PLANETARY TREMORS: Powerful Magnitude 6.8 Earthquake Strikes Off Chile – No Tsunami Seen From Initial Reports!

May 20, 2013 – CHILE - A magnitude 6.8 earthquake struck off the coast of Chile on Monday, the U.S. Geological Survey said, but Chilean emergency authorities said they saw no prospect that the tremor would generate a tsunami.

The quake struck 400 miles (640 km) west of Puerto Aisen at a depth of 6.2 miles, the USGS said.

It said the quake had occurred at 5:49 a.m. Chile time (10.43 a.m British time)

Chile’s emergency office said on Twitter that the quake did not have the conditions necessary to generate a tsunami. It added the quake was not felt in the country.

The USGS pinpointed the quake in the Nazca tectonic plate area. - Reuters.

The South American arc extends over 7,000 km, from the Chilean margin triple junction offshore of southern Chile to its intersection with the Panama fracture zone, offshore of the southern coast of Panama in Central America. It marks the plate boundary between the subducting Nazca plate and the South America plate, where the oceanic crust and lithosphere of the Nazca plate begin their descent into the mantle beneath South America. The convergence associated with this subduction process is responsible for the uplift of the Andes Mountains, and for the active volcanic chain present along much of this deformation front. Relative to a fixed South America plate, the Nazca plate moves slightly north of eastwards at a rate varying from approximately 80 mm/yr in the south to approximately 65 mm/yr in the north. Although the rate of subduction varies little along the entire arc, there are complex changes in the geologic processes along the subduction zone that dramatically influence volcanic activity, crustal deformation, earthquake generation and occurrence all along the western edge of South America.
