ALASKA VOLCANO OBSERVATORY DAILY UPDATE U.S. Geological Survey Wednesday, May 25, 2016, 12:07 PM AKDT (Wednesday, May 25, 2016, 20:07 UTC)
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. Seismicity remains low. Weakly elevated surface temperatures were observed in mostly clear views by satellite today. This is consistent with the presence of the new lava dome in the summit crater that was first noted on May 18, 2016. The size of the dome has not changed since May 23, 2016 suggesting the extrusion of lava has paused. No other signs of eruptive activity have been observed in satellite or pressure sensor data today.
55°25'2" N 161°53'37" W,
Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Unrest continues at Pavlof Volcano. Seismicity remains low. No signs of eruptive activity have been observed in satellite or web camera images today.
Pauses in activity of days to weeks are common during eruptive episodes of Pavlof Volcano. A return to eruptive activity remains possible and could occur with little or no warning. Thus, AVO will continue to monitor the volcano closely and will issue additional information as necessary.
AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
