7.2 Mexicali quake shifted Earth's crust 31 inches, NASA images show


The 7.2 Mexicali, Mexico, earthquake was so powerful that it shifted the Earth's crust 31 inches near Calexico, Calif., according to radar images and data released by NASA on Wednesday.

Eric Fielding, a geophysicist with the Jet Propulsion Laboratory, said the quake shifted the crust on the Mexican side of the border even more -- as much as 10 feet, according to research by European and Japanese scientists.

Fielding said that while the numbers sound dramatic, they probably were not noticed by humans immediately after the quake because they occurred in a remote desert area.

The Easter Sunday quake killed two people and collapsed numerous buildings in the Mexicali area. There was more than $90 million in damage in California alone -- mostly in Imperial County.

The images were taken by the Uninhabited Aerial Vehicle Synthetic Aperture Radar, which is operated by NASA's Jet Propulsion Laboratory.

I've seen similar images at Winterland in San Francisco.

I live in Mexicali. I was raised in the Salinas Valley and am used to earthquakes, but this 7.2 one in Mexicali was a very strong quake. Fortunately, I had lots of tap water accumulated in recycled plastic jugs, canned goods, batteries for light, matches, and firewood. One thing we have to do is: Be Prepared, have enough drinking water for each person in the household, possibly a packback with personal items for each person also, and if needed over the counter remedies that you use on a regular basis and other staples that you really need, but your backpack is the only item you'll carry with you in case you have to leave your house, so go through all your documents beforehand and have handy if there is a next time. Keep calm above all.

2012 her we come........lol....

wow mexico is getting closer every day watch out arizona lol

Oh my, that's just so scary. I remember when I was young, we would find all these little things to play with in the yard while the aurora danced above us. And I found myself thinking.."Good lord, I could be one of those stars.." You sit and you reflect, and as your eyes meet oxygen, you realize, actually, all we've ever been, are, and will be, is dust to dust..

Come Earthquake, and I will fight over you.. Above and below.

The 2010 Easter Sunday shaker was an underground collapse. It was not a basic fault movement. While there has been some surface earth shifting, this earthquake was not at all like an earthquake on the San Andreas Fault. Underground collapses are shallow and the aftershocks are at random; they do not follow a fault line. Most are caused by the removal of water, oil or minerals from beneath the surface of the earth. Shallow collapses can do a lot of damage. Two other examples of underground collapses were the Landers shaker of June 28, 1992, and the Northridge shaker of January 17, 1994. The Northridge shaker did a lot of damage. The mine collapses in Utah shook the earth and the shakers around Oklahoma City are shallow collapses where oil has been removed.
When magma from the core of the earth comes up into a real earthquake fault, an energy is given off that some animals and a few humans, like myself, detect.
At this time I can detect underground energy flows that could tigger seismic action are: 1. 30 miles west of Red Bluff, CA; 2. Near the CA-OR border, near the Pacific Coast; 3. Near Mt. St. Helens; 4. Yellowstone National Park; 5. About 50 miles east of Redding, CA, near Lassen Peak.
I am able to face those directions and feel the energy in my body.

very intersting I have a idea the penensula that seperate so. calif and mexico where the water ends. I strongly believe the orean water is creeping up towards northern calil ? Anyway I not a scientist at all, just thinking it's going to take thousands and thousands of years for the oceans water reach so. Calif. Scary stuff maybe ?

Must have been mans fault the earths crust shifted all that drilling and mining just sent it off its rocker. We need a law an investigation. Lets fine all the people that drill and mine the earth.





omgosh aaaahhhhh

Maybe that's why my well doesn't work anymore. It was fine for years and after the quake the well doesn't work.

DAMN but really who cares

No NEWS about this, the earth moves when it quakes!
Seems every time a quake happens, some wacko comes out to tell you "the earth moved"!

Oh and the Chili quake shifted the earth axis, did ya hear that one?
So small it can't be measured they say, so how do they know?
