Pause continues so it could well be all over folks

KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE

Kīlauea Volcano Lower East Rift Zone (LERZ)

A small lava pond remains in the Fissure 8 cone. Observations yesterday (August 9) show the pond to be largely crusted over with only minor areas of incandescence. Fissure 8, and the channel leading from Fissure 8, show no sign of reactivation. Fissures 9, 10, and 24 up-rift of Fissure 8, and the down-rift Fissures 13, 23, 3, 21 and 7 continue to steam, but are not incandescent. Lava is oozing at several points along the Kapoho Bay and Ahalanui coastline creating wispy laze plumes.

Although the lull in LERZ activity continues, it is common for eruptions to go through periods of diminished output, or to pause completely, only to return with renewed vigor days or weeks later, or longer. Resumption of the activity on the LERZ could occur at any time, and residents should remain informed and heed Hawaii County Civil Defense messages and warnings.

Gas Emissions

SO2 emissions from the summit, Pu῾u ῾Ō῾ō , and the Lower East Rift Zone are all at low levels. LERZ emissions on August 5-6 were ~ 200 tons/day; Pu῾u ῾Ō῾ō emissions on August 6-7 were 200-300 tons/day, and Summit emissions when last measured on July 19 were around 100 tons/day. This SO2 release represents the lowest SO2 emitted from Kīlauea for over a decade.

Despite the low emission rates, SO2 plumes were blown toward populated areas in east Hawai‘i by SE winds on August 9, and many individuals reported detecting the smell of sulfur. Weather conditions contributed to this, but in addition, as the eruption vents cool down, small amounts of H2S are generated. The human nose can detect H2S at very low levels, adding to the overall perception of increased sulfur emission.

Kīlauea Volcano Summit

It has been over a week since the most recent collapse event at the summit on August 2. Summit seismicity continues to be low over the last 24 hrs, with less than 5 located earthquakes per hour and a maximum magnitude of M2.0. Summit deflation is negligible.


HVO will continue to monitor Kīlauea closely for any signs of change in activity.

The next status report will be issued tomorrow morning unless significant changes occur.

Kīlauea Volcano Lower East Rift Zone (LERZ)

During an overflight of the LERZ this morning (August 11) two small ponds of lava were observed in the Fissure 8 cone. One pond is crusted over and stagnant, the other is incandescent and sluggishly convecting. A gas plume billows up from Fissure 8; low-level steaming from a handful of the other fissures (inactive) is intermittent. Lava is oozing at several points along the coastline creating wispy laze plumes.

Although the lull in LERZ activity continues, it is common for eruptions to go through periods of diminished output, or to pause completely, only to return with renewed vigor days or weeks later, or longer. Resumption of the activity on the LERZ could occur at any time, and residents should remain informed and heed Hawaii County Civil Defense messages and warnings.

Kīlauea Gas Emissions

SO2 emissions from the summit, Pu῾u ῾Ō῾ō , and the Lower East Rift Zone are all at low levels. LERZ emissions on August 5-6 were ~ 200 tons/day; Pu῾u ῾Ō῾ō emissions on August 6-7 were 200-300 tons/day, and Summit emissions when last measured on July 19 were around 100 tons/day. This SO2 release represents the lowest SO2 emitted from Kīlauea for over a decade.

CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Unrest continues at Cleveland volcano. Weakly elevated surface temperatures were observed over the past day in mostly cloudy satellite images. Web camera views were obscured. Nothing significant was detected in seismic or pressure sensor (infrasound) data during the last 24 hours.

Cleveland volcano is monitored by only two seismic stations, which restricts AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.


GREAT SITKIN VOLCANO (VNUM #311120)

Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Low-level unrest continues at Great Sitkin Volcano. Seismicity remains low, but above background levels. No volcanic activity was observed in mostly cloudy satellite images over the past day.

Great Sitkin Volcano is monitored with a local real-time seismic network, which will typically allow AVO to detect changes in unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption would be accomplished using a combination of seismic, infrasound, lightning, and satellite data.

The eruption remains suspened for now

KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE

Activity and Hazards Overview

Kīlauea Volcano has remained quiet for over a week now, with no further collapse events at the summit, and, with the exception of a small, crusted-over pond of lava deep inside the fissure 8 cone and a few scattered ocean entries, no lava flowing in the lower East Rift Zone (LERZ).

Earthquake and deformation data show no net accumulation, withdrawal, or significant movement of subsurface magma or pressurization as would be expected if the system was building toward a resumption of activity.

It is too soon to tell if this change represents a temporary lull or the end of the LERZ eruption and/or summit collapse activity. In 1955, similar pauses of 5 and 16 days occurred during an 88-day-long LERZ eruption. During the Mauna Ulu eruption (1969-1974), a 3.5 month pause occurred in late 1971.

