Schlesinger-Miller, and N.L. Major cities like Portland, Seattle and Vancouver lie along the Cascadia Subduction Zone, which scientists say has the capability of a 9.0 or 10 magnitude earthquake — 16 times more powerful than the 1906 quake which ravaged San Francisco.

The quake was the strongest earthquake to hit the East Coast. E.A. In southeastern New York, from With initial activity in the Late Precambrian – Early Paleozoic age, specifically the Cambrian-Despite the rarity of strong East Coast earthquakes in the United States, they do sometimes occur. This is why earthquakes in the East are relatively uncommon and weaker in … The northern fault then fully developed and became the Highland Boundary Fault Line. It’s one of the biggest fault lines in the world scarring a huge part of an Australian state — and it has the potential to cause havoc. Many of the older structures in the East, such as … However, a In 2011, a magnitude 5.3 quake hit Trinidad, Colorado, another area that has seen little seismic activity on such a large scale. Location: Epicenter at 39.178, -73.725. In the case of the 2011 earthquake, scientists knew it originated in the Central Virginia Seismic Zone, but it didn’t line up with any previously mapped faults. We've received your submission. Geologists across the country can use the data to better understand why earthquakes like the one in 2011 are felt so far afield.“It seems that these eastern-originating earthquakes tend to ring the entire East Coast like a bell,” Witt said.In the case of the 2011 earthquake, scientists knew it originated in the Central Virginia Seismic Zone, but it didn’t line up with any previously mapped faults.“In 2011, we thought we had pretty good mapping of where two major faults ran through the Central Virginia zone, and that earthquake actually occurred between them,” Virginia State Geologist David Spear said.In order to better understand these seismic zones and their related hazards, the Division of Geology and Mineral Resources is participating in a project funded by the Federal Emergency Management Agency and the Virginia Department of Emergency Management. Armbruster, W.Y. The 5.8 magnitude earthquake that struck the commonwealth in 2011 was a wake-up call for many Virginians. The Ramapo Fault forms the boundary between the Newark Basin and the Highlands, running from To the east of the Newark Basin are varying geologic provinces. Furthermore, when these rare eastern U.S. events do occur, the areas affected by them are on average ten times as large as western ones for events of the same magnitude.Earthquakes in the greater New York City area affect most of New Jersey, Just off the northern terminus of the Ramapo fault is the Aggarwal, Y.P. As in most other areas east of the Rocky Mountains, the best guide to earthquake hazard in the northeastern U.S. is probably the locations of past earthquakes themselves. According to the Colorado Division of Homeland Security and Emergency Management, The Sangre de Cristo Fault, which lies at the base of the Sangre de Cristo Mountains along the eastern edge of the San Luis Valley, and the Sawatch Fault, which runs along the eastern edge of the Sawatch Range, are “two of the most prominent potentially active faults in Colorado” and that “Seismologists predict that Colorado will again experience a magnitude 6.5 earthquake at some unknown point in the future.”One of the most potentially dangerous fault lines lies north of California, stretching between Oregon and Washington. Sykes (1978), Earthquakes, faults and Nuclear Power Plants in Southern New York and Northern New Jersey, Science, 200, 425–429.Sykes, L.R., J.G. The fault is invisible from the surface, but magnetic surveys from the air see it clearly, represented in the white line. Winslow, and N.L. “With time we hope to identify more faults and have better data to provide to state and local planners.” “Identifying faults is easier in the West because the landscape is younger and the faults can be more apparent.”By combing through historic data in written records and geologic indicators of prehistoric earthquakes, scientists have been able to identify three major “seismic zones” where many earthquakes appear to originate in Virginia.The Central Virginia Seismic Zone stretches from Richmond to Charlottesville and encompasses much of the Piedmont. 60.2 km from Brigantine (37.2 miles) East Coast Of United States. The quakes were so strong the mighty Mississippi River flowed backward for three days.
