This week's quakes - Blue Today

(Best Syndication News) While the new President was getting ready to be sworn into office, another large earthquake struck the country of Chile this morning. This earthquake was closer to the surface than the quake that hit last month.

According to data collected by the USGS, this quake was located at a depth of 6.8 miles compared to the February 27th tumbler which was at a depth of 21.7 miles. That earthquake, centered offshore with a magnitude of 8.8, was the seventh largest quake in recorded history. Today’s quake was centered in the Libertador O Higgins region of Chile.

Dignitaries were filing into the swearing-in ceremony of Sebastian Pinera as Chile’s President. The formal procedure was hastened and performed quickly and the audience quickly headed for the exits. The whole ceremony only lasted about 30 minutes.

It is not certain whether today’s quake was a pre-shock, an aftershock of the February 27th earthquake or a separate earthquake. The earthquake occurred in the “aftershock region”. “The March 11 earthquakes almost certainly occurred as the result of the change of regional stress caused by the February 27 earthquake,” the USGS said in a statement.

“Preliminary analyses of their locations and seismic-wave radiation patterns, however, imply that the March 11 shocks occurred as the result of normal faulting within the subducting Nazca plate or the overriding South America plate, unlike the February 27 earthquake, which occurred as thrust faulting on the interface between the two plates.”

The USGS is still investigating today’s earthquake. There have been several aftershocks this afternoon including some measuring over 6.0 (6.0 and 6.7). Concerns about a possible tsunami were quickly alleviated.