Despite the eruptive pause, hazardous conditions remain in the LERZ and at the summit as described below:

● The fissure 8 crater still hosts a small amount of lava that currently does not enter the existing channel. Should the eruption rate increase, the configuration of outflow around the vent could change, sending lava in new directions. Possible flow paths to the north have been outlined in HVO’s 2018 lower East Rift Zone hazard assessment (https://volcanoes.usgs.gov/vsc/file_mngr/file-185/USGS%20Preliminary%20Analysis_LERZ_7-15-18_v1.1.pdf).

● Resupply of magma could lead to the reactivation of fissures other than fissure 8, or the opening of entirely new fissures along the ERZ, potentially leading to new areas being inundated by lava.

● The new lava flow field in the LERZ includes large areas of still-hot, rugged, and unstable lava surfaces that are subject to collapse.

● Sulfur dioxide (SO2) gas emissions have greatly decreased from LERZ vents, but high levels of SO2 may persist in downwind areas.

● Tephra (fragments of glassy lava) have accumulated to thicknesses of more than several feet near fissure 8. This material breaks down over time into small, glassy particles that can be blown on the wind and create an eye, respiratory, and skin irritant. Disturbing the tephra by sweeping, shoveling, or driving over it will break the fragile pieces into a glassy dust. The tephra can also conceal underlying hazards such as ground cracks, holes, and debris from destroyed structures.

● The LERZ ocean entry is minimally active at this time, but continued laze and lava delta collapses remain a concern. Hydrovolcanic explosions are much less of a concern now, as they require high eruption rates with lava entering the ocean, but they may still occur.

● At the summit, additional earthquakes, rockfalls, and ground cracking can occur with no warning. Steep crater walls destabilized by months of earthquakes could be prone to collapse for weeks or months to come, even without further ground shaking (https://volcanoes.usgs.gov/vsc/file_mngr/file-184/Summit%20scenarios_7-5-18.pdf).

● Summit SO2 emissions rates are lower than at any time since late 2007 and are not currently a hazard.

● Resuspended ash in the summit region remains a local hazard during strong winds.

● As the summit continues to adjust to changes in the underlying magmatic system, additional, and potentially damaging, earthquakes are possible. Hawai’i is known for frequent earthquakes, so all residents should be prepared for damaging earthquakes.

● If magma returns to the shallow reservoir beneath Kilauea’s summit, groundwater could encounter subsurface regions of high temperature, prompting explosions of uncertain size.

● More dangerous explosive activity at the summit remains very unlikely in the near term. For more information, see https://volcanoes.usgs.gov/vsc/file_mngr/file-184/Summit scenarios_7-5-18.pdf

● Aftershocks from the May 4, 2018 M6.9 earthquake below Kilauea’s south flank will continue for months more and could produce moderate, damaging events at any time.

The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea’s activity, including overflights of the rift zone and summit as needed, supplemented with unmanned aerial systems (UAS) flights and daily visual observations. Field crews will be deployed to the LERZ and the summit areas to collect data and to install and repair monitoring instruments. HVO will continue to issue daily updates and additional messages as needed.

The next status report will be issued tomorrow morning unless significant changes occur.

Kīlauea summit and lower East Rift Zone

The lull in activity at Kīlauea Volcano continues. No summit collapse events have occurred since August 2, and, with the exception of a small, crusted-over pond of lava deep inside the fissure 8 cone and a few scattered ocean entries, lava stopped flowing in the lower East Rift Zone (LERZ) on August 6. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007.

Earthquake and deformation data show no net accumulation, withdrawal, or significant movement of subsurface magma or pressurization as would be expected if the system was building toward a resumption of activity.

HVO/USGS Volcanic Activity Notice

Volcano: Kilauea (VNUM #332010)

Current Volcano Alert Level: WATCH
Previous Volcano Alert Level: WARNING

Current Aviation Color Code: ORANGE

Issued: Friday, August 17, 2018, 8:39 AM HST
Source: Hawaiian Volcano Observatory
Notice Number:
Location: N 19 deg 25 min W 155 deg 17 min
Elevation: 4091 ft (1247 m)
Area: Hawaii

Volcanic Activity Summary: Lowering Alert Level from WARNING to WATCH

In light of the reduced eruptive activity at Kīlauea Volcano over the last several days, HVO is lowering the Alert Level for ground based hazards from WARNING to WATCH. This change indicates that the hazards posed by crater collapse events (at the Kīlauea summit) and lava flows (Lower East Rift Zone; LERZ) are diminished. However, the change does not mean with absolute certainty that the LERZ eruption or summit collapses are over. It remains possible that eruption and collapse activity could resume.

Although no signs of imminent hazardous activity are present at this time, residents of the region near recently active fissures should stay informed, heed Civil Defense warnings, and be prepared, if necessary, to self-evacuate.

