Mount Veniaminof volcano erupts in Alaska

A weak eruptive activity has started from the volcano. Since last night, weak ash emissions have appeared from the central cone of the caldera of the volcano. The new activity is accompanied by a persistent steam plume and increasing volcanic tremor. So far there seem to be no lava flows or other significant eruptive processes. The new ash emissions are very diluted and reach about 200-300 m height. They were first observed on the Aviation camera of Perryville from last night at around 17-18h local time. AVO who has not yet reported about the ash confirmed to Blog Culture Volcan that the plume indeed contains very small amounts of ash, which pose no problems to aviation (for now). The volcano last erupted in 2008. –Volcano Discovery

New volcanoes in Alaska discovered

Given their tendency to erupt, spewing out tons of molten lava and ash, it seems all the volcanoes in the world should have been discovered, cataloged, and researched by now. But in the past three years, U.S. Geological Survey geologists have discovered twelve new volcanoes in the southeastern region of Alaska, similar to the one pictured below.

The intrigue began in 2009, reports Live Science, when scientists discovered a volcano which erupted around the same time as Mt. Edgecumbe (the panhandle’s biggest volcano) that had a completely different chemical signature from its neighbor. With increased expeditions to the volcano came even more volcanic discoveries, all with a chemical pattern that turned out to be identical to that of the Northern Cordilleran Volcanic Province, a field of volcanoes in Canada already known to be 1,250 miles long and 375 miles wide. Those dimensions may now have to be revised.

A Blast of a Find: 12 New Alaskan Volcanoes

In Alaska, scores of volcanoes and strange lava flows have escaped scrutiny for decades, shrouded by lush forests and hidden under bobbing coastlines.

In the past three years, 12 new volcanoes have been discovered in Southeast Alaska, and 25 known volcanic vents and lava flows re-evaluated, thanks to dogged work by geologists with the U.S. Geological Survey (USGS) and the U.S. Forest Service. Sprinkled across hundreds of islands and fjords, most of the volcanic piles are tiny cones compared to the super-duper stratovolcanoes that parade off to the west, in the Aleutian Range.

The yet-to-be-named volcano in Southeast Alaska differs from many on the ocean floor. Its top was likely above the water when it last erupted some 10,000 years ago.

 

Jim Baichtal has a habit of cruising the website of the National Oceanographic and Atmospheric Administration looking for new hydrographic surveys of Alaska.

“I was just checking the website before I headed out one day," he said, "and when I saw the survey results of an area near Ketchikan, all I can remember saying is, ‘Oh, my gosh!’" Buried inside the NOAA data were 3D renderings of a previously unknown volcano, beneath the depths of Behm Canal inside Misty Fjords National Monument.

The yet-to-be-named volcano differs from many on the ocean floor. Baichtal, a U.S. Forest Service geologist, says its top was likely above the water when it last erupted some 10,000 years ago. NOAA imaging and new underwater video of the area shows what appears to be leftovers of ash or cinder near the volcano crater.
