KÄ«lauea volcano eruption update

Lava advances within 1km of farms

Update Thu 04 Sep 03:50

According to officials, the June 27th lava flow has reemerged for the second time from a huge ground crack along Kilauea's east rift zone, this time approximately 13.2 km (8.2 miles) from the vent and 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna Forest Reserve, but still continues moving through the ground crack to within 1.1 km (0.7 miles) from the boundary.

The inhabited area under immediate threat, Kaohe Homesteads, consists mainly of farms who are already relocating cows, horses, goats & sheep due to increased emissions and smoke from burning forest. The Civil Defense plans to issue an evacuation notice 5 days before lava is expected to hit the community, but with natural variability there will be some guesswork involved. The Hawaiian Volcano Observatory plans to increase the alert level from a "watch" to "warning" status within the next day or so, which will trigger Civil Defense to close the area to all non-residents. Looking ahead, the town of Pahoa and the main highway into the lower Puna district could be under threat next, and authorities are already considering construction on alternate routes should this look likely to happen.

Will lava advance through Kaohe and/or Pahoa? In the short term, probably not. Once the lava establishes a good downhill path out of the cracks, it will advance to the northeast because of the slope, and if it can establish that path from the current spillover point it will miss Kaohe. However, in the longer term (however long Pu`u `O`o continues to feed lava in this direction, which could be weeks to years), the big cracks will continue to funnel lava closer to Kaohe and Pahoa and likely create multiple spillover points. The longer the eruption continues without a plumbing change, the more likely lava will fill in the whole area.

We will issue updates as frequently as necessary, reporting directly from Kilauea on the developing situation with specialized coverage.

KÄ«lauea volcano eruption update

Lava advances parallel to farms

Update Sat 06 Sep 05:54

Lava flows continue to advance downhill through the jungle on a path that will miss Kaohe Homesteads, having first entered and overtopped several large ground cracks on Kilauea volcano's east rift zone. The farthest lava front is now 13.3 km (8.3 miles) from the vent and 1.2 km (0.7 miles) from the east boundary of the Wao Kele o Puna Forest Reserve, and moving northeast parallel to the boundary.

The latest map issued shows 3 large flows moving away from the cracks, whose path will take them downhill parallel to the Forest Reserve boundary and the threatened community of Kaohe Homesteads. Issued maps for the first time have blue lines indicating probably flow direction based on topography, showing that without any major changes the current flow will advance around Kaohe and if it continues long enough, cross the highway just north of Pahoa.

The question still remains whether these spill-overs can take the whole volume of lava erupted by the volcano, or whether lava finds its way into other large cracks which can funnel it closer to the inhabited zone. After that, the major question is how long the pipeline feeding the flow can remain stable. Will it be just one more month like the Kahaualea 1 flow ending in April 2013, or a full year like the Kahaualea 2 flow which ended in June 2014? For now, the closest communities are still safe but the highway appears under threat and there are other communities beyond.

Within the last 24 hours, the Volcano Observatory has upgraded Kilauea's status from a watch to a warning, Civil Defense has closed the threatened neighborhood to non-residents, the Mayor has declared a state of emergency, and most recently the Governor has issued an emergency proclamation, setting the stage for possible evacuations and construction of an alternate route into the district should the highway be cut off by lava. The warnings indicate that authorities believe lava may enter the community within 5 to 7 days, but that will be a conservative guess and for now the lava flow continues to flow parallel, but away from the community through undeveloped land.

There has been media coverage over the lava diversion debate: can and should the authorities divert the lava flow? In today's world of liability, it'll never happen. But if you're a resident downhill from the lava, you might be inclined to ask anyways... and you would be reprimanded by other locals who see the lava as an extension of the goddess Pele. Perhaps the real story there is that Hawaiian culture is alive and well!

We continue to keep our thoughts with the 30-40 residences under threat as we report on further developments.

Volcanoes Today, 9 Sep 2014: Bardarbunga volcano, Kilauea, Zhupanovsky, Stromboli, Ubinas

Tuesday Sep 09, 2014 09:00 AM |

Thermal images of the active lava flow on the Sciara and the crater area with small explosions (INGV Catania)

Lava fountains at the main fissure this morning (Mila webcam)

September 8, 2014 eruption map by USGS-HVO.

Steamning / ash venting from Ubinas yesterday

Stromboli (Eolian Islands, Italy): The lava effusion continues at reduced rate, feeding an active flow on the upper part of the Sciara del Fuoco west of the previous main flow.

Small explosive events continue to occur from the summit vents.

