AVO Cleveland ORANGE/WATCH - No activity observed in satellite, seismic or infrasound data. Steaming in web camera.
Jun 18, 2017 20:34 - Unrest continues. No unusual activity has been detected in seismic or infrasound data from the past day. Clouds obscured views of the volcano by satellite and light steaming from the summit was observed in web camera views. 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.
