Niland Geyser (nicknamed the "Slow One" [2] and formally designated W9) [3] is a moving mud pot or mud spring outside Niland, California in the Salton Trough in an area of geological instability due to the San Andreas Fault, [4] formed due to carbon dioxide being released underground. It is the only mud pot or mud volcano known to have moved so ...
The region on the volcano's northeastern flank destroyed by the eruptions, 3 sq mi (7.8 km 2) in area, is now known as the Devastated Area, and it along with other deposits from the volcano has been altered by erosion and regrowth of vegetation, [73] though the vegetation in Devastated Area is sparse due to its siliceous (rich in silica ...
The magma that fuels the volcanoes in the park is derived from subduction off the coast of Northern California. Cinder Cone and the Fantastic Lava Beds , located about 10 mi (16 km) northeast of Lassen Peak, is a cinder cone volcano and associated lava flow field that last erupted about 1650.
[1] [28] Known as the Loomis Sequence, [28] these pre-Lassen dacites are the black, glassy, columnar lavas that now surround Lassen Peak. [11] Aquamarine water pool in the Bumpass Hell hydrothermal area. Sometime between 25,000 and 31,000 years ago, Lassen Peak, a Pelean lava dome volcano, was pushed up through the pre-Lassen dacites.

For years now, California has been bracing for the "big one" -- the magnitude 6.7 or greater earthquake that is expected to send ripples through the state within the century. But there's another ...
The Salton Buttes lie on the southeastern shores of the Salton Sea, with their peaks at an elevation of −40 m (−130 ft), [1] in Imperial County, California. [2] [3] The towns of Niland and Calipatria lie northeast and southeast of the Salton Buttes, respectively, [4] and Palm Springs is 140 kilometers (90 mi) northwest. [5]
And it could contaminate water supplies to much of the state (California’s largest reservoirs are close to the Shasta and Lassen volcanoes). Mt. Shasta, California's largest volcano, had many ...