Bardarbunga (Iceland): The fissure eruption at Holuhraun continues, although it appears that only the main fissure is still producing lava fountains and flows, while the smaller fissures south of it became inactive and only emitted steam yesterday.

The intensity of the eruption, i.e. the average output of lava, seems to be stable. Lava flows have been reaching the waters of Jökulsá á Fjöllum river, without producing explosive activity, only steam. The lava flows now cover almost 20 square km.

Earthquake activity has decreased at the intrusion, but continues at the caldera of Bardarbunga volcano, which has been subsiding.

Another swarm is in progress north of Herðubreið, an impressive tuya volcano in the midst of the Ódáðahraun desert close to Askja volcano.

Zhupanovsky (Kamchatka, Russia): Ash emissions from the volcano have increased. Yesterday morning, VAAC Tokyo reported ash plumes that rose to 8-11 km altitude and drifted south and were visible on satellite images.

Today, new, but smaller emissions were reported with plume heights of 3-4 km.

The aviation alert level was raised to orange. ~######~

Kilauea (Hawai'i): The latest updates from authorities show no significant change in the path of the lava flow, only advancement through the jungle away from houses, for now.

The flow has advanced relatively quickly covering roughly 1/2 mile (3/4 km) in the past 2 days, but typically that rate is hard to sustain for long. Between the six days of Aug 6-12, the map shows the flow made about 1 mi forward progress, but during the next six days the flow advanced only half that distance, totaling 1.5 mi (2 km) in 12 days.

If the flow follows the easiest downhill path (marked by the blue line crossing the red flow tip on the map), it has more or less 4.5 mi (6 km) to cover until it would reach Highway 130, fortunately with no houses on the way. If it follows a similar rate of advance as Aug 6-18, we can expect that will take about 1 month to threaten the closest infrastructure, or by early to middle of October.

Ubinas (Peru): Activity at the volcano has been low during the past weeks. Intense steaming and occasional small ash emissions have been reported. However, sudden larger explosions such as the one on 21 Aug, could still occur any time.

Steam plume and the lava flow (dark tongue) from Semeru this morning

The slow extrusion of a lava flow from the summit crater continues and forms a dark tongue extending a few 100 meters. Rockfalls detaching from it roll frequently down the Kembar ravine on the southern flank.

On contrast, the previously typical intermittent strombolian ash explosions of the volcano, in continuous activity since 1976, have been almost absent during the past months.

KÄ«lauea volcano eruption update

How lava flow projections are refined

Update Fri 12 Sep 23:33

HVO's latest update:
"The flow front [yesterday at 12:30pm] was 14.8 km (9.2 miles) from the vent, measured in a straight line, and 0.3 km (0.2 miles) from the Forest Reserve/Kaohe Homesteads boundary. The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 16.9 km (10.5 miles). Between September 6 and 10, the flow front advanced at approximately 400 meters (460 yards) per day. Between September 10 and 11 the advance rate dropped slightly to approximately 300 meters (330 yards) per day. The flow front is still in thick forest, creating smoke plumes as it engulfs trees and other vegetation, but fires are not spreading away from the flow."

The lava flow's turn to the northeast this week surprised many online observers, but was not as big a surprise to the scientists at HVO. The blue lines on HVO's flow update maps indicate the steepest downhill direction calculated from a digital elevation model obtained previously by satellite, but the satellite can't see the ground beneath the trees. These smaller hidden variations play a significant part in determining a lava flow's path, and in order to address that HVO scientists run simulations which introduce random variations of about 6 ft (2m) to the DEM surface. Then they compile a probability map based on those simulations. This technique was proven successful during a recent eruption of Mt. Etna, and is now collaboratively being used in Hawai'i. In fact, HVO's simulations earlier this week showed the current flow path as a good possibility given those random variations, but those maps have not been published online, only presented at the public community meetings.

volcanoes Today, 13 Sep 2014: Lokon-Empung volcano, Bardarbunga, Kilauea, Slamet

Saturday Sep 13, 2014 16:00 PM |

Ash emission from Lokon volcano this morning (VSI webcam)

Aerial photo by HVO of lava flow within 170m of Kaohe Homesteads.

Residents at the public lava flow meeting in Pahoa on September 11, 2014.

Bardarbunga (Iceland): The eruption continues at similar levels as during the previous days. IMO estimates the volume of lava erupted so far to be at least 200 million cu m, and the surface covered by it 24.5 square km. The lava flows continue to travel eastwards into Jökulsá á Fjöllum river.
At the caldera of Bárðarbunga, subsidence continues at a speed of more than half a meter per day.

