The Ramapo Fault has been blamed for several past earthquakes, but the specific association of any significant earthquake with this fault has yet to be demonstrated. [6] A damaging earthquake affecting New York City in 1884 was incorrectly argued to be caused by the Ramapo fault, likely because it is the most prominent mapped fault in the ...
These lines allow tectonic plates to move and earthquakes occur when two plates slide past each other. The Ramapo Fault System is the longest in the northeastern U.S., stretching from Pennsylvania ...
While earthquakes are most common along the fault lines of tectonic plates—of which there are seven major ones in the world—the seismic quakes can actually hit anywhere, at any time, according ...
Thrust fault: Active: 2008 Sichuan (M8.0) Lost River Fault: Idaho, United States: Normal: Active: 1983 Borah Peak (M6.9) Lusatian Fault: Germany: Thrust fault: Macquarie Fault Zone >400: South Pacific Ocean: Fault (geology)#Strike-slip faults: Active: 1989 Maquarie Isl. (8.2), 2008 Macquarie Island earthquake (M7.1) Mae Chan Fault: 120 ...
The earthquake's epicenter was in the Southern Great Lakes seismic zone, about 25 kilometers (16 mi) southwest of Meadville; its depth was 5 kilometers (3 mi).The earthquake caused minor damage in towns near its epicenter and was felt in the states of Ohio, Pennsylvania, Indiana, Michigan, New York, Illinois and New Jersey, as well as Southern Ontario in Canada.
A magnitude 4.8 earthquake shook the East Coast shortly after 10:20 a.m. Friday morning, according to the United States Geological Survey. (USGS)
The top plate illustrates the tectonic setting for the sediments of Pennsylvania. This section is characterized by the metamorphic rocks that provide much of the bedrock for this area. The oldest exposed rocks in Pennsylvania are found here and consist of the Baltimore Gneiss. [8] These rocks have a complex history and a vast array of different ...
In this case, the earthquake can be confidently associated with the plane dipping shallowly to the northeast, as this is the orientation of the subducting slab as defined by historical earthquake locations and plate tectonic models. [3] Fault plane solutions are useful for defining the style of faulting in seismogenic volumes at depth for which ...
