This new eruption started just over one year after the last eruption at Pavlof and judging from the images of the eruption (see below) taken from nearby, the activity appears to be pretty similar, with strombolian eruptions and possibly lava flows moving down the flanks of the volcano. Last year’s activity lasted a few months before the volcano quieted and the alert status was moved to Green/Normal until AVO moved the volcano back to Orange/Watch on May 31.
You can catch a glimpse of the eruption on the FAA webcam in Cold Bay. Be sure to check out some of the images of the current activity on the AVO website as well."

"Pavlof Volcano, volcanic peak of the Aleutian Range, southwestern Alaska, U.S. Situated about 580 miles (930 km) southwest of Anchorage, on the west side of Pavlof Bay, it lies near the southwestern tip of the Alaska Peninsula. Rising to more than 8,260 feet (2,518 metres), Pavlof is one of the tallest volcanoes in Alaska. It is also one of the most consistently active, having had about 40 eruptions recorded since 1790. Just northeast of Pavlof Volcano stands its “twin,” a volcano known as Pavlof Sister (7,028 feet [2,142 metres]). Pavlof Sister is also active, but no eruptions have been reported there since 1762. Built high on a base of older volcanic rock, the two symmetrical, cone-shaped peaks are a prominent feature of the landscape."

"The Pavlof Volcano on the Alaska Peninsula has started erupting but it’s considered a low level eruption.
The Alaska Volcano Observatory raised the volcano alert level to “Watch” on Saturday after detecting a thermal anomaly at the summit of the volcano Saturday morning.
AVO issued an update Sunday afternoon confirming that the elevated surface temperatures persist at the summit of the volcano and weak incandescent glowing at the summit was observed Saturday night in the FAA web cam in Cold Bay. AVO confirms that no ash clouds have been detected in satellite images.
Some weak seismic activity is being detected on the network set up on the Pavlov Volcano and AVO confirms that some small explosion signals were detected by a distant infrasound sensor.
The National Weather Service issued a special statement Saturday afternoon about the eruption of the Pavlof Volcano. The Weather Service is warning that very light ash fall is possible in the vicinity of the volcano.
The Pavlof Volcano is 8,200 feet above sea level and there have been about 40 historic eruptions. It’s considered one of the most consistently active volcanos in the Aleutian arc. Cold Bay is about 37-miles southwest of the volcano. You can follow all of the activity at the volcano on the website of the Alaska Volcano Observatory."
