The United States Geological Survey National Volcanic Threat Assessment is a report containing a ranked list of active volcanoes in the United States posing hazardous risks to the American population. [1] The report was published by the United States Geological Survey in 2005 [2] and revised in 2018. [3]
Younger volcanoes that erupted after passing over the hotspot covered the plain with young basalt lava flows in places, including Craters of the Moon National Monument and Preserve. The central Snake River plain is similar to the eastern plain, but differs by having thick sections of interbedded lacustrine (lake) and fluvial (stream) sediments ...

Trident Volcano is an eroded volcanic complex on the Alaska Peninsula in Katmai National Park, Alaska. Up to 23 domes comprise the complex stratovolcano, with the greatest elevation of 6,115 feet (1,864 m). The most recent major activity produced a 3,599-foot (1,097 m) dome in an amphitheater on the southwest flank of the southwest peak.
The southern and eastern sides of the volcano drain into an upstream impoundment, the Swift Reservoir, which is directly south of the volcano's peak. Although Mount St. Helens is in Skamania County, Washington, access routes to the mountain run through Cowlitz County to the west, and Lewis County to the north.
