Eruption news from Cleveland volcano:

Cleveland volcano (Aleutian Islands, Alaska): small ash eruptions and growing lava dome

Thursday Mar 15, 2012 11:05 AM | BY: T

Cleveland Volcano in the Aleutian Islands has had a few small explosive ash eruptions, the last one on 14 March, the Alaska Volcano Observatory (AVO) reports.
The lava dome in the summit crater continues to grow slowly and more eruptions are likely.
AVO writes: "As long as the volcano remains active, additional explosions are likely. Some may produce ash clouds exceeding 20,000 feet above sea level. These clouds may go undetected in satellite imagery for hours. If a large ash-producing event occurs, seismic, infrasound, or volcanic lightning would likely be detected by local and regional monitoring networks. There is no real-time seismic monitoring network on Cleveland volcano."
