ALASKA VOLCANO OBSERVATORY DAILY UPDATE

CLEVELAND VOLCANO (VNUM #311240)
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. Elevated surface temperatures at the summit observed in one satellite image of the volcano over the past day; all other images show nothing noteworthy. A few small earthquakes were detected at the volcano over the past day, but otherwise, no unusual activity detected in seismic or pressure sensor data.

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.
