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 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]
Mud volcanoes of the North American continent include: A field of small (<2 metres (6.6 ft) high) fault-controlled, cold mud volcanoes is on California's Mendocino Coast, near Glenblair and Fort Bragg, California. The fine-grained clay is occasionally harvested by local potters. [49]
A gaseous mud volcano. Evidence of geothermal activity is visible. The Salton Buttes are volcanoes in the geothermal field of the same name. Mudpots and mud volcanoes are found on the eastern side of the Salton Sea, [116] including the mobile Niland Geyser. [117]
The Niland Geyser is one of dozens of mudpots and mud volcanoes in the Salton Trough but is the only one in the world known to have moved significantly, affecting the Union Pacific Railroad, California State Route 111, and other infrastructure since 2018. [7] [8]
In 1934 a storm over the Southern California mountains unleashed runoff so intense that 30 people were killed, more than 480 homes were destroyed and a nearly 60-ton (54-metric ton) boulder was ...
Mt. Shasta, California's largest volcano, had many eruptions in prehistoric times but has remained quiet in the modern era. And like the Long Valley Caldera, the magma beneath Lassen Volcanic ...
Geologic map of the Sonoma Volcanics. The Sonoma Volcanics are a geologic formation of volcanic origin that is widespread in Napa and Sonoma counties, California.Most of the formation is Pliocene in age and includes obsidian, perlitic glass, diatomaceous mud, pyroclastic tuff, pumice, rhyolite tuffs, andesite breccias and interbedded volcanic lava flows.
