Pavlof volcano news & activity updates:

Pavlof volcano (Alaska): no recent significant activity, alert lowered to green (normal)

mercredi août 30, 2017 23:42 | AUTEUR : T

Since mid June, 2017, unrest at the volcano has gradually declined to levels considered as normal background or normal.
The March 2016 eruption changed the configuration of the summit crater, such that it is slightly wider and has a more vertical orientation than before the 2016 eruption. Since then, the volcano has remained relatively quiet, although there was a brief period of elevated seismicity in early June, 2017 that resulted in AVO raising the Aviation Color Code to Yellow and the Alert Level to Advisory.
Many satellite views of the summit are now able to detect elevated surface temperatures within the crater and upper part of the volcanic conduit most likely associated with the emission of hot gases.
This is now considered the normal thermal state of the volcano. Occasional emission of vapor plumes from the summit crater, sometimes visible from Cold Bay and Sand Point, is now relatively common. These emissions are also considered normal background behavior for Pavlof Volcano. On the basis of these observations, and the lack of any noteworthy seismic activity for the past several months, we are lowering the Aviation Color Code to Green and the Alert Level to Normal.(AVO)
