AVO Cleveland YELLOW/ADVISORY - Unrest continues. No significant activity observed in seismic or satellite data.

23 Apr 15:39 | SciTech

Apr 23, 2017 19:16 - No significant volcanic activity has been detected in satellite, seismic or infrasound data over the past day. 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. read more »

Apr 23, 2017 19:16 - No significant volcanic activity was observed at Bogoslof volcano in seismic, infrasound data or satellite data over the past day. Bogoslof volcano remains at a heightened state of unrest and in an unpredictable condition. Activity may ramp back up with additional explosions producing high-altitude (>15,000 ft) volcanic clouds with little precursory activity. Some previous explosions have been preceded by an increase in earthquake activity that allowed for short-term forecasts of imminent significant explosive activity. Although we are able to detect energetic ...read more »