The aviation color code remains at ORANGE.

For definitions of Alert Levels and Aviation Color Codes, see: https://volcanoes.usgs.gov/vhp/about_alerts.html


The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea's seismicity, deformation, and gas emissions for any sign of reactivation, and maintain visual surveillance of the summit and LERZ. HVO will continue to issue daily updates and additional messages as needed.

Indeed, much too early.

Lulls in activity are normal, and an eruption is said to be continuous if it occurs within 3 months of the beginning of such a lull, and is not distinctly of a different type (eg, different magma chemistry).

Alas, we'll know when we know, and I wouldn't be counting any chickens before then.

Well what has changed is the input of fresh magma. For  along period it matched the output which is why the eurption has lasted so long. The overall time period 35 years generally also indicates that the end is going to be sooner rather than later. The Eruption is the longest observed and the lower east rift Eruption the longest ever.

Meanwhile Mauna Loa has resumed it's recent restlessness as a new injection of magma is happening. The volcano has been very quiet since it's last eruption in 1984 in contrast to its neighbor Kilauea. This is one it's longest pauses in it's History.

Kīlauea summit and lower East Rift Zone

Seismicity and ground deformation are negligible at the summit of Kīlauea Volcano. On the volcano's lower East Rift Zone (LERZ), only a few ocean entries are oozing lava; laze plumes are minimal from overflights over the past two days. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007. Yesterday, the SO2 emissions from the LERZ were too low to measure although SO2 smells were noticed.

Major Hurricane Lane is forecast to pass to the west of the island of Hawaiʻi and should not have a significant effect on the eruption aside from minor rockfalls at the summit and increased Puʻu ʻŌʻō and LERZ steaming. White out conditions could occur on the new lava field due to the interaction of heavy rain and still-hot lava flows.

The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea’s seismicity, deformation, and gas emissions for any sign of reactivation, and maintain visual surveillance of the summit and LERZ as best we can during the next few days while Hurricane Lane passes. Ground crews are not working in the field but remain on call should any changes in the volcano develop.

HVO will continue to issue daily updates and additional messages as needed. The next update will be issued tomorrow morning unless significant changes occur.

Low-level unrest continues. The Aviation Color Code and Volcano Alert Level were reduced to Yellow/Advisory earlier today, reflecting a pause in eruptive activity. Over the past day elevated surface temperatures were observed in satellite data during periods of clear weather and are interpreted to be due to hot degassing from vents in the the summit crater.

Kīlauea summit and lower East Rift Zone

Seismicity and ground deformation are negligible at the summit of Kīlauea Volcano. On the volcano's lower East Rift Zone (LERZ), only a few ocean entries were oozing lava; laze plumes were minimal from overflights on Monday and Tuesday. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007. On Tuesday, the SO2 emissions from the LERZ were too low to measure although SO2 smells were noticed.

Kīlauea summit and lower East Rift Zone

Seismicity and ground deformation are negligible at the summit of Kīlauea Volcano. On the volcano's lower East Rift Zone (LERZ), a small lava pond was visible deep within the fissure 8 cone from a Hawaii County Fire Department overflight this morning. A few ocean entries were oozing lava and laze plumes were minimal from HVO overflights at the beginning of this week. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007. On Tuesday (8/21), the SO2 emissions from the LERZ were too low to measure although SO2 smells were noticed. Our next overflight is scheduled for Monday morning (8/27).

Tropical Storm Lane is moving to the west this morning away from the Island of Hawaiʻi. Flooding remains a problem. The hurricane has had little effect on the eruption aside from minor rockfalls at the summit and increased steaming from Puʻu ʻŌʻō and LERZ vents; however, HVO lost communication with several monitoring stations on the east side of the island in the last two days but the losses only slightly reduce our ability to assess volcanic conditions. Whiteout conditions could occur on the new lava field due due to steam produced by heavy rainfall on still-hot lava flows.

The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea’s seismicity, deformation, and gas emissions for any sign of reactivation, and maintain visual surveillance of the summit and LERZ as best we can. Ground crews are not working in the field today but remain on call should any changes in the volcano develop.

HVO will continue to issue daily updates and additional messages as needed. The next update will be issued tomorrow morning unless significant changes occur.

 

CLEVELAND VOLCANO (VNUM #311240)

Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Low-level unrest continues. Satellite and web camera observations were obscured by clouds over the past day. No significant activity was detected in seismic or pressure sensor (infrasound) data over the past day.

Cleveland volcano is monitored by only two seismic stations, which restricts AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.


GREAT SITKIN VOLCANO (VNUM #311120)

Low-level unrest continues at Great Sitkin Volcano. Satellite observations were mostly obscured by clouds over the past day. No significant activity observed in seismic data.

