Satellite and webcam footage revealed small deposits of ash near the summit, but the ash cloud stayed below 10,000 feet.

On this day in 1989, Redoubt eruption triggered seismic shift in Alaska volcano research
When Redoubt erupted in 1989, the Alaska Volcano Observatory was just one year old and relayed information by fax machine and floppy disk. Today AVO uses an array of sensors, receivers and satellites to monitor dozens of Alaska volcanoes, including Redoubt.
A string of volcanoes in the Aleutian Islands might actually be one mega volcano, scientists say
Multiple pieces of evidence led scientists to the conclusion that there might be a 12-mile-wide caldera — a large volcanic crater — or a number of calderas, hidden underwater beneath the group of islands.
6.2 magnitude earthquake felt in Adak
The Alaska Earthquake Center says there have been dozens of aftershocks since the Wednesday night quake in the Aleutian Islands. There is no tsunami threat expected.
Unrest at Aleutian volcano increases, triggering aviation warnings
Ash eruption at Shishaldin Volcano in the Aleutian Islands has intensified, sending an ash cloud 27,000 feet in the air.
After a huge eruption of ash, Mount Veniaminof quiets down
Mount Veniaminof has stopped spewing ash for now. Located on the Alaska Peninsula north of Perryville, the volcano emitted a large ash cloud last week that narrowly missed the village.
Yes, Alaska’s volcanoes still dominate in updated threat assessment
The U.S. Geological Survey released an update last week to its volcano threat assessment that placed five Alaska volcanoes in the “very high threat” category, more than any other state. Michelle Coombs, scientist in charge at the Alaska Volcano Observatory, explains what determines those rankings.
Cash from Congress will boost Alaska-based system that protects planes from volcanic ash
A $12 million budget boost from Congress will help modernize the instruments that protect transcontinental jet planes from threats posed by volcanic ash.
New lava dome forms on Cleveland Volcano
Scientists at the Alaska Volcano Observatory observed that a new lava dome formed in the summit crater over the weekend, and lava is trickling out. The dome is about 4,200 square meters, a little smaller than 10 NBA basketball courts.
Three Alaska Peninsula volcanoes are restless
Bogoslof volcano has a new lava dome. Cleveland volcano continues to put up ash and extrude lava, and the alert level for Pavlof volcano was raised to “advisory.”
