit crater of Java's second highest volcano.

Our correspondent Andi just returned from a visit: "... Mt Slamet which showing more activity with mild explosions. I did not see the lava dome or any glowing visually, because the mild strombolian just very deep and too slow ejected from its vent. Currently the climbing is closed and the level alert still in level 2. Explosion also can be seen from the village of Blambangan, Purbalingga."

Recent Kilauea Status Reports, Updates, and Information Releases HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE Wednesday, March 19, 2014 7:59 AM HST (Wednesday, March 19, 2014 17:59 UTC)

This report on the status of Kilauea volcanic activity, in addition to maps, photos, and Webcam images (available at http://hvo.wr.usgs.gov/activity/kilaueastatus.php), was prepared by the USGS Hawaiian Volcano Observatory (HVO). All times are Hawai`i Standard Time.

KILAUEA VOLCANO (CAVW #332010)

19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)

Current Volcano Alert Level: WATCH

Current Aviation Color Code: ORANGE

Activity Summary: The eruption continued at the summit and within the east rift zone. The summit tiltmeter network recorded continued DI deflationary tilt and the summit lava-lake continued to drop. At the middle east rift zone, the Pu`u `O`o vent continued feeding the Kahauale`a 2 lava flow whose distal end remained active and advancing very slowly to the northeast while burning forest. Gas emissions remained elevated.

Recent Observations at Kilauea summit: On this sixth anniversary of the summit eruption, the summit tiltmeters recorded continuing DI deflationary tilt (about -1.7 microradians over the past 30 hrs) and the lava-lake level continued to drop to a measured 58 m (190 ft) below the floor of Halema`uma`u crater. Gas emissions continued to be elevated: during the week of 01/01-01/07, the summit SO2 emission rate varied between 3,300 and 5,800 tonnes/day (see caveat below); however, no reliable emission rate measurements could be made over the past several months due to the persistent absence of moderate trade-winds except for a few brief periods during which the emission rates were measured at values within the range of 1,000 to 6,000 t/d (representing conditions of no spattering to spattering lake conditions). Regardless of wind direction, the plume includes a small amount of ash-sized tephra (mostly fresh spatter bits and Pele's hair from the circulating lava lake) that is deposited onto nearby surfaces.

Seismic tremor levels were low with several dropouts. Twenty-five earthquakes were strong enough to be located beneath Kilauea Volcano in the past 24 hours: 19 scattered on south flank faults, 3 beneath Halema`uma`u crater, and the rest within the rift zones. GPS receivers spanning the summit caldera recorded changes mimicking the recent tilt changes after recording about 3 cm of extension since early December, 2013; the long-term, cross-caldera measurements indicate continued extension at a rate averaging 10 cm/yr (4 in/yr) since March, 2010.

Background: The summit lava lake is within a nearly-cylindrical vent cavity with a diameter of ~160 m (520 ft) and nearly vertical sides inset within the east wall and floor of Halema`uma`u Crater. Its level has varied from about 25 m to more than 200 m (out of sight) below the floor of Halema`uma`u Crater. The vent has been mostly active since opening with a small explosive event on March 19, 2008. The surface level of the lava lake has remained mostly below the inner ledge (~31 m or 100 ft below the floor of Halema`uma`u Crater on October 29, 2012) and has risen above and flooded the ledge in October 2012 and January 2013 before receding to greater depths. The lake level responds to summit tilt changes with the lake generally receding during deflation and rising during inflation.

Recent Observations at the middle east rift zone vents: The tiltmeter at Pu`u `O`o cone recorded the start of DI deflationary tilt at 5 am yesterday (about 5 hrs after deflationary tilt started at the summit). The most recent sulfur-dioxide emission-rate measurement was 300 tonnes per day on January 29, 2014, from all east rift zone sources; emission rates typically ranged between 150 and 450 t/d since July 2012. GPS receivers on the north rim and south flank of Pu`u `O`o cone recorded fluctuations mimicking the tilt changes while also recording about 3 cm of extension over the past 3 months. The Pu`u `O`o eruption continued with no significant changes. Spatter cones on the floor of Pu`u `O`o crater displayed persistent glow with an open lava pond within the collapsed northeast spatter cone (see images and video); lava remained high in the northeast lava pond and periodically spilled over the east rim overnight.

