...Jindal, Gov. Bobby • anti-volcano-monitoring stance of looks even stupider after repeated eruptions of Alaska's Mount Redoubt...
...steamy antipodean evening, and I'm lost in the Australian bush, wandering around a remote patch of Queensland that is the last redoubt of one of the world's rarest large mammals: the northern hairy-nosed wombat. Only 115 of the burrowing, nocturnal marsupials survive in this 7,800-acre (3,160 hectare) preserve at Epping Forest National Park, and I've ventured out in the hope of spotting one. As my footsteps send wallabies bounding through the scrub, something shuffles through the grass a few yards ahead. I aim my flashlight, and I'm startled to find myself confronting...
...walk you through what's happening at our Alaska volcano observatory, one of five in the country. [The others are in Yellowstone National Park, Washington State, Hawaii, and Long Valley, California.] We have seismic networks and other geophysical equipment monitoring a number of volcanoes in Alaska, including Redoubt Volcano, 100 miles southwest of Anchorage. The volcano is showing a lot of signs of unrest that probably presage an eruption. So we look at seismic data, webcams, radar data and satellite imagery; we make overflights in airplanes to observe; we take gas measurements. We try to pull all this information together...
...precise can you be with your forecasting? Once the volcano starts erupting, we get better and better. An eruption is usually episodic - there's some activity, then a pause. The hard part is pinpointing where it first starts up. We use a graduated alert system. Right now, Redoubt Volcano is at orange. At orange, the military might move some planes out of a vulnerable airport. I read that trucking companies are buying ash filters. When it's red, we hope to give them hours of warning...
...magma. Since the magma has to make space for itself as it rises, the surface of the volcano deforms and we can look for those deformations. Then that gas makes its way out of the ground into the atmosphere, and we can measure it there. At Redoubt, for example, it's melting glacial features. We have to put all of this together and make an estimate. (See pictures of the world's eight new natural wonders...
