Pavlof volcano news & activity updates:

Pavlof volcano (Alaska): increased seismic activity, pilot report of possible ash emissions

Donnerstag Jun 08, 2017 07:18 | VON: T

The volcano has been showing increased seismic activity over the past several days, and there might be minor eruptive activity occurring, as the Alaska Volcano Observatory noted:
"... there has been an increase in low-frequency earthquake activity at Pavlof. Such increases are sometimes seen prior to eruptive episodes, however in other cases they decline without eruptive activity.
"In addition, several short duration tremor-bursts have been observed today, and AVO received a pilot report of a possible ash cloud this afternoon. Infrasound data from local instruments on Pavlof and from a more distant network in Sand Point do not show any evidence of significant explosive activity.
"Precursory activity prior to eruptions of Pavlof are always very subtle, thus, on the basis of these observations we are increasing the Aviation Color Code to Yellow and the Alert Level to Advisory." (AVO)

Seismic activity of the volcano has increased again during the past 48 hours. Satellite data show at least some small ash emissions have taken place although the Alaska Volcano Observatory does not speak of a new eruption taking place (such ash emissions could be related to collapses in the crater etc without new magma erupting). ...
