|(8) Volcano Location:||N 52 deg 49 min W 169 deg 56 min|
|(10) Summit Elevation:||5676 ft (1730 m)|
|(11) Volcanic Activity Summary:||Local seismic sensors recorded a short-lived explosion today at 3:17 UTC December 29 (18:17 AKST December 28). A pilot report indicates an ash cloud to 17,000 ft asl. Local winds are from the west.
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.
