Aleutian volcanoes continue to cause problems - The ash cloud from Kasatochi Volcano has drifted over 1650 miles into the flight paths of aircraft in Anchorage and caused more than 50 flight cancellations Sunday and Monday. The oval shaped ash cloud was 300 miles at its widest point and moving around 39,000 to 40,000 feet in the air. This is an old ash cloud emitted during the initial eruption last Thursday. The ash might cause more delays over the next few days. Kasatochi may not be through erupting. "Our opinion is that it's still a restless volcano and it would not be a big surprise if we saw some more activity out at Kasatochi." They don't expect more large earthquakes in the region like were experienced last week. "That was VERY UNUSUAL. It's typically PRETTY RARE to see earthquakes that big associated with a volcano. We typically don't see that kind of seismic intensity."
Mount Cleveland also seems to be perking up again. AVO raised the volcano from yellow to orange Monday afternoon because of satellite images of new lava at the summit. "A lot of times when Cleveland produces a strong thermal anomaly at the summit, it's sometimes followed by an explosive ash emission. Sometimes these ash emissions can go high, above 30,000 feet."
Okmok is also at orange. Penair representatives say they are monitoring ash from all three volcanoes to see when they can resume flights to Nikolski and Atka.
