Pavlof volcano news & activity updates:
Pavlov volcano (Alaska): eruption is pausing or ended
Wednesday May 29, 2013 08:41 AM | DOOR: T
The eruption might have ended already, or is at least pausing for the moment. Over the past few days, the eruptive and seismic activity have greatly declined, the Alaska Volcano Observatory reports.
There are no longer volcanic tremor or small explosions detected and satellite observations show no evidence of elevated surface temperatures, volcanic gas or ash emissions. There have been no visual observations from pilots or web cameras of any eruptive activity. "Consequently, the Aviation Color Code is being reduced to Yellow and the Volcano Alert Level to Advisory.
During past eruptions of Pavlof, the style of eruptive activity fluctuated from higher to lower levels. Therefore, this pause in eruptive activity does not necessarily indicate that the eruption has ended. Renewed activity is possible, and may not be preceded by significant seismic activity."

The eruption continues at low levels (both as surface lava emission and seismic activity). ... [meer...]

Weak activity (probably minor lava effusion) continues at the volcano, visible on satellite imagery as a thermal anomaly. AVO only observed degassing and almost no ash emissions, but maintains orange alert level in case eruptive activity restarts. [meer...]

The eruption at Pavlov continues but seismic and eplosive-effusive eruptive activity have dropped compared to the day before yesterday when an ash plume reached 7,000 m altitude and was visible from space. [meer...]

The eruption continues with no significant changes. Small lava fountaining, explosions, and the explosive interaction of the lava flow with snow and ice generate a plume of steam, ash, and gas, occasionally reaching up to 22,000 ft. above sea level, and extending primarily southeast from the volcano over the North Pacific Ocean visible in satellite images. ...

The eruption continues with lava fountaining, an active lava flow and ash emissions, accompanied by continuous seismic tremor. Aerial observations suggest that the interaction of lava and ice on the upper slope of the volcano create mud flows and pyroclastic flows. ... [meer...]
