The movement of Earth's viscous mantle against South America has pushed the Caribbean islands east over the last 50 million years, according to a study published Monday in the journal Nature ...

An entire series of earthquakes beginning with the Jan. 12 7.0 temblor in Haiti reflects the movement of the Caribbean plate eastward by about a couple of feet. A large number of aftershocks have ...

The concurrent subduction of the Pacific and Atlantic plates resulted in the formation of a mantle plum and the ascent of magma. Credit: Nicolas Riel Earthquakes and volcanism occur as a result of ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

Scientists have recently solved a longstanding mystery of the sea: It turns out that the smaller Caribbean islands are arranged in a crescent shape because of great geological forces - the hot viscous ...

Though we don't necessarily think of the Caribbean as earthquake country, it most definitely is. The earthquake that devastated Port-au-Prince on Tuesday occurred along the boundary of two tectonic ...

The worst quake – a magnitude 6.4 that struck early Tuesday – killed at least one person. Tectonics in Puerto Rico are dominated by the convergence between the North America and Caribbean tectonic ...

UPDATE: Also see this post from December 2009 of higher-resolution bathymetric images from the same region. I guess I'm feeling subductive this week (see Friday Field Foto #40). The bathymetric image ...
