ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, May 17, 2018, 11:07 AM AKDT (Thursday, May 17, 2018, 19:07 UTC)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Low-level unrest continues at Cleveland volcano. Weakly elevated surface temperatures were observed in satellite images from the past day. Data streams from the seismic and pressure sensor stations on Cleveland remain out due to a power outage in Nikolski. Efforts are ongoing to restore the network. A large explosion from Cleveland, should it occur, would be detected on other pressure sensor and seismic networks in the region.
Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.
