Strong northwesterly winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes have picked up loose volcanic ash eruption and carried it to the southeast toward Kodiak Island today. The maximum cloud height is 5,000 ft above sea level. This is not the result of recent volcanic activity and occurs during times of high winds and dry snow-free conditions in the Katmai area.

The pumice blob has the potential to deposit new, healthy coral around the badly damaged Great Barrier Reef, scientists say.

"Since the last eruption event, most seabird species that previously nested on the island have returned and made attempts to breed again...but the habitat is currently not ideal."

Shishaldin Volcano also erupted last month, sending ash over the Bering Sea.

Unlike some of its perpetually active neighbors on the Kamchatka Peninsula, Raikoke Volcano on the Kurile Islands rarely erupts. The small, oval-shaped island most recently exploded in 1924 and in 1778.

Shiveluch volcano (Kamchatka) in Kamchata is erupting. Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 33000 ft (10100 m) altitude or flight level 330 and is moving at 55 kts in S direction.

Shishaldin Volcano is spewing ash up to 27,000 feet in sky, leading to flight cancelations.
