On October 23, 2002, there was a magnitude 6.7 earthquake located on the Denali fault. The event's aftershocks revealed a 45 km (28 mi) long fault rupture along the Denali fault, but aerial reconnaissance could not locate a surface rupture. This rupture extends to 10 km (6.2 mi) west of the mainshock's epicenter.
It was the main fault along which the 2002 Denali earthquake occurred, which was measured as a magnitude of 7.9 M w. [8] During the afternoon of November 3, 2002, the water in Seattle's Lake Union suddenly began sloshing hard enough to knock houseboats off their moorings.
The 7.9-magnitude 2002 Denali earthquake struck the region in November 2002. The earthquake initiated with thrust movement on the previously unrecognized Susitna Glacier fault. [2] Aerial view of Susitna Glacier flowing from Moby Dick mountain
The Totschunda Fault is a major active dextral (right-lateral) continental strike-slip fault in southeastern Alaska. It forms a link between the Denali Fault to the northwest and the Fairweather Fault to the southeast. The northwestern end of the fault ruptured during the 2002 Denali earthquake. [1]
Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen .
The second type of tremor has been detected worldwide; for example, it has been triggered in the San Andreas Fault by the 2002 Denali earthquake and in Taiwan by the 2001 Kunlun earthquake. [ 20 ] [ 21 ]
