Tectonic Shoving Match Formed Caribbean Island Arc
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 (Aug. 20) in the journal Nature Geoscience.

The University of Southern California, in announcing the study, said the findings upend previous hypotheses of the seismic activity beneath the Caribbean Sea and provide an important new look at the unique tectonic interactions that are causing the Caribbean plate to tear away from South America.

The Caribbean plate is being pushed eastward due to a thick section of the South American plate called a "cratonic keel." This section of crust is three times thicker than its surroundings.

Meanwhile, part of the South American plate is being pushed beneath the Caribbean plate, a process called subduction. Intense heat and pressure gradually force water-containing magma to rise into the Earth's mantle and fuel the many active volcanoes in the region.

Unity is the great goal toward which humanity moves irresistibly. But it becomes fatal, destructive of the intelligence, the dignity, the well-being of individuals and peoples whenever it is formed without regard to liberty, either by violent means or under the authority of any theological, metaphysical, political, or even economic idea. That patriotism which tends toward unity without regard to liberty is an evil patriotism, always disastrous to the popular and real interests of the country it claims to exalt and serve. Often, without wishing to be so, it is a friend of reaction – an enemy of the revolution, i.e., the emancipation of nations and men.