Recent Observations of the Kahauale`a 2 flow: The northeast spatter cone complex continued to feed the Kahauale`a 2 lava flow. A satellite image acquired on March 16th showed that the most distant active breakout was still 8.0 km (5.0 mi) northeast from Pu`u `O`o; this is the farthest advance of the Kahauale`a 2 lava flow since mid-January when the flow extended 7.8 km (4.8 mi) northeast of Pu`u `O`o before stalling. The PNcam showed several clear views of burning forest and nighttime activity at the flow front through this morning.

In general, this slow-moving lava flow has made erratic progress over the past few months. Disruption of the flow front has occurred during strong DI deflation events when the lava supply abruptly decreased causing the flow front to stagnate. DI inflation and resumption of lava supply usually follow a few days later. Breakouts reappear well behind the stalled flow front and take some time to reach the front again. In this way, the flow front has not advanced more than 600 m (2,000 ft) since the first time it stalled in early November, 2013.

Background: The eruption in Kilauea's middle east rift zone started with a fissure eruption on January 3, 1983, and continued with few interruptions at Pu`u `O`o Cone, or temporarily from vents within a few kilometers to the east or west. A fissure eruption on the upper east flank of Pu`u `O`o Cone on Sept. 21, 2011, drained the lava lakes and fed a lava flow (Peace Day flow) that advanced southeast through the abandoned Royal Gardens subdivision to the ocean within Hawai`i Volcanoes National Park in early December 2011. The flows stalled and re-entered the ocean starting on November 24, 2012 until activity started to decline and the ocean entry ceased in August 20, 2013; the flow was dead by early November, 2013. The Kahauale`a flow, which started from the spatter cone/lava lake at the northeast edge of the Pu`u `O`o crater floor in mid-January, 2013, was dead by late April, but a new flow (informally called Kahauale`a 2) became active in the same general area in early May. In general, activity waxes with inflation and wanes with deflation.

Volcanoes Today, 20 Mar 2014: Colima, Slamet

Thursday Mar 20, 2014 13:00 PM |
Posted Image
Forcasted ash from Colima volcano (VAAC Washington)

Slamet (Central Java): (19 Mar) A stronger explosion Wednesday morning at 08:47 local time produced an ash column rising about 2 km, according to a local press article.

Light ash fall occurred in areas to the NW. The explosion was the largest in the current eruptive episode so far.

The alert status of the volcano (raised to 2 out of 4 last Monday) was not changed,- apparently, no significantly larger eruptions are expected. During the past days, the volcano has been producing strombolian eruptions at rates of 1-2 per hour, with ash plumes typically rising 500-1500 m.

Colima (Western Mexico): The volcano produced a series of small ash puffs last night (23:00 GMT). VAAC Washington alerted of low ash plumes beneath flight level 150 (15,000 ft / 4.5 km altitude) drifting east from the volcano.

Hekla volcano (Iceland): news & activity updates Hekla volcano (Iceland): eruption warning

Thursday Mar 20, 2014 18:08 PM | BY: T

Hekla volcano, calm this afternoon

The volcano has drawn media attention and is being closely monitored as it is believed it is "ready" for a new eruption (although there are no current indications that one is imminent).
A recent statement by Páll Einarsson, professor in geophysics at the University of Iceland, made headlines saying that "Hekla might eruption soon", because GPS deformation and strain measurements suggest that its shallow magma reservoirs have been filling up during the past years.
The volcano is notorious for having very little seismic precursory activity and only giving very short (tens of minutes to few hours) of warning immediately before an eruption occurs.
The last eruption was 14 years ago in March 2000. Authorities have put up warning tables for hikers and people approaching the volcano, and a text messaging system was implement as preparation for possible emergency situations should one find him/herself caught in the vicinity of the volcano should it erupt.

