| In May 1915, Lassen Peak, California, the southern-most active volcano in the Cascade Range, erupted explosively. Avalanches, mudflows, and flows of hot ash and gas devastated nearby areas, and volcanic ash fell as far away as 200 miles to the east. The Lassen area remains volcanically active, and the volcano hazards demonstrated in 1915 still can threaten not only nearby areas but also more distant communities. Recent work by scientists with the U. S. Geological Survey (USGS) in cooperation with the National Park Service is shedding new light on these hazards. -- Clynne, et.al., 2000, USGS Fact Sheet 022-00 |
