Charleston, SC Earthquake – 1886. South Carolina earthquakes occur with the greatest frequency along the central coastline of the state, in the Charleston area. South Carolina is the most seismically active state on the east coast. [1] At 7.3 magnitude, the Charleston earthquake of 1886 was the largest quake to ever hit the Eastern United ...
Photographic evidence of the South Carolina Railroad southeast of Summerville also showed a right-lateral offset of 4.5 ± 0.3 m (14.76 ± 0.98 ft) on the track. Direct observation of the earthquake's effects also reported the rail bed being "forced to the right", supporting the identification of this offset.
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
This once-active divergent plate boundary became the passive, trailing edge of westward moving North America. In plate tectonic terms, the Atlantic Plain is known as a classic example of a passive continental margin. [20] During the rifting, South America tore away from North America and headed southward.
The South American plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African plate, with which it forms the southern part of the Mid-Atlantic Ridge.
