ALASKA VOLCANO OBSERVATORY DAILY UPDATE
Saturday, October 5, 2013 11:26 AM AKDT (Saturday, October 5, 2013 19:26 UTC)


CLEVELAND VOLCANO (CAVW #1101-24-)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

The character of unrest at Cleveland volcano has changed over the past twelve hours. Infrasound (pressure) sensors located on Okmok volcano about 140 km (85 miles) northeast have begun showing continuous pressure waves (likely from gas jetting)and occasional discrete small explosions coming from Cleveland. Satellite data show scattered low clouds in the area, but no evidence of ash emissions or elevated surface temperatures that would accompany the eruption of lava. AVO will continue to watch Cleveland closely with distant infrasound sensors and satellite data. Additional information updates will be issued if conditions warrant.

VENIAMINOF VOLCANO (CAVW #1102-07-)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Low-levels of seismicity continued at Veniaminof over the past day. Satellite images from clear periods over the past day show slightly elevated surface temperatures consistent with cooling of the previously erupted lava.