"Gas cloud from the eruption drifts to the east. High level of SO2, sulphur dioxide, was measured at Reyðarfjörðyour last night around 10:00 o'clock. The highest value measured were just under 4000 micrograms per cubic meter. These are the highest values measured in Iceland. High level, 685 micrograms per cubic meter, was also measured in Egilsstaðir." (IMO)

Slamet (Central Java): Activity at the volcano has increased and VSI raised the alert level to "siaga", 3 on a scale of 1-4. The mild strombolian activity which had been going on for months at the volcano has become more and more intense since the beginning of September. Some explosions in the past days have been strong enough to eject incandescent material to all over the summit cone of the volcano.
In its latest report on 11 Sep, VSI mentions that 165 eruptions occurred on that day with ejection heights between 50-1500 m.

BNPB, Indonesian's Civil Protection began preparing for a possible evacuation. According to them, 23,699 people are located within a radius of 5 to 6 km from the summit, and the area up to 4 km radius around the volcano has been declared an exclusion zone.
56,000 dust masks have been distributed to the local population.
~####################################################

Lokon-Empung (North Sulawesi, Indonesia): Small ash emissions along with white steam plumes have occurred again from the volcano recently. At the moment, there is no indications that they have been caused by new magma near the surface, and could be phreatic in nature, or due to disturbance of the hydrothermal system.#######

Kilauea (Hawai'i): HVO issued the 4th warning status update tonight:
"Between September 10 and 12, the June 27th flow advanced north-northeastward at an average rate of 250 m/day (820 ft/day). By the afternoon of September 12, the flow had advanced approximately 14.9 km (9.3 miles) straight-line distance from the vent, or to within 170 m (560 ft) of the boundary between the Wao Kele o Puna Forest Reserve and the northwest corner of Kaohe Homesteads. At the average rate of advancement of 250 m/day (820 ft/day) since September 10, we project that lava could flow from its current location into the northwest part of Kaohe Homesteads within a day, and to the PÄhoa Village Road (government road) in PÄhoa within 20 days" if there are no major changes.

As seen in the photograph and maps accompanying HVO's newest release, the lava flow is now at the same elevation as the corner of Kaohe Homesteads, missing it by 170 m (560 ft) and expected to move away downhill. These uphill homes seem to have been spared for now, but as the flow travels further downhill it's likely to come closer to other houses, with the district of Puna's biggest village and highway looming 3.1mi (5.0km) below. For now, it's a tempered bit of good news.

...12 Sep:
HVO's latest update:
"The flow front [yesterday at 12:30pm] was 14.8 km (9.2 miles) from the vent, measured in a straight line, and 0.3 km (0.2 miles) from the Forest Reserve/Kaohe Homesteads boundary. The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 16.9 km (10.5 miles). Between September 6 and 10, the flow front advanced at approximately 400 meters (460 yards) per day. Between September 10 and 11 the advance rate dropped slightly to approximately 300 meters (330 yards) per day. The flow front is still in thick forest, creating smoke plumes as it engulfs trees and other vegetation, but fires are not spreading away from the flow."

The lava flow's turn to the northeast this week surprised many online observers, but was not as big a surprise to the scientists at HVO. The blue lines on HVO's flow update maps indicate the steepest downhill direction calculated from a digital elevation model obtained previously by satellite, but the satellite can't see the ground beneath the trees. These smaller hidden variations play a significant part in determining a lava flow's path, and in order to address that HVO scientists run simulations which introduce random variations of about 6 ft (2m) to the DEM surface. Then they compile a probability map based on those simulations. This technique was proven successful during a recent eruption of Mt. Etna, and is now collaboratively being used in Hawai'i. In fact, HVO's simulations earlier this week showed the current flow path as a good possibility given those random variations, but those maps have not been published online, only presented at the public community meetings.
The flow's speed has only decreased slightly as well, reflecting the steeper topographic slope of the area and giving the flow a long and narrow geometry. At present the flow width is reportedly 200-300m, which could restrict the lateral damage caused by the lava, at least in the short term. Looking ahead, the longer a lava tube system remains active, the more likely it will produce flows laterally, but for now there's no reason to believe the lava flow won't remain narrow as it builds downhill momentum towards the ocean. Along the same lines, there's no indication that the lava flow will slow down anytime soon and scientists now project it will cross the northern half of Pahoa and the highway around September 24-26.

