Some days have activity at about one tremor every minute. On October 2, 2009 there were three earthquakes, (5.2, 4.7, and a 4.9), all within one hour of each other. On July 4th and 5th, 2019 two large earthquakes sparked a surge of activity in the area in and around the Coso Volcanic Field. The first large quake on July 4 registered M6.4 and ...
The Long Valley Caldera, which includes Mammoth Lakes area, has been having seismic activity, which can precede a volcanic eruption. Scientists say not to worry. One of California's riskiest ...
Many geological features in Western United States have a Northeastern orientation, the North American craton motion has the same orientation as well. [1] For example: the Trans-Challis fault zone, Idaho; the Snake River in Oregon; the Garlock Fault, California; the Colorado River in Utah; the Colorado Mineral Belt; Crater Flat-Reveille Range-Lunar Crater lineament, the Northwestern Nevada ...
Some of these volcanic rocks bear traces of hydrothermal alteration. In some places the layers of volcanic rocks are as thick as 100 m (330 ft). [27] There may be other volcanoes buried in the sediment pile; [28] at least four separate aeromagnetic anomalies have been found at the Salton Buttes, and these may be signs of buried volcanoes.

One of the most active volcanoes in the world sits just a few hundred miles off the U.s. West Coast, and some scientists believe it’s only a matter of time before it erupts again – maybe even ...
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 ...
Southern California faces a risk of damaging debris flows this week, as a potentially strong atmospheric river is set to arrive in the region. L.A. prepares for debris flows, slides in major ...
The discovery of recent Holocene activity, which was initially assumed to have been protracted over time, has led to the California Volcano Observatory commencing volcano monitoring at the Ubehebe Craters, [8] including the installation of one seismometer. The volcano is classified as a "Moderate Threat" volcano in the USGS volcanic threat ...
