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. ...

Introduction:The 2519-m-high, largely snow-capped Holocene stratovolcano was constructed along a line of vents extending NE from the Emmons Lake caldera.Pavlof and its twin volcano to the NE, 2142-m-high Pavlof Sister, form a dramatic pair of symmetrical, glacier-covered stratovolcanoes that tower above Pavlof and Volcano bays. A third cone, Little Pavolf, is a smaller volcano on the SW flank of Pavlof volcano, near the rim of Emmons Lake caldera. Unlike Pavlof Sister, Pavlof has been frequently active in historical time, typically producing strombolian to vulcanian explosive eruptions from the summit vents and occasional lava flows. The active vents lie near the summit on the north and east sides. The largest historical eruption of Pavlof took place in 1911, at the end of a 5-year-long eruptive episode; a fissure opened on the northern flank of the volcano, ejecting large blocks and issuing lava flows. --- Source: GVP (Global Volcanism Program), Pavlov information |
