article imageAlaskan volcano shoots ash plume 5 miles into the sky

By Leigh Goessl     Jun 27, 2013 in Science
A volcano located on the Alaskan peninsula is picking up in activity. Volcano Pavlof began rumbling in May, however, shot a 5-mile plume into the sky this week disrupting smaller aircraft which had to redirect to avoid the ash.
Pavlof, a stratovolcano located in Alaska's Aleutian range, is beginning to show an increased level of activity. A 5-mile high ash plume could be observed, reported NBC News.
Pavlof had begun to awaken from its slumber in May, spouting out lava, ash and steam, however, this week gained "new intensity" on Tuesday, reported Reuters. Seismic activity was the highest it has been all year.
An ash advisory was issued as cinders landed on a nearby town and interrupted local flights.
Experts said this activity is the strongest since the volcano began its wake-up in May.
"For some reason we can't explain, it picked up in intensity and vigor," said Tina Neal, an observatory geologist.

According to the Alaska Volcano Observatory (AVO), the volcano is currently on an Orange Alert Level (Watch).
An orange alert means a volcano is "exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain" or "eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible]."
The nearest town from Pavlof is approximately 25 miles away. The 8,261-foot (2,518-meter) high volcano is located 590 miles from Anchorage.
Two other volcanoes in Alaska are also rumbling. Veniaminof, which is located 485 miles southwest of Anchorage, has begun making some noise and the very remote Cleveland volcano has been erupting on and off since 2011, its strongest eruption occurring in early May. Currently, Cleveland is described by experts as "restless".
According to the Smithsonian Institute, Pavlof's last eruption was in 2007.
