When an eruption happens, scientists with the observatory use all their information streams to get warnings out. Their tools include seismometers planted into volcano flanks, satellites that send back infrared pixels of hotspots, GPS units that show volcanoes inflating like balloons, gas sensors that tell what is wafting from a crater, microphones on volcanoes that hear explosions, and rocks and ash collected from mountainsides.<\/p>\n\t\t\t\t
That’s a firehose of information, and scientists are happy to have it all. There is so much, though, that researchers rarely get to all of it before another eruption happens.<\/p>\n\t\t\t\t
A team of them will set up four Ph.D. students to dig into that data paydirt, to see if they can find a key to better eruption forecasts.<\/p>\n\t\t\t\t
Taryn Lopez is one of the scientists who is looking for those graduate students.<\/p>\n\t\t\t\t
“We’re pretty good at saying an eruption is going to happen,” she said of the current state of Alaska volcano monitoring. “We’re not so good at predicting how big it will be or how long it will last.”<\/p>\n\t\t\t\t
Lopez, an expert on volcanic gases at UAF’s Geophysical Institute, thinks students combing all this information on eight specific Alaska volcanoes might come up with something other busy people have missed.<\/p>\n\t\t\t\t
“If we put our tools together, we can say a lot more,” she said.<\/p>\n\t\t\t\t
She and her teammates on the project, including her husband David Fee, the coordinating scientist of the Alaska Volcano Observatory, have chosen eight Alaska volcanoes for a closer look. Four of them — Okmok, Bogoslof, Augustine and Redoubt — are the somewhat predictable big-mouth variety that tend to spew ash way up where jets are flying over the Great Circle Route.<\/p>\n\t\t\t\t
