AVO Cleveland ORANGE/WATCH - No activity observed in satellite, seismic or infrasound data.
Jun 17, 2017 20:45 - No unusual activity has been detected in seismic or infrasound data from the past day. Clouds obscured views of the volcano by satellite and web camera. 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.