Volcano news: Poás volcano, Costa Rica Poás volcano (Costa Rica): new phreatic eruption
Thursday Mar 20, 2014 17:52 PM | BY: T
Posted Image
Phreatic explosion at Poàs volcano yesterday morning (Ovsicori webcam)

Another moderately sized phreatic eruption from the crater lake of the volcano took place yesterday morning at 07:08 local time.
The explosion ejected steam, water, mud and rocks to about 100 m height.
According to Ovsicori, this type of intermittent, sporadic explosive activity has been characterizing the volcano's typical behavior since 2006. Similar eruptions can be expected in the coming days or even months.
The so-called phreatic explosions themselves are caused by overheated fluids in the hydrothermal system beneath the lake, not directly by fresh magma, but can be very dangerous for anyone near when they occur.

Copahue volcano (Chile): alert level raised to orange

Friday Mar 21, 2014 18:58 PM | BY: T
Posted Image
Copahue volcano, quiet at the surface, today (SERNAGEOMIN webcam)

SERNAGEOMIN raised the alert level of the volcano to orange yesterday after an increase in seismic activity. A pulse of volcanic tremor was detected that could indicate magma moving into the volcano's plumbing system.

On the surface, no unusual activity has been seen at the volcano so far, except that an increase in SO2 emissions (approx 2,300 tons / day) was measured. This supports the idea that magma has risen under the edifice.

Whether this activity is followed by new eruptive activity remains to be seen. In most cases, intrusions of magma under volcanoes do never reach the surface, i.e. produce eruptions.

ONEMI (Civil Defense) published a bulletin stating that civil alert remains at yellow for the highest risk areas, in particular the most proximal areas around the volcano itself, but also include the city of Alto Biobío located 40 km west of the volcano, because it is at the mouth of a valley that drains Copahue on the north side and therefore, a potential pathway for mud flows that could occur during an eruption.

Recent Observations at Kilauea summit: The summit tiltmeters recorded continuing weak DI inflationary tilt and the lava-lake rose slightly to an estimated 46-47 m (151-155 ft) below the floor of Halema`uma`u crater by this morning. Gas emissions continued to be elevated: during the week of 03/13-03/19, the summit SO2 emission rate varied between 2,000 and 6,300 tonnes/day (see caveat below). Regardless of wind direction, the plume typically includes a small amount of ash-sized tephra (mostly fresh spatter bits and Pele's hair from the circulating lava lake); the heaviest pieces are deposited onto nearby surfaces while the finer bits can be carried several kilometers before dropping out of the plume.

Seismic tremor levels were low with several dropouts. Twenty-one earthquakes were strong enough to be located beneath Kilauea Volcano in the past 24 hours: 4 scattered on south flank faults, 11 (including 4 deep quakes) within the upper east rift zone and Koa`e Fault system, and the rest scattered south of the summit and in the middle and lower east rift zone. GPS receivers spanning the summit caldera recorded changes mimicking the recent tilt changes after recording about 3 cm of extension since early December, 2013; the long-term, cross-caldera measurements indicate continued extension at a rate averaging 10 cm/yr (4 in/yr) since March, 2010.

volcanoes Today, 24 Mar 2014: Karymsky, Dukono

Monday Mar 24, 2014 10:00 AM |

Karymsky (Kamchatka): A volcanic ash plume was see on satellite imagery this morning at 10,000 ft (3 km) altitude and extending SE of the volcano, VAAC Tokyo reported.

The volcano has been in a state of persistent, intermittent mild to moderate explosive activity at least since 1996.

Dukono (Halmahera): The volcano remains in elevated activity. Some of the (strombolian to vulcanian-type) explosions are strong enough to produce ash plumes spotted on satellite data. Yesterday evening and this morning, an ash plume could be seen drifting 50 nautical miles to the east.

