The north-northwest end of the Walker Lane is between Pyramid Lake in Nevada and California's Lassen Peak [1] [2] where the Honey Lake Fault Zone, the Warm Springs Valley Fault, and the Pyramid Lake Fault Zone [3] meet the transverse tectonic zone forming the southern boundary of the Modoc Plateau and Columbia Plateau provinces.
The earthquake near Minnesota's western "bulge" is the Morris earthquake. This map and table shows where Minnesota's earthquakes have occurred. Earthquakes 1, 6, 9, 11, 15 and 18 are in the Great Lakes tectonic zone. The size of the dot indicates the strength of the earthquake. The Morris earthquake is No. 11.
Probabilistic seismic hazard map. The earliest known earthquake in the U.S. state of California was documented in 1769 by the Spanish explorers and Catholic missionaries of the Portolá expedition as they traveled northward from San Diego along the Santa Ana River near the present site of Los Angeles. Ship captains and other explorers also ...
The earthquake had a magnitude of 6.5 M L and a hypocentral depth of only 2.8 km (1.7 mi). Shaking was felt throughout California and Nevada, with some reports from as far as San Francisco, Los Angeles, and Salt Lake City. [7] [8] The estimated maximum intensity of shaking was rated as VIII (Severe) on the Modified Mercalli intensity scale.
Stretching for 250 kilometers (160 mi), it is the second-longest fault in California, and one of the most prominent geological features in the southern part of the state. It marks the northern boundary of the area known as the Mojave Block, as well as the southern ends of the Sierra Nevada and the valleys of the westernmost Basin and Range ...
A 5.8-magnitude earthquake hit Nevada Monday afternoon, according to the United States Geological Survey, with shaking felt as far west as California. The quake struck 15 miles north-northeast of ...
The probability of a serious earthquake on various faults has been estimated in the 2008 Uniform California Earthquake Rupture Forecast. According to the United States Geological Survey, Southern California experiences nearly 10,000 earthquakes every year. [3] Details on specific faults can be found in the USGS Quaternary Fault and Fold Database.
The earthquakes this week were located slightly north of the Ortigalita fault, in an area without any mapped fault lines at the surface, she said. “These earthquakes, of course, occurred some ...
