The 1993 Scotts Mills earthquake, also known as the "Spring break quake", occurred in the U.S. state of Oregon on March 25 at 5:34 AM Pacific Standard Time. With a moment magnitude of 5.6 and a maximum perceived intensity of VII ( Very strong ) on the Mercalli intensity scale , it was the largest earthquake in the Pacific Northwest since the ...
The tremors during the September 1993 Klamath Falls earthquakes were some of the strongest felt in Oregon's history over the past 50 years. [6] The first shock was only 4.2 M w. [3] The two major quakes, which measured 5.9 and 6.0, were, up to that point in Oregon's history, the strongest recorded earthquakes and resulted in the most damage. [7 ...
The epicenter was in the southern Puget Sound, northeast of Olympia, but the shock was felt in Oregon, British Columbia, eastern Washington, and Idaho. [6] This was the most recent of several large earthquakes that occurred in the Puget Sound region over a 52-year period and caused property damage valued at $1–4 billion.
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.
Thanks to the Great Oregon ShakeOut drill, earthquakes are top of mind for Oregonians, but why should we prepare? Frequently asked questions about Oregon quakes.
A 6.1 magnitude earthquake occurred approximately 173 miles off the coast of Bandon, Ore. at approximately 1:15 p.m. Wednesday, according to the U.S. Geological Survey.
Damaging earthquakes are well known in the Pacific Northwest, including several larger than magnitude 7, most notably the M9 1700 Cascadia earthquake and the M7.0–7.3 earthquake in about 900AD on the Seattle Fault. The M6.5 1965 Puget Sound earthquake shook the Seattle, Washington, area, causing substantial damage and seven deaths. This event ...
These earthquakes are sometimes referred to as crustal earthquakes, and they are capable of causing significant damage due to their relatively shallow depths. A damaging magnitude 7 interplate earthquake occurred on the Seattle Fault around 900–930 CE [14] that generated 3 meters of uplift and a 4-5 meter tsunami. [15]
