Eruption news from Cleveland volcano:
Cleveland volcano (Aleutian Islands, Alaska): continuous weak eruptions
Mon, 6 May 2013, 06:5606:56 AM | BY: T
After the initial explosion 2 days ago, continuous small eruptions produced a steam and ash plume yesterday and decreased in intensity again today. The activity of the volcano, which is not monitored on ground, was detected by satellite data and infrasonic tremor measured by ground-coupled airwaves on the nearby Okmok seismic network, 120 km (80 mi) to the northeast.

A faint plume extended eastward below 15,000 ft. Satellite data also continue to show highly elevated surface temperatures at the summit.
Sudden explosions of blocks and ash are possible with little or no warning. Ash clouds, if produced, could exceed 20,000 feet above sea level.

AVO received no other reports of activity. (USGS / AVO) ... read all
