Eruption news from Cleveland volcano:

Cleveland volcano (Alaska) activity update: occasional explosions, summit lava dome destroyed

Thursday Apr 12, 2012 10:05 AM | BY: T

AVO reported that a small explosion from Cleveland was detected at 0112 on 4 April by distant seismic stations and infrasound arrays. Weather conditions prevented the detection of a possible eruption cloud in satellite images or by visual observation of the summit. Observations the next day revealed a thermal anomaly and that the 70-m-diameter lava dome had been destroyed by the explosion. This was the third lava dome that was erupted and subsequently destroyed by explosive events since the eruption began in July 2011.
On 6 April two short-duration explosions occurred at about 1635 and 2126. The resulting eruption clouds were ash poor and did not rise above 3 km (10,000 ft) a.s.l. Elevated surface temperatures were observed using infrared satellite images near the times of the explosions. Satellite observations were obscured by clouds during 8-10 April. No seismic information was available because Cleveland does not have a real-time seismic network.
