AVO Cleveland YELLOW/ADVISORY - Unrest continues. No significant activity detected in monitoring data streams.
Mar 6, 2018 21:56 - Unrest continues at Cleveland volcano. No significant activity was detected by seismic or infrasound sensors over the past 24 hours, but elevated surface temperatures (likely from the emission of hot gases rather than lava effusion) were observed in thermal satellite data. 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 ...
