Ryan Zukowski Geological Perspective 4/11/06 Extra Credit Peru Earthquake The Earth's solid surface is divided into over a dozen different plates that float on the mantle. As these plates move and shift relative to one another they release enormous amounts of energy in the form of earthquakes. There are many earthquakes around the world, and are not evenly distributed. However, the boundaries between the plates grind against each other, producing most earthquakes. This ultimately helps us to define the plates of the world. A majority of the world’s earthquakes occur around South America because there is a oceanic plate that converges with a continental plate, causing stress at a subduction zone. Also, there are a lot in Europe, the West coast of the United States and

Unformatted text preview: Alaska. Most earthquakes however appear to occur between the Pacific and Indian plates, all the way from Australia up to Asia. On April 8 th 2006, an earthquake with a magnitude of 4.8 occurred near the Coast of Peru. The Earthquake took place at 3:06:15. Because South America is such an active place for volcanism, Peru has experienced many earthquakes. The Earthquake was caused by thrust faulting along the boundary where the Nazca plate subducts beneath the South American Plate. As the Oceanic plate essentially dives under the Continental plate, subduction occurs and since it was along a fault, an earthquake was caused. Also, there are many volcanoes that can form from these plate boundaries....
