So terrifying, We can’t imagine what all of these people are going through.And still people drive & then run over!!Mexico was rocked by the quake, which measured 7.1 on the Richter scale on Tuesday, in the middle of the day.This might be the result of a geological phenomenon known as soil liquefaction.
Which describes a phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid.
The phenomenon is most often observed in saturated, loose low density or uncompacted, sandy soils. The effects of soil liquefaction on the built environment can be extremely damaging.The death toll from Mexico’s most lethal earthquake in a generation has now exceeded 230.The impact was intense—one building erupted in flames shortly after the earthquake.
