AVO Cleveland YELLOW/ADVISORY - Unrest continues. No significant activity detected in monitoring data.

By Newsroom America Feeds at 18 Mar 2018

Mar 18, 2018 19:37 - Unrest continues at Cleveland volcano. Nothing significant was observed in cloudy satellite images over the past day, and no activity was detected by geophysical sensors. Cleveland volcano is monitored by only two seismic stations, which restricts 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.