An eruption from Fuego volcano this morning (INSIVUMEH)

Strombolian explosions remain relatively frequent (6-8 per hour) and some of them have been at the higher end of the typical normal activity scale, with ash plumes rising up to 1,200 m above the crater. Incandescent material falling back from the stronger explosions cause spectacular incandescent avalanches on the upper cone.

Moderately strong shock waves rattled windows in villages Panimache, Morelia, Sta. Sofía, and Panimache II. Loud degassing noises resembling jet-engines accompany the explosions.

KILAUEA VOLCANO (CAVW #332010)

19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)

Current Volcano Alert Level: WATCH

Current Aviation Color Code: ORANGE

Activity Summary: The eruption continued at the summit and within the east rift zone. The summit tiltmeter network recorded very weak inflationary tilt and the summit lava-lake rose slightly. At the middle east rift zone, the Pu`u `O`o vent continued feeding the Kahauale`a 2 lava flow whose distal end remained active and advancing very slowly to the northeast while burning forest. Gas emissions remained elevated.

Recent Observations at Kilauea summit: The summit tiltmeters recorded very weak inflationary tilt and the lava-lake rose slightly a measured 45 m (148 ft) below the floor of Halema`uma`u crater. Gas emissions continued to be elevated: during the week of 03/13-03/19, the summit SO2 emission rate varied between 2,000 and 6,300 tonnes/day (see caveat below). Regardless of wind direction, the plume typically includes a small amount of ash-sized tephra (mostly fresh spatter bits and Pele's hair from the circulating lava lake); the heaviest pieces are deposited onto nearby surfaces while the finer bits can be carried several kilometers before dropping out of the plume.

Seismic tremor levels were low with one dropout overnight. Twenty-one earthquakes were strong enough to be located beneath Kilauea Volcano in the past 24 hours: 5 scattered on south flank faults, 1 more deep quake beneath the northern section of Fern Forest Estates subdivision, and the rest scattered beneath the southern portion of the summit area. GPS receivers spanning the summit caldera recorded changes mimicking the recent tilt changes after recording about 3 cm of extension since early December, 2013; the long-term, cross-caldera measurements indicate continued extension at a rate averaging 10 cm/yr (4 in/yr) since March, 2010.

Background: The summit lava lake is within a nearly-cylindrical vent cavity with a diameter of ~160 m (520 ft) and nearly vertical sides inset within the east wall and floor of Halema`uma`u Crater. Its level has varied from about 25 m to more than 200 m (out of sight) below the floor of Halema`uma`u Crater. The vent has been mostly active since opening with a small explosive event on March 19, 2008. The surface level of the lava lake has remained mostly below the inner ledge (~31 m or 100 ft below the floor of Halema`uma`u Crater on October 29, 2012) and has risen above and flooded the ledge in October 2012 and January 2013 before receding to greater depths. The lake level responds to summit tilt changes with the lake generally receding during deflation and rising during inflation.

Recent Observations at the middle east rift zone vents: The tiltmeter at Pu`u `O`o cone recorded minor fluctuations. The most recent sulfur-dioxide emission-rate measurement was 200 tonnes per day on March 13, 2014, from all east rift zone sources; emission rates typically ranged between 150 and 450 t/d since July 2012. GPS receivers on the north rim and south flank of Pu`u `O`o cone recorded fluctuations mimicking the tilt changes while also recording about 3 cm of extension over the past 3 months. The Pu`u `O`o eruption continued with no significant changes. Spatter cones on the floor of Pu`u `O`o crater displayed persistent glow with an open lava pond within the collapsed northeast spatter cone (see images and video).

Recent Observations of the Kahauale`a 2 flow: The northeast spatter cone complex continued to feed the Kahauale`a 2 lava flow. On March 21st, HVO geologists mapped the most distant active breakout at 8.2 km (5.1 mi) northeast from Pu`u `O`o; this is the farthest advance of the Kahauale`a 2 lava flow since mid-January when the flow extended 7.8 km (4.8 mi) northeast of Pu`u `O`o before stalling. PNcam images show several clear views of smoke plumes from forest fires during the day and glowing spots at night confirming that the flow remained active.

