fault lines in new hampshire

Smaller extensions of the Ramapo Fault, including the Hopewell, Fleminton-Furlong, and Chalfont faults, are present within the basin. Schlische, R.W., 1992. The cooler rocks in the northeastern U.S. contribute to the seismic energy propagating as much as ten times further than in the warmer rocks of California. Paleozoic rock belts are also present in the area. [20] During this time, the Ramapo fault, originally a thrust fault active during the creation of the Appalachian Mountains, was reactivated as the Atlantic Ocean was opening and the supercontinent of Pangaea was being torn apart. The importance of linear shatter or rupture zones is becoming more appreciated as an earthquake trigger than in the past. [13][14], To the east of the Newark Basin are varying geologic provinces. A GIS database of geologic units and structural features in New Hampshire, with lithology, age, data structure, and format written and arranged just like the other states. $0.00. Some seismologists have argued that this fault has the potential to produce a major earthquake,[2][3] but earthquakes are scattered throughout this region, with no particular concentration of activity along the Ramapo fault. It is difficult to discern the extent to which the Ramapo fault itself (or any other specific mapped fault in the area) might be any more of a source of future earthquakes than any other parts of the region. In contrast, east of the Rocky Mountains this is rarely the case. Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its vicinity. [11], New Jersey, eastern Pennsylvania, and southeastern New York are divided geologically into four physiographic provinces, each distinctive in their structure. The New York City area is part of the geologically complex structure of the Northern Appalachian Mountains. Aggarwal, Y.P. 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. Structural and stratigraphic development of the Newark extensional basin, eastern North America: Evidence for the growth of the basin and its bounding structures. In 2011, a magnitude 5.3 quake hit Trinidad, Colorado, another … Product Tags. A magnitude 5.5 eastern U.S. earthquake, although uncommon, can be felt as far as 500 km (300 mi) from its epicenter, and can cause damage as far away as 40 km (25 mi) from its epicenter. Recently, public knowledge about the fault has increased, especially after the 1970s, when the fault's proximity to the Indian Point nuclear plant in New York was noted. A strike-slip fault is when two blocks slip past one another, like the San Andreas Fault line. Earthquakes stronger than about magnitude 5.0 generate ground motions that are strong enough to be damaging in the epicentral area. [11] Thus, earthquakes represent at least a moderate hazard to East Coast cities. The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east.
