Examples of intraplate earthquakes include those in Mineral, Virginia, in 2011 (estimated magnitude 5.8), Newcastle, New South Wales in 1989, New Madrid in 1811 and 1812 (estimated magnitude as high as 8.6), [6] the Boston (Cape Ann) earthquake of 1755 (estimated magnitude 6.0 to 6.3), earthquakes felt in New York City in 1737 and 1884 (both ...
Minor earthquake activity that still continues in the area in the early 21st century may be a continuation of aftershocks. [7] With the development of earthquake studies and technology, this event has been extensively studied as an example of an intraplate earthquake. It is believed to have occurred on faults formed during the break-up of ...
Intraplate deformation is the folding, breaking, or flow of the Earth's crust within plates instead of at their margins. This process usually occurs in areas with especially weak crust and upper mantle, such as the Tibetan Plateau (Figure 1). Intraplate deformation brings another aspect to plate tectonic theory.
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.
Moderately damaging earthquakes strike between New York and Wilmington, Delaware, about twice a century, the USGS said, and smaller earthquakes are felt in the region roughly every two to three years.
The intraplate earthquake measured 7.6 on the moment magnitude scale and occurred at 17.4 km (10.8 mi) depth. [1] It had a maximum felt intensity of X (Extreme) on the Mercalli intensity scale. The earthquake killed at least 20,023 people (including 19 in southeastern Pakistan), injured another 166,000 and destroyed about 400,000 buildings. [4 ...
It is sometimes referred to (by, for example, publications from the USGS Earthquake Hazards Program) [1] as simply the southernmost portion of the neighboring Juan de Fuca plate, another Farallon remnant. Unlike most tectonic plates, the Gorda plate experiences significant intraplate deformation inside its boundaries.
Several key mistakes could throw off the accuracy of blood pressure readings for people who take them at home. The average "normal" blood pressure is 120/80, according to the American Heart ...