In general, this slow-moving lava flow has made erratic progress over the past few months. Disruption of the flow front has occurred during strong DI deflation events when the lava supply abruptly decreased causing the flow front to stagnate. DI inflation and resumption of lava supply usually follow a few days later. Breakouts reappear well behind the stalled flow front and take some time to reach the front again. In this way, the flow front has not advanced more than 1.2 km (0.75 mi) since the first time it stalled in early November, 2013.

Background: The eruption in Kilauea's middle east rift zone started with a fissure eruption on January 3, 1983, and continued with few interruptions at Pu`u `O`o Cone, or temporarily from vents within a few kilometers to the east or west. A fissure eruption on the upper east flank of Pu`u `O`o Cone on Sept. 21, 2011, drained the lava lakes and fed a lava flow (Peace Day flow) that advanced southeast through the abandoned Royal Gardens subdivision to the ocean within Hawai`i Volcanoes National Park in early December 2011. The flows stalled and re-entered the ocean starting on November 24, 2012 until activity started to decline and the ocean entry ceased in August 20, 2013; the flow was dead by early November, 2013. The Kahauale`a flow, which started from the spatter cone/lava lake at the northeast edge of the Pu`u `O`o crater floor in mid-January, 2013, was dead by late April, but a new flow (informally called Kahauale`a 2) became active in the same general area in early May. In general, activity waxes with inflation and wanes with deflation.

Hazard Summary: East rift vents and flow field - the Kahauale`a 2 flow does not pose any immediate threat to residential areas; near-vent areas could erupt or collapse without warning with spatter and/or ash being wafted within the gas plume; potentially-lethal concentrations of sulfur dioxide gas may be present within 1 km downwind of vent areas. Active lava flows within forest can produce methane blasts that propel rocks and other debris into the air. All recently active lava flows are within Hawai`i Volcanoes National Park and adjacent State land managed by the Department of Land and Natural Resources or the Office of Hawaiian Affairs. Kilauea Crater - ash and Pele's hair can be carried several kilometers downwind; potentially-lethal concentrations of sulfur dioxide can be present within 1 km downwind.

Slamet (Central Java): Strombolian explosions of generally small size continue at irregular intervals.
According to our correspondent Oystein, who visited the volcano last weekend, "the eruptions observed were fairly small (strombolian activity) and the interval between the eruptions ranged from 30min to 3 hours, during the periods I had clear views and were able to observe. No booming noises could be heard during the eruptions or incandescent material observed."

Fuego (Guatemala): The volcano's activity has increased, INSIVUMEH and CONRED reported. The number of explosions rose to 8-14 per hour over the past days and the strongest ones produce ash plumes rising more than 1 km above the summit and drifted 12 km to westerly directions.
Seismic data also show an increase in tremor (internal vibration). INSIVUMEH thinks that a new lava flow and / or another paroxysmal phase at the volcano could occur soon.
The explosions at the volcano generated rumblings and shock waves that rattled ceilings and windows in villages Panimaché, Panimaché II, Morelia, Santa Sofia and others in the area at distances of more than 8 km.

Reventador volcano (Ecuador): new eruption

The volcano has entered a new eruptive phase since yesterday, Ecuador's Institute of Geophysics (IGP) reported. Starting from 15:00 local time yesterday, increasing tremor was registered and steady ash emissions were observed. At night, incandescent blocks could be seen and heard rolling down from the crater where probably a new lava dome has started to appear.
Small pyroclastic flows descended on the eastern, southeastern and southern flanks of the volcano, probably as a result of re-mobilization of fresh lava and tephra deposits. These so-called secondary pyroclastic flows reached lengths of 500 m below the summit.
IGP assumes the most likely scenario for the evolution of the new eruptive episode is that activity continues at similar levels for a while. So far, lava avalanches and pyroclastic flows have been confined within the caldera, near the flanks of the main cone. So far, no reports of ash falls became available from communities in the nearby areas, suggesting that the eruption is still small. An important hazard remains in the form of lahars (mud flows), which can be generated by re-mobilization of loose material during heavy rainfall and would most likely threaten the bed and banks of the Quijo river.

