AVO Cleveland YELLOW/ADVISORY - Low-level unrest continues. No unusual activity detected in monitoring data.
Apr 16, 2018 21:06 - Low-level unrest continues at Cleveland Volcano. No activity was observed in partly cloudy satellite data, and no significant activity was detected in seismic or infrasound data, over the past day. 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.
