Why is Mexico so prone to earthquakes?

Mexico is prone to major earthquakes because it is one of the earth’s subduction zones. The Cocos plate is forcing its way beneath the North American plate, which increases the risk of major earthquakes.

Mexico has a long history of destructive earthquakes. It is one of the world’s most seismically active regions.

The mayor of Mexico City reported that buildings in at least 44 locations had collapsed or been severely damaged , including supermarkets and blocks of flats. As a result of gas pipes rupturing, fires were also reported across the city.

Coverack flash flood

On 18th July 2017, a major flood event hit Coverack on the Lizard peninsula in Cornwall.

Heavy rainfall started falling at around 3pm on the Tuesday afternoon. The storm failed to move eastwards as expected and dumped an unusually large amount of water on the village and surrounding area. In 2.5 hours, 105 mm of rain fell, compared to the usual July average of 62mm. This flowed down towards the village, sweeping rocks and large boulders with it.

Water swept down the main road into the village, inundating houses and businesses, before plummeting into the harbour below. A ‘major incident’ was declared as Coastguard helicopters were dispatched to the scene to airlift residents to safety.
