Volcano Activity Discussion

Mount Pavlof joined Mount Cleveland yesterday in the eruption party by ejecting a relatively small ash cloud and also a lava flow. Cleveland has been erupting or otherwise in a state of unrest for awhile now, this is new for Pavlof.

Elsewhere everything is pretty quiet except in Hawaii of course. Kilauea continues its extended eruption that has been in progress since 1983.

Alaskan Eruptions

PAVLOF VOLCANO (CAVW #1102-03-)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Following an increase in seismic activity and presence of intense elevated surface temperatures yesterday, eruptive activity at Pavlof has been confirmed. Pilot reports and satellite images today reveal that a spatter-fed lava flow has advanced about a half a kilometer down the north flank of the volcano. See an image at Alaska Volcano Observatory Images and Photos. Minor steam and ash emissions are visible at the summit from nearby Cold Bay.

CLEVELAND VOLCANO (CAVW #1101-24-)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Elevated surface temperatures continued at Cleveland Volcano over the past 24 hours. No explosions have been detected by regional infrasound data. Analysis of recent satellite imagery revealed a 100-m-wide lava flow, breaching the southeast rim of the summit crater, and extending about 1.5 km down the southeast flank.

I read someting yesterday about a volcano called Popo south east Mexico City. From what I understood, this volcano is showing signs of a possible eruption in the near future. Have you heard?

This might be a bit off subject(and a stupid question for some), but did all of those volcanos that erupted in 2008/2009 have anything to do with those cold winters we had shortly after? If I recall, there some pretty big eruptions in Iceland and the Philippine's that year. I believe, also one erupted in Chile.

Not sure. I'm sure they had some impact, but who knows how much.
