Global earthquake ALERT: California told to prepare for 'BIG ONE' after Mexico tremors

THE SERIES of large earthquakes that brought death and destruction to Mexico last month may have triggered a chain reaction of tremors on the global scale. Mexico was rattled last month when the biggest earthquake in more than a century, measuring 8.1 on the Richer Scale, struck off its southern coast, killing 90.

Then, just over a week later, Mexico City was virtually flattened by a magnitude 7.2 earthquake that reduced entire communities to rubble and killed 300. In the following days a swarm of tremors greater than magnitude 5.0 continued to blight the nation. These tremors were thought to be “aftershocks”, when stress is transferred from one fault line to another close by. Natural disaster specialist Dr Simon Day told Daily Star Online similar aftershocks may have caused the record magnitude 8.1 quake through a process known as “stress triggering”. earthquake warning GETTY TREMOR THREAT: The earthquakes in Mexico may have global consequences, experts believe Mexico City devastated by 7.1 magnitude earthquake – dozens dead Devastation has hit Mexico City as a massive earthquake collapsed buildings and killed dozens 1 / 15 People remove debris of a building which AFP/Getty Images People remove debris of a building which People remove debris of a building which Picture of debris of the facade of a bui 7.1 earthquake shakes Mexico's capital Picture of debris of the facade of a bui He said: “For several months leading to the big 8.1 earthquake, there was a sequence of smaller earthquakes on a zone further south. “This may have stressed the deep fault zone that produced the 8.1 earthquake. “That then stressed the fault zone in the part of the slab further north that produced the 7.1 earthquake a week later."

He said: “For several months leading to the big 8.1 earthquake, there was a sequence of smaller earthquakes on a zone further south.
“This may have stressed the deep fault zone that produced the 8.1 earthquake.
“That then stressed the fault zone in the part of the slab further north that produced the 7.1 earthquake a week later."
Dr Day, of University College London, said research shows this process could continue in the coming weeks and months, causing small and large earthquakes on neighbouring fault lines.
