This zone of intense earthquake activity is located deep within the interior of the North American plate. An intraplate earthquake occurs in the interior of a tectonic plate, in contrast to an interplate earthquake on the boundary of a tectonic plate. [1] [2] They are relatively rare compared to the more familiar interplate earthquakes.
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.
Induced seismicity, typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth's crust. [10] Interplate earthquake, an earthquake that occurs at the boundary between tectonic plates. [11] Intraplate earthquake, an earthquake that occurs within the interior of a tectonic plate. [12 ...
Interplate earthquakes associated at a subduction boundary are called megathrust earthquakes, which include most of the Earth's largest earthquakes. [2] Intraplate earthquakes are often confused with interplate earthquakes, but are fundamentally different in origin, occurring within a single plate rather than between two tectonic plates on a ...
A major earthquake measuring 7.4 hit Taiwan early Wednesday, killing 9 and injuring at least 1,000. A 7.4 earthquake is exponentially more destructive than the 4.8 quake that struck central New ...
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.
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 ...
These big earthquakes near Tennant Creek occurred in the Proterozoic North Australian Craton, approximately 1500 km further south than the nearest plate boundary, therefore these events are referred to as intraplate earthquakes. The area where the quakes struck had no history of any earthquake before 1986 compared to the other seismic zones ...