...12 Sep:
At the public meeting held at Pahoa High & Intermediate School last night, officials presented the latest lava flow maps and projections following the flow's unexpected turn towards Pahoa town two days ago. HVO scientists reported that the steep slope has allowed to flow to continue moving quickly and that the new path puts it directly through the town of Pahoa in the range of 13-15 days.
Residents were offered the latest science, logistics concerning evacuation and possible disruption of services, and a prayer reminding that people's greatest resource is each other. Hawaii County Mayor Billy Kenoi drew the loudest applause when announcing that construction has already started on two alternate access roads into the area, but the mayor reminded residents that once the flow crosses the first highway it will continue downhill and eventually cut off these other, under construction routes as well. The mayor then announced plans to repave the Chain of Craters Road from within the National Park to Kalapana despite the great expense and lack of county funds, with the hope that assistance will come from the state or federal level. The county is going as far as scrapping construction on a children's playground in Pahoa in order to relocate those contracted workers to road construction.

The mayor also stated that lessons learned from Tropical Storm Iselle will be put to use, prioritizing uninterrupted power service, telecommunication and road access as the key components for all other concerns, including health care, postal service and bus service. The county is establishing a crisis center at the Pahoa Community Center within 72 hours and discontinuing public meetings, although an information fair is being held tomorrow to connect residents to service providers including banks, insurance, police, fire, water, power, moving & storage, health care, legal advice and transportation.

More than 12,000 people have been forcibly evacuated in the Philippines as seismologists raise alert over the potential eruption of archipelago's most active volcano. "We are now raising the alert status of Mayon Volcano from alert level 2 to 3," Renato Solidum, head of the Philippine Institute of Volcanology and Seismology (Phivolcs), said, as quoted by Reuters. The volcano is located in the central Albay province on the Luzon Island, and has erupted at least 48 times since 1616. "What the alert level 3 did was to fast-track the preparation to evacuate 12,000 families in the 6-8 km extended danger zone," Albay's Governor Joey Salceda said, adding that people will be provided with temporary shelters for up to three months, according to Reuters. The Philippines make the so-called Ring of Fire in the Pacific Ocean, an area subject to most of the world's eruptions.

Volcanoes Today, 17 Sep 2014: Stromboli volcano, Bardarbunga, Kilauea, Mayon

Wednesday Sep 17, 2014 20:00 PM |

Small explosion at Stromboli's NW summit vent

Hazard map of Mayon volcano with 6 km / 7 km (SE sector) exclusion zone (image: GVP)

Latest HVO image of advancing front near Kaohe Homesteads, September 15, 2014.                                            

Stromboli (Eolian Islands, Italy): Lava effusion continues with little changes overall. During the past weeks, the main lava flow has been traveling in the central part of the Sciara where it is mostly hidden from the webcam.

The main flow front almost reached the sea again last night and this morning, but stopped shortly before the shoreline.

Beneath the vent at 650 m elevation, occasional overflows occur to feed small secondary flows on the northern upper part. This was visible on the publicly available INGV webcam located at 400 m elevation.

At the summit itself, small explosions occur from time to time, producing small puffs of ash.

Bardarbunga (Iceland): The eruption at Holuhraun continues. According to the Icelandic Met Office, there are no signs of decreasing magma output. The lava flow field continues to spread.

At the Bárdarbunga caldera, subsidence of 50 cm / day continues. GPS measurements show irregular deformation patterns, but it is not completely clear what these mean except that the magma movements underground are probably changing their paths.

Seismic activity today and yesterday has been rather intensive, IMO wrote in its latest update:

Mayon (Luzon Island): The volcano could to be heading towards a new eruption. PHILVOLCS raised the alert level of the volcano was raised from 2 to 3 (on a scale of 1-5) on 15 Sep, following increased seismic activity and observation of small incandescent rockfalls on the southeastern upper flank.

The presence of low-frequency earthquakes suggests that magma has started to rise within the volcano, which would explain the recently observed lava dome and the glowing rockfalls during recent days, which in turn likely originated from it.

.

The exclusion zone around Mayon has been extended to 6 km around the whole volcano and 7 km on the most exposed southeastern sector. This area is most at risk, if dangerous pyroclastic flows (hot avalanches of fragmented lava from the dome, mixed with hot air and gasses) develop

Lava flow continues slow advance past closest homes

Update Wed 17 Sep 19:54

Pu'u 'O'o's "June 27th flow" continues to advance at a rate around 215m (705ft) per day through vacant forest, but has crossed the Forest Reserve boundary as it continues to skirt downhill of the nearest homes.

Yesterday the flow front was 3.3 km (2.1 miles) upslope from Apa`a Road, which hosts the densest cluster of homes in the flow's likely path. HVO's latest estimate projects "that lava could flow from its current location to Apa`a Rd in 15 days and to the PÄhoa Village Road (government road) in PÄhoa within 20 days" based on current advancement rate.

