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.
1138 Aleppo earthquake: Delfi Fault Zone: 25: Central Greece: Normal to strike-slip: Denali Fault ... Queen Charlotte-Fairweather Fault: 800: Canada and Alaska ...
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.
March 27, 1964 Alaska earthquake: Lasting four minutes and thirty-eight seconds, the magnitude 9.2 megathrust earthquake remains the most powerful earthquake recorded in North American history, and the second most powerful earthquake recorded in world history. Nine hundred and seventy kilometres (600 mi) of fault ruptured at once and moved up ...
Tremor and slow-slip earthquakes have also been observed in the Aleutian subduction zone. [2] The low frequency earthquake (LFE) hypocenters associated with these processes are located near Kodiak Island, Shumagin Gap, Unalaska, and the Andreanof Islands, down-dip of these great megathrust events, where the two converging plates are thought to ...
Tectonic map of Alaska and northwestern Canada showing main faults and historic earthquakes. The Queen Charlotte Fault is an active transform fault that marks the boundary of the North American plate and the Pacific plate. [1] [2] It is Canada's right-lateral strike-slip equivalent to the San Andreas Fault to the south in California. [3]
Map of the Earthquakes At Yakutat Bay showing measurements, change of level, and inferred fault lines. Field investigations by members of the US Geological Survey in subsequent years found evidence of substantial changes in ground level in the affected areas, mostly uplift. The evidence was of several types: physiographic, such as elevated sea ...
The Alaska earthquake was a subduction zone (megathrust) earthquake, caused by an oceanic plate sinking under a continental plate. The fault responsible was the Aleutian Megathrust, a reverse fault caused by a compressional force.
