ALASKA VOLCANO OBSERVATORY DAILY UPDATE U.S. Geological Survey Tuesday, July 3, 2018, 10:55 AM AKDT (Tuesday, July 3, 2018, 18:55 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. Satellite data from today suggest no significant change in the summit lava dome. Low-level seismic activity is ongoing, but nothing significant was observed 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 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.
GREAT SITKIN VOLCANO
52°4'35" N 176°6'39" W,
Summit Elevation 5709 ft (1740 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Unrest continues at Great Sitkin volcano. Seismicity remains only slightly above background levels today. Clouds obscured views of the volcano by satellite day.
