|(8) Volcano Location:||N 52 deg 49 min W 169 deg 56 min|
|(10) Summit Elevation:||5676 ft (1730 m)|
|(11) Volcanic Activity Summary:||Satellite data show that the recent explosion of Cleveland volcano at 05:49 UTC (21:49 local time) produced a small ash cloud up to 22,000 ft asl moving southeast. No other significant activity has been detected.
Explosions from Cleveland typically produce relatively small volcanic ash clouds that dissipate within hours; however, more significant ash emissions are possible.
Cleveland volcano is monitored with a limited real-time seismic network, which inhibits 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.
