The Caribbean plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the northern coast of South America. Roughly 3.2 million square kilometres (1.2 million square miles) in area, the Caribbean plate borders the North American plate, the South American plate, the Nazca plate and the Cocos plate.
This paradoxically results in divergence which was only incorporated in the theory of plate tectonics in 1970, but still results in net destruction when summed over major plate boundaries. [2] Divergent boundaries are areas where plates move away from each other, forming either mid-ocean ridges or rift valleys. These are also known as ...
The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States.
Here's what causes the geologic phenomenon. ... But on the East Coast, the nearest plate boundaries are in the center of the Atlantic Ocean, making it harder to study the area. ... It is possible ...
Tectonic plate boundaries, showing the directions of plate movements. Different kinds of boundaries. The different ways in which tectonic plates rub against each other under the ocean or sea floor to create submarine earthquakes. The type of friction created may be due to the characteristic of the geologic fault or the

The notices advised residents a tsunami could arrive along the coast starting near Fort Bragg at 11:10 a.m. local time and move along the coast in northern California and southern Oregon, arriving ...
Tectonic and seismic map of Puerto Rico Trench area. Arrows show direction of plate movements. USGS. On 11 October 1918, the western coast of Puerto Rico was hit by a major earthquake which caused a tsunami. The 1918 earthquake was caused by an old left-lateral strike-slip fault near the Mona Passage.
