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. However, since the rules of the game are not well understood in this area, it is hard to forecast the hazard. Retrieved from internet 9-30-2004; < The Ramapo Fault, a New York Metro-area fault line, runs 70 miles through New Jersey, New York and Pennsylvania. Armbruster, W.Y. Pennsylvania Bureau of Topographic and Geologic Survey, Department of Conservation and Natural Resources, 2001, Bedrock Geology of Pennsylvania, edition: 1.0, digital map. Some seismologists have argued that this fault has the potential to produce a major earthquake,Earthquake rates in the northeastern U.S. are 100 times lower than in California, but the earthquakes that do occur in the northeastern U.S. are typically felt over a much broader region than earthquakes of the same magnitude in the western U.S.The northeastern U.S. has many known faults, but numerous smaller or deeply buried faults probably remain undetected. Schlesinger-Miller, and N.L. 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.East of the Highlands is the Piedmont, specifically the Newark Basin. Pennsylvania, United States has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 0 earthquakes in the past 7 days; 2 earthquakes in the past 30 days The Everett Gap fault terminates westward with the Hartley thrust fault.

E.A. 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. Winslow, and N.L. 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. Preliminary integrated geologic map databases for the United States : Delaware, Maryland, New York, Pennsylvania, and VirginiaMethods used to create several styles for lithology or geologic timeBerg, T. M., Edmunds, W. E., Geyer, A. R., and others, compilers, 1980, Geologic map of Pennsylvania: Pennsylvania Geological Survey, 4th ser., Map 1, 2nd ed., 3 sheets, scale 1:250,000.

Structural and stratigraphic development of the Newark extensional basin, eastern North America: Evidence for the growth of the basin and its bounding structures. Given the current geological and seismological data, it is difficult to determine if a known fault is still active today and could produce a modern earthquake. A GIS database of geologic units and structural features in Pennsylvania, with lithology, age, data structure, and format written and arranged just like the other states.
Farther west, the Bedford fault extends westward to terminate against the Wills Mountain thrust fault. Pennsylvania geologic map data A GIS database of geologic units and structural features in Pennsylvania, with lithology, age, data structure, and format … Virtually all of the known faults have not been active for perhaps 90 million years or more. and L.R. Also, the locations of the known faults are not well determined at earthquake depths. The fault has been quiet for about 200 years and it is sure that at some point an earthquake is going to occur. Everett, Pennsylvania, the Breezewood fault terminates with the Ashcom thrust fault. Accordingly, few earthquakes in the region can be unambiguously linked to known faults. these are the faults that occur in transmission line: 1. line to line fault 2. line to ground fault-this is the most common fault that occurs in tr.
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.