Officials on Wednesday announced the complete mandatory evacuation of 7,000 families or more than 35,000 individuals to get them out of harm's way in Albay province in the Bicol Region where Mayon Volcano, described as having the world's most perfect cone, continued to show signs of erupting. Albay Governor Joey Salceda also declared a state of calamity to enable the provincial government to use its calamity fund representing five per cent of its annual budget to assist the evacuees with relief goods like rice, canned goods and medicines. "The mandatory evacuation included the pets and livestock of the evacuees so they would no longer have a reason to sneak back to their homes," Salceda told GMA News. On Tuesday, 3,000 families or 15,000 people were initially evacuated from the permanent six-kilometre danger zone while evacuation of the remaining 4,000 families or 20,000 people residing from the extended seven-kilometre danger zone was completed on Wednesday, Salceda reported. He said he already ordered the provincial government's relief and medical teams to immediately attend to the urgent needs of the evacuees particularly to prevent the outbreak of diseases like colds, flu, fever and cholera that affect mostly children and the aged. Salceda also disclosed the imposition of a ban for safety reasons on activities around Mayon like trekking and the driving of all-terrain vehicles, which have drawn local and foreign visitors to the province annually. Instead, he said, visitors would be allowed to see the volcano from viewing decks far from the danger zone. The Philippine Institute of Volcanology and Seismology (Phivolcs), meanwhile, said Mayon on Wednesday continued to show signs of increased activity that could lead to lead to an eruption. The alert level remained at 3, Phivolcs said, meaning that magna was at the crater and that "hazardous eruption was possible within weeks." It added that in the past 24 hours, it recorded 45 volcanic earthquakes and 270 rockfalls through its seismic instruments installed around Mayor. Earlier, Phivolcs recommended the mandatory evacuation of residents around the volcano's permanent danger zone due to the dangers posed to their safety by rockfalls, landslides and sudden explosions.

KÄ«lauea volcano eruption update

Lava flow narrows, quickens towards Pahoa

Update Fri 19 Sep 10:22

Official releases from the Hawaiian Volcano Observatory over the past 48 hours indicate the lava flow is now advancing at a rate of 290m (960 ft) per day and has narrowed once again, after spreading out and slowing down for several days.

Accordingly, estimates of first impact have been revised, for Apa`a Rd around September 26 and for PÄhoa Village Road around September 30, but these are educated guesses and likely subject to further revisions. The main highway will likely be affected with one day of the main village road.

Work continues on alternate bypasses at a steady pace, with most residents of previously quiet neighborhoods graciously accepting the need to sacrifice their isolation to these new routes for the greater good. Locals are beginning to absorb the future impact of this lava flow on the island and making longer-term plans, describing "a disaster in slow-motion" which may produce refugees for the first time in modern Hawai`i.

Indonesia's Mount Slamet volcano began violently erupting Friday morning, scattering ash over surrounding villages in central Java. There are seven villages only four miles from the volcano. Officials have made preparations to move the nearly 24,000 residents in case the volcano becomes more dangerous. The eruptions started several days ago, but have grown increasingly violent. Java is Indonesia's main island. It includes the capital, Jakarta, and is home to more than half of the country's 240 million people.

Semeru (East Java, Indonesia): Our recent tour group on Java observed mild ongoing strombolian activity in the volcano's summit crater.

A flat lava dome is growing there and extruding a viscous lava flow into the open ravine to the south flank.

Colima (Western Mexico): The volcano's activity has picked up again recently. A new viscous lava flow has started to descend on the volcano's SW flank.

The lava flow is being formed as the cake-like lava dome overspills the rim of ths summit crater. Sometimes, it generates small incandescent avalanches.

Rincón de la Vieja (Costa Rica): The volcano increased its activity. Since 17 Sep, phreatic explosions have regularly occurred from the main crater which contains an acid lake. Although none was observed directly, at least 6 explosions could be identified by seismic signals. An aerial survey yesterday showed no fresh deposits, which suggests that the eruptions were rather small and did not eject material beyond the lake.

Park rangers have also observed that the volcano is currently having some increased activity: strong bubbling at the lake and floating sulfur rafts on the surface. The water temperature has increased significantly by 15 deg C., compared to measurements made in 2013.

.............................................########################################################.......................................................

The main hazard from the volcano at present would be hot, acid mud flows (lahars) if larger explosions cause the lake to drain or eject larger quantities of water. Such lahars could affect all sides of the volcano, but the areas to the NE around the Azul and Pénjamo river beds would be most at risk. During previous eruptions such in 1995, they had been affected by lahars already.