Glacial Flood in Grímsvötn Volcano By Zoë Robert March 26, 2014 10:37 Updated: March 26, 2014 10:38

A glacial outburst flood (jökulhlaup) has started in Grímsvötn volcano. According to measurements by the University of Iceland’s Institute of Earth Scientists, the water volume in Grímsvötn is similar to during the glacial outburst flood in November 2012, ruv.is reports. 

It is not considered likely that the flood will cover the road on Skeiðarársand or the bridge over Gígjukvísl river. The bridge was replaced when it was swept away during a huge glacial flood in 1996.

Volcanic activity worldwide 27 Mar 2014: Etna, Merapi, Marapi, Ubinas, Karkar, Dukono, Batu Tara

Etna (Sicily, Italy): During the night, the lava effusion and persistent mild explosive activity from the New SE crater ceased, after being nearly continuously active for over two months.

If this is a true end or only a short pause to the latest eruptive phase which on 22 January remains to be seen. The tremor fell back to low levels in correspondence.

Karkar (Northeast of New Guinea): Several ash plumes at estimated altitude of 8,000 ft (2.4 km) were spotted during the past 2 days. This suggests a new eruptive phase could have started at the remote volcano.

Batu Tara (Sunda Islands, Indonesia): After a relatively long time with no spotted ash clouds, an ash plume was seen yesterday again on satellite imagery (VAAC Darwin).

The remote volcano in the Fores Sea has been site of continuing strombolian activity since at least 2006. Some of the eruptions are strong enough to leave ash plumes that can be seen on satellite images.

Merapi (Central Java, Indonesia): A possibly strong eruption was reported from the volcano this afternoon (13:55 GMT). Satellite data showed an ash and SO2 plume drifting SW at estimated 32,000 ft (9 km) (VAAC Darwin). The plume is quickly dissipating, suggesting that the eruption was an isolated (possibly phreatic) explosion.

No other details are at the moment available.

Marapi (Western Sumatra, Indonesia): The volcano erupted again yesterday afternoon at 16:15 local time, the volcano observatory post reported. It appears it was one of the largest explosions during the volcano's current phase of activity.

Although the eruption was itself not visible due to cloud cover, the seismic signal showed a strong explosion that lasted 38 seconds and relatively "thick" ash fall occurred shortly afterwards in Batipuh and Tanahdatar districts until 17:45.

.

The alert level of Marapi remains unchanged at level II out of 4. Authorities recommend people to avoid a 3 km radius zone around the volcano.

Marapi has been in a phase of activity characterized by sporadic explosions of generally small size since 3 August 2011. Earlier eruptions this year, according to local press occurred as follows:

Dukono (Halmahera): Activity at the volcano continues to be intense. An ash plume was reported extending 80 nautical miles to the west at 10,000 ft (3 km) altitude this morning (VAAC Darwin).

Ubinas (Peru): The volcano's new lava dome continues to grow slowly within the crater. New field observations published yesterday in a detailed report showed that the lava dome is now approx. 120 m in diameter and has completely filled the inner pit left by the explosive activity in 2006 (as of 19 March). Visible glow (even in daylight) indicates very high temperatures.

No explosions have occurred since the vent-clearing explosion on 14 Feb, but the volcano emits a significant plume of steam, SO2 gas and sometimes dilute ash. On 21 and 23 March, the steam-gas-ash plume rose 1800 m above the crater.

On 25 March, light ash falls were reported in the towns of Querapi and Ubinas, as well as strong rumbling noises in distances up to 6 km SE.

Seismicity remains above background with frequent earthquake swarms related to internal fluid movements.
