Pavlof volcano (Alaska Peninsula, USA) activity update: latest eruption ended
Wednesday Nov 26, 2014 08:22 AM | AUTEUR : TThe Alaska Volcano Observatory concluded that "the most recent period of explosive eruptive activity at Pavlof Volcano has ended" and downgraded the volcano alert level again.
"For about the past week, seismicity at the volcano has remained at low levels and shows no indication of the unrest typically associated with lava fountaining or ash emission.
Satellite observations show no evidence for continuing eruptive activity. Thermal signals at the summit are occasionally visible, but are likely being generated by the cooling of previously emplaced lava and debris and not newly erupted material.
The low levels of seismic activity and the lack of evidence for continued lava effusion indicate that the brief eruption has ended and thus AVO is lowering the Aviation color code and Volcano Alert Level to YELLOW/ADVISORY."
