Mount Pavlof is a stratovolcano on the Alaska Peninsula and lies on the shores of Pavlof Bay . It is currently the most active volcano in the Aleutian chain . The summit area of the conical volcano is covered with snow. From the summit a clear ridge runs southwest to the edge of the Emmons Lake Caldera . The volcanic cone measures approximately seven kilometers in diameter. There are active chimneys on the north and east sides near the summit area . The name "Pavlof" is of Russian origin and a translation of Saint Paul .
The very last eruption began on March 27, 2016 and caused ash to rise to a height of 6,000 m on March 28. The strongest of 3 eruptions in 2014 caused ash to rise to a height of 9000 m.
An eruption began on November 12, 2014 and had decreased significantly in intensity since November 16. In 2014 there was already an eruption that started in late May and lasted until the end of July. There was also an outbreak in 2013. This began in mid-May and lasted until the beginning of August, when the ash cloud reached a height of 6000 meters. Lava poured over the northwest flank.
Forty eruptions have been recorded since records began in 1790. Since the eruptions strangely often occur between September and December, it seems to be the most predictable of all active volcanoes in the Aleutian chain. The eruptions are often accompanied by severe earthquakes. The largest known outbreak occurred in 1911 at the end of a five-year period of activity. During this eruption, a rift opened on the northern flank of the volcano and erupted large boulders and lava flows.
