HVO Kilauea YELLOW/ADVISORY - Low activity levels across the volcano, no lava at the surface.

USGS Volcano Current Alerts - Tue, 11/20/2018 - 21:32
Nov 21, 2018 02:18 - Activity Summary: Kīlauea Volcano is not erupting. Rates of seismicity, deformation, and gas release have not changed significantly over the past week. Deformation signals are consistent with refilling of the middle East Rift Zone. Observations: HVO monitoring during the past week shows low rates of seismicity at the summit and East Rift Zone (ERZ). Earthquakes continue to occur primarily at Kīlauea's summit and south flank areas. Also, small aftershocks of the May 4, 2018 magnitude-6.9 quake continue to occur. In the ERZ, tiltmeters near Puʻu ʻŌʻō and ...

AVO Great Sitkin YELLOW/ADVISORY - Unrest continues; no explosive activity detected

USGS Volcano Current Alerts - Tue, 11/20/2018 - 14:32
Nov 20, 2018 20:17 - Low-level unrest continues at Great Sitkin volcano. Numerous small earthquakes associated with the ongoing unrest continue to be recorded on the local seismic network. No activity was observed in cloudy satellite images. No explosive activity was detected on a regional infrasound array on Adak Island. 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, ...

AVO Cleveland YELLOW/ADVISORY - Unrest continues; no activity observed in partly cloudy satellite images

USGS Volcano Current Alerts - Tue, 11/20/2018 - 14:32
Nov 20, 2018 20:17 - Low-level unrest continues at Cleveland volcano. Nothing significant has been detected in seismic or regional infrasound data over the past day. Nothing seen in mostly cloudy satellite images. 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. The web camera, one seismic station, and the local infrasound array are offline due to ...

AVO Semisopochnoi ORANGE/WATCH - No activity seen in satellite data or regional infrasound; seismic data out

USGS Volcano Current Alerts - Tue, 11/20/2018 - 14:32
Nov 20, 2018 20:17 - No eruptive activity was observed in partly cloudy satellite imagery or regional infrasound over the past day. The satellite link that transmits seismic data from Semisopochnoi failed on November 1, but an infrasound array on Adak Island should still detect significant explosive emissions from Semisopochnoi (with a 13-minute delay) if atmospheric conditions permit. Additional explosions are possible and will likely occur without warning. Semisopochnoi is monitored with an on-island seismic network, though this is currently off-line, and remotely by satellite and ...

AVO Veniaminof ORANGE/WATCH - Eruption continues; continued lava effusion and minor plume above vent

USGS Volcano Current Alerts - Tue, 11/20/2018 - 14:32
Nov 20, 2018 20:17 - Veniaminof volcano continues to erupt with effusion of a lava flow from the cone in the ice-filled summit caldera, and continuous seismic tremor. Increased seismicity was noted over the past 18 hours but no significant changes were noted in satellite observations. Clear satellite views of the volcano over the past day continued to show strongly elevated surface temperatures from the active lava effusion and occasional low elevation plumes around 10,000 feet. A few clear web camera images showed incandescence from the lava emission overnight. Diffuse ash and steam ...

AVO Veniaminof ORANGE/WATCH - Eruption continues; continued lava effusion and minor plume above vent

USGS Volcano Current Alerts - Mon, 11/19/2018 - 14:32
Nov 19, 2018 20:21 - Veniaminof volcano continues to erupt with effusion of a lava flow from the cone in the ice-filled summit caldera, and continuous, low-amplitude seismic tremor. Clear satellite views of the volcano over the past day showed strongly elevated surface temperatures from the active lava effusion.

AVO Great Sitkin YELLOW/ADVISORY - Unrest continues; seismicity elevated; small explosion detected

USGS Volcano Current Alerts - Fri, 11/16/2018 - 18:31
Nov 16, 2018 22:37 - Low-level unrest continues at Great Sitkin Volcano. Seismicity remains elevated with small earthquakes occurring at rates above background levels.

AVO Cleveland YELLOW/ADVISORY - Unrest continues; seismicity low; elevated surface temperatures observed

USGS Volcano Current Alerts - Fri, 11/16/2018 - 18:31
Nov 16, 2018 22:37 - Nothing significant was detected in seismic or infrasound (pressure) sensor data this week. Elevated surface temperatures in the summit region were observed in satellite data several times this week. Future explosive activity is likely and is expected to occur without warning. Previous explosions have produced hazardous conditions primarily near the volcano, but occasionally they have been large enough to produce a drifting ash cloud. Cleveland volcano is monitored by only two seismic stations, which restricts AVO's ability to detect precursory unrest that may ...
