On Friday, August 2, Volcanologist Tina Neal talked about her exciting job monitoring Alaska's volcanoes in the Alaska Volcano Observatory.
Volcanoes are monitored with placed around the surface of the volcano. There are three to five seismometers per volcano and the Alaska Volcano Observatory monitors 27 volcanoes. The seismometers locate tremors by triangulation and map out the volcano's activity.
The biggest volcano threat in Alaska is ash. About 10 to 12 days a year there are ash warnings for commercial airlines because the ash reaches 25,000 feet.
