as you probably do not know, we posted two threads, between me and Malaise, there was a MAJOR earthquake in Mexico today.
Won't bore you with the details of almost non existent damage in Mexico City, but mom said it felt eternal (Per USGS it was 40 seconds). Also we have had it reported all the way from 7.0 to 7.5 depending on the news service. No USGS has not updated the map. But per multiple news services it was upgraded to 7.5, that ranges from Reuters to CNN, to El Universal and Milenio.
This is a tad of a historic detail, where my mom lives quakes are seldom felt. So if you feel there, it was major.
The point of this... is that earthquake resilience abroad does exist, though if you have kids who went to Acapulco for Spring break or family, you are in for a treat. They will have stories of evacuations and all that. Other major areas affected, and no damage.
Here is a link, mostly for the photo of the member of the Heroico Cuerpo de Bomberos, standing by one of the few damaged structures in Mexico City, and for the intensity.

So the story is that good construction codes save lives. And that we really do not have this all over again (which was after an 8.2 that lasted 90 seconds) Those two are photos from the 1985 quake.
Or this, the collapse and subsequent rescue at the General Hospital in Mexico City, where babies were rescued from the neonatal unit.
Now there was damage in far less resilient areas in rural zones, where 123 homes did collapse, much nearer to the quake and far less resilient construction. These are adobe homes in very poor, depressed, isolated areas. And there was some damage at the Chipalcingo Colonial Cathedral and some to the roads, which seems minimal. So far no reports of any deaths, or injuries.
Like Chile... it is what it is.

(34,136 posts)I think Mexico City learned from the '85 quake to improve their building standards. That may have saved some lives this time around.
Chile learned long ago that building quality makes a big difference. Unfortunately, I think Haiti is far too corrupt to be able to enforce better standards, so they will continue to have high casualty rates when they have big quakes.

(154,021 posts)But an 8.2 is hardly something to sneeze at. And they had a 7.5 two years before, I remember that one opening a hole in the wall at school. So it is thought that General Hospital was previously damaged and never fixed. Many of the survivors spoke of those gaps.
What Mexico did is enact a very robust civil defense apparatus. That thing of not checking structures does not happen any longer. A building was evacuated until it was checked by structural engineers this morning for example.
As to Haiti, if we had a 7.0 at ten kilometers depth, that is less than seven miles, under El Cajon, California, I am betting on a lot of damage. And I mean a LOT of it. Just look at La Habra, 5.1 near surface quake. That was not that strong... and the damage was minor but there.
They have no resiliency, but depth also matters, A LOT.
But Mexico has been using standards developed in Japan since at least the 1950s. The Torre Latina, built in the 1950s for example, had Japanese innovation in the sub structure. And the hotel where Obama and every head of state stays these days in Chapultepec, was built with both Mexican and Japanese engineering.

(154,021 posts)nobody answered, I assumed correctly they were fine.
They went to the sports center after that, and the kids have a story for school.

(154,021 posts)The seismograph image has the point the SMS message was sent alerting people of the incoming quake.
It gave people a 64 second head warning.
And in the meantime USGS is still thinking about this...
