HVO Kilauea ORANGE/WARNING - LERZ lava eruption ongoing; summit collapse-explosion events continue almost daily.

USGS Volcano Current Alerts - Tue, 07/17/2018 - 19:32
Jul 17, 2018 23:43 - Kīlauea Volcano Lower East Rift Zone Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. Surging was noted at the Fissure 8 cone during the overflight but had stopped by the time ground crews arrived to verify it. Lava in the channel is a bit lower this morning and there were no significant overflows. The southern margin of the flow was located about 750 m (0.5 mi) from the boat ramp at Isaac Hale Park this morning. Despite no visible surface connection to the fissure 8 channel, lava continues to ooze out at several points ...

AVO Great Sitkin YELLOW/ADVISORY - No significant activity observed in satellite.Seismicity at low levels.

USGS Volcano Current Alerts - Tue, 07/17/2018 - 16:32
Jul 17, 2018 21:12 - Unrest continues at Great Sitkin Volcano. Seismic activity remains at low levels. No significant activity was observed in mostly cloudy satellite data 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.

AVO Cleveland ORANGE/WATCH - Unrest continues.No significant actiivty observed in satellite or seismic data..

USGS Volcano Current Alerts - Tue, 07/17/2018 - 16:32
Jul 17, 2018 21:12 - Unrest continues at Cleveland volcano. No anomalous activity was observed in mostly cloudy satellite data and no significant activity was observed in seismic or pressure sensor (infrasound) data during 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.

USGS Volcano Current Alerts - Mon, 07/16/2018 - 16:30
Jul 16, 2018 19:31 - Kīlauea Volcano Lower East Rift Zone Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. The channel is full but not quite up to the rim; there were no significant overflows this morning. The southern margin of the flow remained about 1 km (0.6 mi) from Isaac Hale Park this morning. Despite no visible surface connection to the fissure 8 channel, lava continues to ooze out at several points on the 6 km (3.7 mi) wide flow front into the ocean. Explosions were reported from the main ocean entry this morning with at least one ...

Jul 15, 2018 21:21 - Kīlauea Volcano Lower East Rift Zone Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. Lava levels in the upper channel increased briefly following this morning's summit collapse-explosion event at 3:26 a.m. Another short-lived overflow of the channel at the vent spread east-southeast this morning, but did not advance beyond the existing flow field. The channelized ʻaʻā flow west of Kapoho Crater continues to be the main ocean entry at the southern edge of the flow front. The southern margin of the flow remained about 1 ...

Jul 14, 2018 21:23 - Kīlauea Volcano Lower East Rift Zone Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. Lava levels in the upper channel increased for several hours after the summit collapse-explosion event yesterday at 7:08 p.m. and returned to lower levels this morning. A short-lived overflow of the channel near the vent spread east-southeast, but did not advance beyond the existing flow field. The channelized ʻaʻā flow west of Kapoho Crater continues to be the main ocean entry at the southern edge of the flow front this morning. The ...

These include Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams in Washington State; and Mount Hood, Mount Jefferson, Three Sisters, Newberry, and Crater Lake in Oregon. Recent Observations: Monitoring systems show that activity at Cascade Range volcanoes remained at background levels throughout the week. Field crews were at Mount Rainier and Crater Lake this work scouting station locations.

Jul 13, 2018 20:35 - Kīlauea Volcano Lower East Rift Zone Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. Lava levels in the upper channel between Fissure 8 and Pohoiki Rd. are low this morning but are expected to rise after the next collapse/explosive vent at Kīlauea summit. The channelized ʻaʻā flow west of Kapoho Crater continues to be the main ocean entry at the southern edge of the flow front this morning.

Seismicity levels throughout the week have remained low with a slight uptick in small, local earthquakes starting on Thursday, July 12. Local observers reported active steaming from the fumaroles on Great Sitkin on Tuesday, July 10. The most recent significant activity was a small emission of ash and steam on June 10, 2018. Great Sitkin Volcano is monitored with a local real-time seismic network, which will typically allow AVO to detect changes in unrest ...

AVO Cleveland ORANGE/WATCH - Low-level unrest continues.

USGS Volcano Current Alerts - Fri, 07/13/2018 - 16:31
Jul 13, 2018 18:54 - Low-level unrest continues at Cleveland volcano. Weakly elevated surface temperatures consistent with cooling lava were observed in high resolution satellite data on July 11 when weather conditions were clear. No significant activity was detected in seismic and pressure sensor data throughout the past week. Future explosive activity is likely and is expected to occur without warning. Previous explosions have produced hazardous conditions primarily near the summit crater, but occasionally they have been large enough to produce a drifting ash cloud. Cleveland ...

USGS Volcano Current Alerts - Thu, 07/12/2018 - 18:30
Jul 12, 2018 20:51 - Kīlauea Volcano Lower East Rift Zone Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. Lava levels in the upper channel between Fissure 8 and Pohoiki Rd. are low this morning but are expected to rise after the next collapse/explosive vent at Kīlauea summit. Overnight, the diverted channelized ʻaʻā flow west of Kapoho Crater advanced to the ocean destroying the Kua O Ka La Charter School and Ahalanui Count Beach Park and establishing a robust ocean entry. Despite no visible surface connection to the Fissure 8 channel, ...

Jul 11, 2018 22:45 - Kīlauea Volcano Lower East Rift Zone Fissure 8 continues to erupt lava into the perched channel leading northeastward from the vent. The upper channel between Fissure 8 and Pohoiki Rd. started overflowing about 8:30 or 9 am with a few lobes advancing a short distance beyond previous flows threatening a few houses on Luana and Nohea Streets. Last night and this morning, the channel was apparently blocked again just west of Kapoho Crater and a majority of channel lava began flowing south along the west edge of previous flows west of Kapoho Crater. By 10 am, this ...
