Tectonic map of Alaska and northwestern Canada showing main faults and historic earthquakes Denali Fault and the Denali National Park boundary. The Denali Fault is a major intracontinental dextral (right lateral) strike-slip fault in western North America, extending from northwestern British Columbia, Canada to the central region of the U.S. state of Alaska.
The Denali-Totschunda fault is a major dextral (right lateral) strike-slip system, similar in scale to the San Andreas Fault system. In Alaska, moving from east to west, the plate interactions change from a transform boundary between the Pacific plate and North American plate to a collision zone with a microplate, the Yakutat terrane, which is in the process of being accreted to the North ...
To the west, the Denali Fault is the source of minor earthquakes that extend along the length of the fault. [11] In contrast to the Tintina Fault, strike-slip movement along the Denali Fault has offset at least 370 km (230 mi) of the surface. [11] The fault separates mountains of the Insular Belt from mountains east of the fault. [11]
The map and accompanying study offer precise information about the regions most at risk of earthquakes, and which types of quakes are likely to occur. ...
Locations of quakes magnitude 2.5 or greater in the Wabash Valley (upper right) and New Madrid (lower left) Seismic Zones. The Wabash Valley seismic zone (also known as the Wabash Valley fault system or fault zone) is a tectonic region located in the Midwestern United States, centered on the valley of the lower Wabash River, along the state line between southeastern Illinois and southwestern ...
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
The Salcha Seismic Zone is a fault line in the Interior region of Alaska, United States, generally located to the east of Fairbanks.The fault runs for 65 km (40 mi) from the northern edge of the Alaska Range across the Tanana Valley to the southern end of the Yukon–Tanana Uplands and is parallel to the Fairbanks and Minto Seismic Zones located further west.
