Roundup of Global Volcanic Activity:
Cleveland (Aleutian Islands, Alaska): Small, brief explosions were detected at the volcano yesterday evening (21:29 UTC or 12:29 AKST) and this morning at 4:06 UTC (19:06 AKST local time), USGS reported.
“No satellite images available after the time of the explosion, so uncertain if minor ash cloud generated, but unlikely. “Similar such explosions may continue without warning, and may produce minor ash clouds that are not expected to extend much beyond the volcano, but could produce local fallout on the flanks of the volcano. AVO has received no reports of activity from local observers.” (AVO/USGS)
San Miguel volcano (El Salvador): The new eruption that occurred at the volcano Sunday (29 Dec) morning at 10:50 am local time has so far been an isolated single explosion of vulcanian type (accumulated pressure ejecting the plug in the conduit). Current seismic activity is low, but more activity could follow.
The explosion produced an ash plume of considerable (3-8 km) height, reaching estimated altitudes of 5-10 km. Heavy ash fall followed the eruption in nearby areas downwind, such as in the towns of Chinameca and San Jorge to the west. Civil Protection immediately began to evacuate families residing in a radius of 3 km around the volcano. So far, more than 5000 persons have been ordered to evacuate.
