For those of you following the earthquake in Chile, there are two articles you may be interested in. Both come from Science Daily and are focused on different aspects of the zone. One is very technical about the plates in the area and the other is about future quakes.
Here in the Pacific Northwest we have a demon in waiting. A 9.0 off are coast that will alter the life of every man, woman and child in Oregon, Washington and Northern California. But for us, that is last big one we expect. The clock resets itself for another 100 years or more.
Sadly, this is not the case for the good people in Chile. In 2010 they lived through an 8.8 and this April 8.0. Below is a sample of the Science Daily article:
This one is aimed more for those of us that study or find a interest in earthquakes. Think of it as the diagram for the plates of South America.
“An M6.7 earthquake with similar faulting mechanism occurred on March 16, 2014 and was followed by 60+ earthquake of M4+, and 26 earthquakes of M5+. The March 16 earthquake was also followed by three M6.2 events on March 17, March 22, and March 23. The spatial distribution of seismicity following the March 16 event migrated spatially to the north through time, starting near 20oS and moving to ~19.5oS. “
