HVO Kilauea ORANGE/WATCH - Kīlauea's eruption lull continues.

USGS Volcano Current Alerts - Wed, 08/29/2018 - 20:31
Aug 30, 2018 01:25 - 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 ...

AVO Great Sitkin YELLOW/ADVISORY - Unrest continues. No significant activity observed in seismic or satellite data.

USGS Volcano Current Alerts - Wed, 08/29/2018 - 17:31
Aug 29, 2018 21:52 - Low-level unrest continues at Great Sitkin Volcano. No significant activity was observed over the past day in seismic data or in cloudy satellite images. 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 YELLOW/ADVISORY - Unrest continues. No significant activity observed in seismic or satellite data.

USGS Volcano Current Alerts - Wed, 08/29/2018 - 17:31
Aug 29, 2018 21:52 - Low-level unrest continues. Slightly elevated surface temperatures were observed in one satellite image with a relatively clear view of the volcano yesterday afternoon . This is interpreted as being due to hot gas emissions from the summit crater, which are typical for Cleveland volcano at this low level of unrest. Web camera observations were obscured by clouds, and 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 ...

HVO Kilauea ORANGE/WATCH - Kīlauea's eruption lull continues.

USGS Volcano Current Alerts - Tue, 08/28/2018 - 18:31
Aug 28, 2018 22:28 - 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), 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 yesterday morning or during UAS flights later in the day. A single small lava dribble was oozing lava into the ocean from the Kapoho Bay lobe and a ...

USGS Volcano Current Alerts - Mon, 08/27/2018 - 23:30
Aug 28, 2018 01:38 - 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 ...

HVO Kilauea ORANGE/WATCH - Kīlauea's eruption lull continues.

USGS Volcano Current Alerts - Sun, 08/26/2018 - 17:31
Aug 26, 2018 20:40 - 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 ...

HVO Kilauea ORANGE/WATCH - Kīlauea's eruption lull continues.

USGS Volcano Current Alerts - Fri, 08/24/2018 - 15:31
Aug 24, 2018 20:30 - 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 and laze plumes were minimal from overflights early 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, the SO2 emissions from the LERZ were too low to measure although SO2 smells were noticed. Our overflight, originally scheduled for this ...

AVO Great Sitkin YELLOW/ADVISORY - Low-level unrest continues. Possible small explosion on August 21.

USGS Volcano Current Alerts - Fri, 08/24/2018 - 15:31
Aug 24, 2018 20:19 - Low-level unrest continues at Great Sitkin Volcano. Over the past week the rate of small earthquakes located beneath the summit has increased slightly, although the rate of these quakes is not unusual since unrest began in July of 2016. A seismic event that may represent a small steam explosion was observed on Tuesday August 21 at 12:37 AM Alaska Time. This event was considerably smaller than those observed in June and August 2018 and in 2017 and explosive activity was not confirmed by satellite imagery or infrasonic measurements. Satellite observations have been mostly ...

AVO Cleveland YELLOW/ADVISORY - Unrest continues. Seismicity is low. Elevated surface temperatures observed.

USGS Volcano Current Alerts - Fri, 08/24/2018 - 15:31
Aug 24, 2018 20:19 - Unrest continues at Cleveland volcano. The Aviation Color Code was reduced to Yellow and the Volcano Alert Level to Advisory on August 22 due to a pause in eruptive activity. Elevated surface temperatures in the summit crater continue to be observed in satellite data during periods of clear weather, but are interpreted to be due to hot degassing. This is typical of Cleveland volcano and indicates that low-level unrest continues. No significant activity was detected in seismic and infrasound (pressure) sensor data throughout the week. Future explosive activity is ...
