Posted on 04/18/2014 7:55:25 AM PDT by illiac
MEXICO CITY (AP) A seemingly strong earthquake is shaking Mexico's capital.
There is no immediate word of damage or casualties and seismologists have not yet issued a calculation of its power or epicenter.
Mexico City is vulnerable even to distant earthquakes because much of it sits atop the muddy sediments of drained lake beds that quiver as quake waves hit.

USGS says 7.5. That’s gonna be bad.
That’s cuz the 1st wookie is still burping.
It’s actually centered on the coast, closer to Acapulco than to Mexico City.
DF is built almost entirely on fill.
30 miles deep. Probably not a serious problem but large quakes have been moving north in the last year.
The cardboard and tar paper covered shacks will probably hold up better than the buildings.
It is bad. Anything above a 6 has to be.
Prayers for all those in the wake.
If that earthquake was 10 to 20 km (6.2 to 12.4 miles) beneath the ground, the damage could be enormous. But being 30 miles down, the damage may be not so significant.
37km (23mi) N of Tecpan de Galeana, Mexico
53km (33mi) NW of Atoyac de Alvarez, Mexico
56km (35mi) E of Petatlan, Mexico
81km (50mi) S of Ciudad Altamirano, Mexico
265km (165mi) SW of Mexico City, Mexico

Whole lotta shakin’ goin’ on.
Sure seems that way lately....
You would think that after the 86 quake, they would have beefed up their buildig codes.
We had an earthquake while in Mexico. Husband like so lied...told me it was construction at the base of the mountain.
Actually I feel a bit bad for that quip if this thing is a 7.5, this is no joking matter.
I know. Just laughing ahead of the mother earth crowd who will actually blame it on fracking.
There will have to be a man caused reason assigned.
Actually I think that rumors are swirling that started in the WH that this latest Earthquake is Bush´s fault.
USA Today is reporting 7.5
That is bad.
been observing those big ones creeping up the coast on that ring of fire.
actually watched this one live on the ABC cam. They show up on that local Los Angeles cam with what I call a “ Etch a Sketch” pattern. I went to the USGS site and sure nuf... there it was a 7.5 in Mexico.
About the same time of the year that the big one hit in North Mexico on Easter Sunday several years back.
A scary thing that happened in New Zealand is that if the soil has a high water content it can liquify in a strong quake.
What’s with these liberals, trying to tie everything to global warming?
Even an event such as a quake, which has nothing to do with the weather, is somehow blamed on global warming???
There is a geologic theory that says very large quakes cause slow cascade ruptures.
“Earthquake Alert” app has me monitoring movement 24/7.
CA/OR/WA is the only area on the Ring of Fire which has been fairly quiet since 2004 Indonesia.
The 'Ring of Fire' seems to be a wee bit restless lately. Y'all look out now, y'hear.
It is bad, especially in that location and at this time. Lots of people down there celebrating Easter weekend. Loss of life and property is pretty much a given at that scale.
Probably, but I’m sure they grandfathered in the multi-family buildings of “tar-paper” and “corrugated aluminum”.
wow neat map and site. Thanks.
Bookmarked that one.
I know...sigh. Live in North East Los Angeles and do my share of monitoring too.
I talked to someone in Mexico this morning (a hundred miles away). Said everyone was outside doing the stations of the cross, but they could feel the quake was very strong.
I know as well. I keep saying...Cascadia Subduction Zone. It let go 400 years ago. It’s due. And when it did let go, it was BAD.
I lost at least one tomato plant and my green beans are damaged because of low tempatures. Damn global warming!
Yes - liquefaction can happen almost anywhere strong quakes and moist soils combine. Sedimentary soils are bad, as are sandy-type soils. Just one example:
Note that many Philippine cities are in such areas.
Anyone who’s walked along a sandy or muddy creek or river bed for very far has probably found areas that even without shaking, seem solid enough until you try to traverse them.
Much of the mid-Mississippi valley in the U.S. is at high risk as well.
Mexico City is above an ancient volcano.
Much of Port Royal, Jamaica was destroyed in 1692 when liquefaction caused by an earthquake made entire neighborhoods submerge and disappear.
It basically becomes quicksand.
Or ? how about that old film of a earthquake in a harbor ? and you can see the bottom of the harbor fall out....
