Redoubt Volcano (Alaska) erupted 26 years ago this week, with eruptions continuing into June of 1990. Here is a fixed wing fly-by of the volcano, including a tipped wing look down into the crater, taken during an eruption on January 14, 1990. The video is from the Alaska Volcano Observatory archives. #usgs #avo #alaskavolcanoobservatory #volcanoes #redoubt #geology | USGS Volcanoes

Many flights between the U.S. and Asia go over Alaskan volcanoes. Here's a look inside the USGS Alaska Volcano Observatory, where researchers are keeping track of "explosive" volcanic eruptions. http://cnn.it/1SrWkSe | CNN International
