The United State Geological Survey ranks many volcanic regions of the West Coast’s Cascade Range as “High Priority” in need of monitoring, including California’s Clear Lake Volcanic Field, Mono-Inyo Craters, Mono Lake Volcanic Field, Medicine Lake.
The California observatory lists those and other volcanoes in the region into three categoriesVery-high threat: Mount Shasta, Lassen Volcanic Center and Long Valley Volcanic RegionHigh threat: Clear Lake Volcanic Field, Medicine Lake Volcano and Salton ButtesModerate threat: Ubehebe Crater and Coso Volcanic Field
In 2005, a national team led by John Ewert, a volcanologist with the USGS Cascades Volcano Observatory, established a system for deciding which of the United States’ 169 young volcanoes are the most dangerous and most in need of monitoring. In the “Framework for a National Volcano Early Warning System,” Ewert’s team identified 57 priority volcanoes in the U.S.
Among the report’s 18 “very high threat volcanoes” are California’s Lassen Volcanic Center, Long Valley Caldera, and Mount Shasta.
Lassen Peak was the most recent volcano to erupt in the state (1914-1917), and volcanologists say it will happen again, possibly in our lifetime.Read more at TheFederalistpapers
