AVO Cleveland YELLOW/ADVISORY - Unrest continues.No activity observed in seismic, infrasound or satellite data.
Feb 24, 2018 20:50 - Unrest continues at Cleveland volcano. No significant activity was observed in seismic, infrasound or satellite data over the last 24 hours. Clouds mostly obscured views of the summit today. 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.
