7.8-magnitude Quake Hits Ecuador's Central Coast

[Andie]

I don't get to post powerful quakes very often and now the Ring of Fire has supplied two.

Another shallow quake at 16 miles deep.

all of the subduction zones for he pacific have been active over the past decade, with the exception of the Cascadia line. My crackpot and uneducated theory has me believing that the relieved pressure from the the other zones is giving the tiny Jun de Fuca plate some breathing room.

 

Or the opposite.

I'm not sure how active the spreading center is off the coast of the Pacific Northwest, but I would guess that a significant earthquake will happen there again - may not be as big as these other ones have been though.

 

Geologic theory is that the Juan de Fuca plate was part of the Cocos Plate (see link), which was called the Farallon plate. It's subduction under North America help raise the Rocky Mountains, the Colorado Plateau, the Wasatch Mountains, and set off the volcanic activity in northern Arizona.

The earth quakes are increasing every year across the globe. Many countries are suffering from the after affects of earth quake. Yesterday,  earth quake was recorded in Cyprus Region with 3.0 magnitude. Today, another earthquake is recorded in Oklahoma, United States and the magnitude of the earth quake is 2.6.

Oklahoma has been shaking like a bowl of jello. Many theorize that it's fracking water injection add pressure to small faults or lubricating them to slip. Either way, it's unnerving the populace.

In Japan, there's a debate raging about earthquake prediction. The scientists are divided over earthquake predictions. The Japanese government is focusing on the Nankai Trough research, a fault line which runs along the main island of Honshu. The scientists are worried if the fault line has not ruptured for a then may be an earthquake is due.
