Mexico Earthquake at 8.x

Damn now Mexico has been hit by a third large earthquake.

A massive earthquake hit Mexico Friday evening, leaving buildings shaking throughout the southern portion of the country.

The earthquake was first measured as a 7.5-magnitude and later lowered to having a 7.2-magnitude by the U.S. Geological Survey. The epicenter was found along the Pacific coast near Santiago Ixtayutla, a town in the state of Oaxaca in the southwestern area of the country.

There is no tsunami threat from the quake, according to the Pacific Tsunami Warning Center.

Videos on social media show people in the streets grabbing onto a car as the ground started shaking. Footage inside a building show lights swaying back and forth with people lined up along a hallway.

It's unclear if any damage or injuries were reported.

Too bad they don't have any building codes down there. Then it wouldn't be so bad. Maybe they should adopt California's standards.

They do have building codes, and structures that comply have gone through the biggest quakes (like the 1985 one) with absolutely no damage.

An example is the 44 story Torre Latinoamericana, built in 1956. It was empty with no tenants until the 1957 earthquake left it with zero damage. In the 1985 8.1 earthquake, while most buildings in the area were severely damaged, the Torre did not even have a tiny crack. It has been used as an example of how to build in highly active seismic land.

The problem in any developing nation is that superior construction is expensive, and many people, particularly in rural areas, don't comply with code because they need housing and can't afford a contractor or blueprints or permits.

Makes me wonder how houses and buildings in the rural Arkansas, Tennessee and Missouri area (near where the series of 8+ quakes centered at New Madrid in 1812) would fare if comparable quakes were to occur now. Or the Seattle / Tacoma area if there is the predicted 9+ tremor.
 
It's a blessing there weren't more injuries from this latest quake. Something to be thankful for, certainly.
 
The Mexicans, with whom I've spoken, say they have nothing like what we have with all the permits, inspections, fees. There is a permit for foundation, framing, electrical, plumbing, HVAC, roofing, and finish. (In America, there is a permit for EVERYTHING.)
Not too many pre-1900 structures around here. Its not because of storms, or earthquakes. Its because modern termiticide did not come into use till 1940 or so. Many of those old structures became lunch for termites, powder post beetles, etc.
And by 1900 they knew about earthquakes and had built accordingly.
