|(7) Notice Number:|
|(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 and infrasound sensors recorded a small explosion tonight at 05:49 UTC (21:49 local time). A few small earthquakes were also recorded at the volcano during the previous several days. No other significant activity was detected. No volcanic cloud has been detected in satellite imagery.
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.
