Chilean Earthquake…

First and foremost, our hearts and prayers go out to the victims of the Chilean earthquake, just as in Haiti. And of course for anyone in the path of any potential tsunamis throughout the Pacific region. The one thing that is a glimmer of brightness, in my opinion, in all of these natural disasters is the outpouring of good will and good gifts from the entire world. Even many sworn enemies will set aside grievances and provide comfort and aid to the victims. Remember God is good, but we humans can be pretty good to!

Here is some information I gleaned from the USGS Site concerning Chilean earthquakes:

Tectonic Summary

This earthquake occurred at the boundary between the Nazca and South American tectonic plates. The two plates are converging at a rate of 80 mm per year. The earthquake occurred as thrust-faulting on the interface between the two plates, with the Nazca plate moving down and landward below the South American plate.

Coastal Chile has a history of very large earthquakes. Since 1973, there have been 13 events of magnitude 7.0 or greater. The February 27 shock originated about 230 km north of the source region of the magnitude 9.5 earthquake of May, 1960 – the largest earthquake worldwide in the last 200 years or more. This giant earthquake spawned a tsunami that engulfed the Pacific Ocean. An estimated 1600 lives were lost to the 1960 earthquake and tsunami in Chile, and the 1960 tsunami took another 200 lives among Japan, Hawaii, and the Philippines. Approximately 870 km to the north of the February 27 earthquake is the source region of the magnitude 8.5 earthquake of November, 1922. This great quake significantly impacted central Chile, killing several hundred people and causing severe property damage. The 1922 quake generated a 9-meter local tsunami that inundated the Chile coast near the town of Coquimbo; the tsunami also crossed the Pacific, washing away boats in Hilo harbor, Hawaii. The magnitude 8.8 earthquake of February 27, 2010 ruptured the portion of the South American subduction zone separating these two massive historical earthquakes.

A large vigorous aftershock sequence can be expected from this earthquake.

As you were.

One thought on “Chilean Earthquake…

  1. See fact at the end:
    ” Chile has a history of devastating earthquakes, including the most powerful one ever measured, a 1960 quake that measured 9.5 and killed several thousand people. (By comparison, the earthquake that killed over 230,000 people in Haiti Jan. 12 measured 7.0. Each increase of one point represents 32 times more intensity.)”
