Eruption news from Cleveland volcano:

A small and short-lived explosive eruption occurred earlier today. The Alaska Volcano Observatory (AVO) detected it on seismic data to have been at at 3:17 UTC December 29 (18:17 AKST December 28) and a pilot reported seeing an ash cloud to 17,000 ft asl. Local winds are from the west.

"Explosions from Cleveland typically produce relatively small volcanic ash clouds that dissipate within hours; however, more significant ash emissions are possible.

"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." (AVO)

Thursday, Jun 28, 2018
The Alaska Volcano Observatory (AVO) reported on Tuesday evening 26 June 2018 that satellite images obtained from Cleveland volcano the day before show a small circular lava flow of about 80 meters (260 feet) diameter covering the floor of the summit crater. The presence of a lava flow over the active vent increases the possibility of a vent clearing explosion over the coming days to weeks and thus AVO is raising the Aviation Colour Code ORANGE and the Volcano Alert Level to WATCH. ...
