Wow! My dad lives near Acapulco. So far no major damage is being reported.Barry A. - 3-20-2012 at 12:04 PM
It's tough for me to believe that "there is no major damage" in an earthquake in the 7.something catagory.
Stay tuned.

when we had the 7.2 two years ago in Rosarito they initially said the same thing... then the devastation to Mexicali became apparent as more news
reports came in.angels4 - 3-20-2012 at 01:11 PM
I guess we will have to wait and see Woooosh. . Mother earth seems to be very active lately.bufeo - 3-20-2012 at 01:11 PM
The USGS site is reporting three aftershocks above 5.0 as well.
Felt very strong in Mexico City, and the states of Morelos, Guerrero, Michoacan, Oaxaca, Estado de Mexico, and many strong aftershocks.
They also report that Obama's daughter

Perhaps the depth, at eleven miles, is the reason for the surprisingly light damage reports.gallesram - 3-20-2012 at 02:35 PM
I spoke with 2 friends who live in Acapulco; no damage at all, according to them. It was strong but everything seems back to normal. Don't know
about towns closer to the epicenter, though.
Same reports from friends in DF.DavidE - 3-20-2012 at 04:05 PM
The quake was considerably south of Acapulco, more like in the area of Puerto Escondido. The Richter Scale can be very misleading. I much prefer the
Modified Mercalli Scale when judging intensity.David K - 3-20-2012 at 04:07 PM

Is that one use the amount of water sloshed out of a swimming pool? Bob H - 3-20-2012 at 06:12 PM

The last report I read was it was centered in Guerrero, approximately 120 miles East of Acapulco.David K - 3-21-2012 at 12:53 AM
"Modified Mercalli Scale"... when I read that yeaterday I thought it said 'Mexicali Scale' (misspelled of course)... As in the video during the
Mexicali quake of Easter 2010 of the hotel's pool sloshing water out.

The MM scale is useful. It puts earthquake effects into descriptions that folks can relate to:
MMI value Summary description used on maps Description of shaking severity Full description shortened from Elementary Seismology
[MMI I] I Not mapped Not mapped Not felt.
[MMI II] II Not mapped Not mapped Felt by people sitting or on upper floors of buildings.
[MMI III] III Not mapped Not mapped Felt by almost all indoors. Hanging objects swing. Vibration like passing of light trucks. May not be
recognized as an earthquake.
[MMI IV] IV Not mapped Not mapped Vibration felt like passing of heavy trucks. Stopped cars rock. Hanging objects swing. Windows, dishes, doors
rattle. Glasses clink. In the upper range of IV, wooden walls and frames creak.
[MMI V] V Light Pictures move Felt outdoors. Sleepers wakened. Liquids disturbed, some spilled. Small unstable objects displaced or upset. Doors
swing. Pictures move. Pendulum clocks stop.
[MMI VI] VI Moderate Objects fall Felt by all. People walk unsteadily. Many frightened. Windows crack. Dishes, glassware, knickknacks, and books
fall off shelves. Pictures off walls. Furniture moved or overturned. Weak plaster, adobe buildings, and some poorly built masonry buildings cracked.
Trees and bushes shake visibly.
VII Strong Nonstructural damage Difficult to stand or walk. Noticed by drivers of cars. Furniture broken. Damage to poorly built masonry
buildings. Weak chimneys broken at roof line. Fall of plaster, loose bricks, stones, tiles, cornices, unbraced parapets and porches. Some cracks in
better masonry buildings. Waves on ponds.
VIII Very strong Moderate damage Steering of cars affected. Extensive damage to unreinforced masonry buildings, including partial collapse. Fall
of some masonry walls. Twisting, falling of chimneys and monuments. Wood-frame houses moved on foundations if not bolted; loose partition walls thrown
out. Tree branches broken.
[MMI IX] IX Violent Heavy damage General panic. Damage to masonry buildings ranges from collapse to serious damage unless modern design.
Wood-frame structures rack, and, if not bolted, shifted off foundations. Underground pipes broken.
[MMI X] X Very violent Extreme damage Poorly built structures destroyed with their foundations. Even some well-built wooden structures and bridges
heavily damaged and needing replacement. Water thrown on banks of canals, rivers, lakes, etc.
[MMI XI] XI Not mapped because these intensities are typically limited to areas with ground failure. Rails bent greatly. Underground pipelines
completely out of service.
XII Not mapped because these intensities are typically limited to areas with ground failure. Damage nearly total. Large rock masses displaced.
Lines of sight and level distorted. Objects thrown into the air.
My bad!
