Mexico earthquake: The neighbourhood where one house survived. While more than 100 buildings collapsed around it, the home of Hortensia Navarro in Mexico's Morelos state managed to withstand the impact of the devastating 7.1 magnitude earthquake.

Mexico earthquake: The neighbourhood where one house survived

Her house, in Jojutla, is still standing. The surrounding school, church and dozens of other homes, meanwhile, have been reduced to rubble. Jojutla is one of the towns closest to the epicentre of Mexico's latest quake, which struck on Tuesday afternoon killing more than 230 people across the country. "I don't get it, I don't get it," Ms Navarro said while looking around.

She added, without finishing her sentence: "This little house is very sturdy, you see, because look at all the neighbours…" Wherever you look in the area of Emiliano Zapata in Jojutla, there is only devastation. Almost all of the buildings in the area were constructed using solid materials - concrete, metal rods and bricks - but they were not able to withstand the intensity of the earthquake that originated less than 50km (30 miles) away.

Entire towns in Mexico flattened as scale of earthquake damage emerges.

The death toll from Tuesday’s 7.1 magnitude quake rose to 282, including at least 137 in the capital, and was almost certainly set to rise as rescue workers continue to search the precarious ruins amid the threat of aftershocks, collapsing rubble and gas leaks. Rupture within tectonic plate is probable cause of Mexico earthquakes. We are often reminded about the force and devastation from earthquakes that occur around the Pacific Ring of Fire.

Rupture within tectonic plate is probable cause of Mexico earthquakes

The titanic collision of two tectonic plates, which firmly lock together and accrue strain over tens to hundreds of years, eventually releases this pent-up energy as a large earthquake. We have seen such quakes striking Indonesia, Chile and Japan over the past 15 years. #mexicoearthquake #MexicoQuake #geographyteacher All ≥M5 quakes since 1900. All ≥M7 AND ≤30km deep since 1900.

Mexico earthquake: soft soil makes capital shake like it was 'built on jelly' The soft soil that lines the ancient lake bed that Mexico City is built on amplified the shaking from Tuesday's earthquake and increased its destructive force, seismologists say, as they try to better understand the quake that has killed more than 200 people.

Mexico earthquake: soft soil makes capital shake like it was 'built on jelly'

Scientists are looking at other quirks of the magnitude 7.1 earthquake, including the absence of aftershocks and if it is somehow related to a distant, even stronger, Mexican temblor that struck a dozen days earlier. 'Like being built on jelly' Mexico City is built on deep, soft soil that was once the bottom of a lake. Instead of cushioning the city from earthquakes, it exaggerates their effects, said James Jackson, a professor of geophysics at the University of Cambridge in England.

" A couple of blocks away, he saw crowds of people staring across the rubble of another building, an eight or 10-storey apartment complex.
