Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Chile Quake Moved Cities by 3m

Concepcion: The Roving City Moved by 305cm

The M8.8 megaquake that struck the coast of Chile on February 27, moved the city of Concepcion at least 3 meters (10 feet) to the west, shifting other parts of South America, and places as far apart as the Falkland Islands and Fortaleza, Brazil, researchers say.

Initial measurements, produced from data collected by researchers from four universities and earthquake monitoring centers, as well as geophysicists on the ground in Chile, who depicted the power behind the Chilean megaquake, listed as the fifth-most-powerful instrumentally-recorded earthquake ever.

Buenos Aires, the capital of Argentina  moved west by about 2.5cm (1 inch). And Santiago, the Chilean capital, moved about 28cm (11 inches) to the west-southwest. The cities of Mendoza and Valparaiso, located northeast of Concepcion, also moved by more than 13cm, and 27cm respectively.

The megaquake occurred in a region of the Pacific Ocean which is known as the “Pacific Ring of Fire,” an area of major seismic activity. Major seismic stresses are caused because tectonic plates move press against each other at various fault zones, resulting in earthquakes which release built-up geologic stresses along these convergence zones.

The Chilean megaquake occurred where the Nazca tectonic plate subducted [plunged beneath] the neighboring South American plate.
