Officials from the U.S. Department of the Interior and United States Geological Survey have been touring sites in Mount Rainier National Park this week. They’re looking at five new locations where upgraded monitoring stations will soon enhance detection of lahars. There’s also a proposal to add another 12 lahar monitoring stations in the park, to complete an expansion they say will put detection at Rainier on par with other high-threat volcanoes in the region, such as Mount St. Helens.
