English: Hazard map around the Mount Rainier, state of Washington, United States. Lava flow and pyroclastic flows Electron Mudflow-sized event (generally large in size)
Hazard map. Mount Rainier is a stratovolcano in the Cascade Volcanic Arc that consists of lava flows, debris flows, and pyroclastic ejecta and flows. Its early volcanic deposits are estimated at more than 840,000 years old and are part of the Lily Formation (about 2.9 million to 840,000 years ago).
Detailed map of Mount Rainier's summit and northeast slope showing upper perimeter of Osceola collapse amphitheater (hachured line) The Osceola Mudflow, also known as the Osceola Lahar, was a debris flow and lahar in the U.S. state of Washington that descended from the summit and northeast slope of Mount Rainier, a volcano in the Cascade Range during a period of eruptions about 5,600 years ago.
Mount Adams was last active about 1,000 years ago and has created few eruptions during the past several thousand years, resulting in several major lava flows, the most notable being the A. G. Aiken Lava Bed, the Muddy Fork Lava Flows, and the Takh Takh Lava Flow. One of the most recent flows issued from South Butte created the 4.5-mile (7.2 km ...
Map of hazards from the Three Sisters showing risk of lava flows and lahars in the immediate area Neither North nor Middle Sister is likely to resume volcanic activity. [ 60 ] An eruption from South Sister would pose a threat to nearby life, as the proximal danger zone extends 1.2 to 6.2 mi (2 to 10 km) from the volcano's summits. [ 69 ]
A hiker was rescued Sunday from an Oregon state park where she had been missing almost two full days, the U.S. Coast Guard said. The 64-year-old woman's calls for help caught the attention of ...
The Cascades extend northward from Lassen Peak (also known as Mount Lassen) in northern California to the confluence of the Nicola and Thompson rivers in British Columbia. The Fraser River separates the Cascades from the Coast Mountains in Canada, [4] as does the Willamette Valley from the upper portion of the Oregon Coast Range.
The dramatic rescue unfolded at 10 a.m. Friday, Feb. 3, at the mouth of the Columbia River in 30-foot swells, McClatchy News reported. (1/4) #BreakingNews - Talk about arriving in the nick of time!