Great Sitkin Volcano is monitored with a local real-time seismic network, which will typically allow AVO to detect changes in unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption would be accomplished using a combination of seismic, infrasound, lightning, and satellite data.

Kīlauea summit and lower East Rift Zone

Seismicity and ground deformation are negligible at the summit of Kīlauea Volcano. On the volcano's lower East Rift Zone (LERZ), a small lava pond was visible deep within the fissure 8 cone from a Hawaii County Fire Department overflight Saturday morning (8/25). A few ocean entries were oozing lava and laze plumes were minimal from HVO overflights at the beginning of this week (8/20, 21). Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007. On Tuesday (8/21), the SO2 emissions from the LERZ were too low to measure although SO2 smells were noticed. Our next overflight is scheduled for tomorrow morning (8/27).

The passing of Tropical Storm Lane has left the Island of Hawaiʻi in a Flash Flood Watch. The hurricane/tropical storm had little effect on the eruption aside from minor rockfalls at the summit and increased steaming from Puʻu ʻŌʻō and LERZ vents; however, HVO lost communication with several monitoring stations on the east side of the island in the last two days but the losses only slightly reduce our ability to assess volcanic conditions. Whiteout conditions could occur on the new lava field due due to steam produced by heavy rainfall on still-hot lava flows.

The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea’s seismicity, deformation, and gas emissions for any sign of reactivation, and maintain visual surveillance of the summit and LERZ as best we can. Ground and drone crews are in the field today but continue to be hampered by weather conditions.

HVO will continue to issue daily updates and additional messages as needed. The next update will be issued tomorrow morning unless significant changes occur.

Low-level unrest continues. Slightly elevated surface temperatures of the summit crater were observed in satellite images during periods of clear weather. This is interpreted as being due to hot gas emissions, which are typical for Cleveland at this low level of unrest.

Kīlauea summit and lower East Rift Zone

Seismicity and ground deformation are negligible at the summit of Kīlauea Volcano. On the volcano's lower East Rift Zone (LERZ), a small lava pond was visible deep within the fissure 8 cone on Saturday morning (8/25) but lava was no longer visible in the cone this morning. A single small lava dribble was oozing lava into the ocean from the Kapoho Bay lobe from an HVO overflight this morning and a sand bar still blocks the Pohoiki boat ramp. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007. On Tuesday (8/21), the SO2 emissions from the LERZ were too low to measure although SO2 smells were noticed.

Kīlauea summit and lower East Rift Zone

Seismicity remains low and ground deformation is negligible at the summit of Kīlauea Volcano. Earthquakes, probably aftershocks of the magnitude-6.9 earthquake in early May, continue on South Flank faults. On the volcano's lower East Rift Zone (LERZ), no incandescence was visible in the fissure 8 cone nor was there any lava entering the ocean during this morning's overflight. Sulfur dioxide emission rates at both the summit and LERZ are drastically reduced; the combined rate is lower than at any time since late 2007. On Tuesday (8/21), the SO2 emissions from the LERZ were too low to measure although SO2 smells were noticed.

KÄ«lauea summit and lower East Rift Zone

Seismicity remains low and ground deformation is negligible at the summit of KÄ«lauea Volcano. Earthquakes, probably aftershocks of the magnitude-6.9 earthquake in early May, continue on South Flank faults. On the volcano's lower East Rift Zone (LERZ), the last visible incandescence in the fissure 8 cone was observed on August 25. This morning's overflight crew saw no incandescence anywhere on the flow field and coastal area. Fissure 8 continues to fume. Sulfur dioxide emission rates at the summit, PuÊ»u ʻŌʻÅ, and LERZ are drastically reduced; the combined rate (< 1,000 t/d) is lower than at any time since late 2007.

The most recent deformation results in the LERZ do not show patterns that would be consistent with rift opening or closing. If the subsurface magma intrusion is cooling, those effects are not yet strong enough to be detectable.

Summit tiltmeter UWE was repaired and reinstalled yesterday and, after it settles from the disruption, will be returned to the Kilauea monitoring webpage. HVO crews continue to restore communication with several monitoring stations on the east side of the island that was disrupted by the passage of Hurricane/Tropical Storm Lane but the losses do not significantly reduce our ability to assess volcanic conditions. Whiteout conditions could occur on the new lava field due due to steam produced by heavy rainfall on still-hot lava flows.

The Hawaiian Volcano Observatory (HVO) will continue to closely monitor Kīlauea’s seismicity, deformation, and gas emissions for any sign of reactivation, and maintain visual surveillance of the summit and LERZ as best we can. Ground and drone crews are in the field today but continue to be hampered by weather conditions.

HVO will continue to issue daily updates and additional messages as needed. The next update will be issued tomorrow morning unless significant changes occur.
