In the last 8,000 years, the Hotlum Cone has erupted at least eight or nine times. About 200 years ago, the last significant Mount Shasta eruption came from this cone and created a pyroclastic flow, a hot lahar (mudflow), and three cold lahars, which streamed 7.5 mi (12.1 km) down Mount Shasta's east flank via Ash Creek. A separate hot lahar ...
Shastina is a satellite cone of Mount Shasta. It is the second youngest of four overlapping volcanic cones which together form the most voluminous stratovolcano in the Cascade Range . At 12,335 feet (3,760 m), Shastina is taller than Mount Adams and would rank as the third highest volcano in the Cascades behind Mount Rainier and Shasta were it ...
Map of Lassen Volcanic National park Mount Shasta from Lassen Peak Painted Dunes and Fantastic Lava Beds as seen from the edge of Cinder Cone's crater. Lassen Volcanic National Park is a national park of the United States in northeastern California.
The volcanoes with historical eruptions include: Mount Rainier, Glacier Peak, Mount Baker, Mount Hood, Lassen Peak, and Mount Shasta. Renewed volcanic activity in the Cascade Arc, such as the 1980 eruption of Mount St. Helens, has offered a great deal of evidence about the structure of the Cascade Arc. One effect of the 1980 eruption was a ...

An eruption as large as Mount Pinatubo in 1991 could certainly cool the planet for a few years, though it wouldn’t be able to erase the Earth’s current climate woes caused by planet-warming ...
