Geo faculty Erik Klemetti comments on active Mexican volcano

Faculty

A volcano in Colima, Mexico, sent an ash column about 29,000 feet into the air. Geosciences faculty Erik Klemetti expounds on the processes behind this stunning natural event in a Yahoo News article with accompanying video.

According to the article:

“Erik W. Klemetti, a volcanologist in Denison University’s geosciences program, explains that the Colima volcano shoots out sticky lava when gases trapped inside new magma collect, causing pressure to build in the vent.

” ‘It’s sort of like popping a champagne cork once that pressure is released,” Klemetti said in an interview with Yahoo News. “All the bubbles popping in the magma are enough to create that huge column of ash.’

“A small pyroclastic flow — or quick current of hot gas and rock — traveled down the mountain’s steep slope, according to Volcano Discovery.”
