The San Andreas Fault is one of the most dangerous tectonic systems in the world, separating the North American and Pacific plates. Along the historyhas been responsible for numerous earthquakes on the West Coast of the United States, and scientists are warning of the possibility of a large earthquake known as the “Big One,” which could have devastating effects on California and nearby regions.
The San Andreas Fault: A Latent Threat in California and Its Impact on Mexico
According to NASA, the Earth’s crust is made up of several slowly moving tectonic plates. Off the coast of California, two of these plates—the Pacific Plate and the North American Plate—shift sideways, creating constant friction that, if released, could trigger a large earthquake. This fault, which runs through areas such as San Francisco, San Jose, and Los Angeles, has the potential to destroy up to 17,000 concrete buildings in high-risk areas, as well as disrupt essential services such as water and telecommunications.
The possible impact on Mexico
Although the greatest damage would be concentrated in California, the effects of a major earthquake on the San Andreas Fault could be felt in Baja California, Mexico, due to its geographic proximity. Experts predict that an event of such magnitude would affect a radius of approximately 160 kilometers from the epicentral region.
When will the “Big One” happen?
Historical and geological studies suggest that large earthquakes in the San Andreas Fault region occur approximately every 150 years. However, this is not an exact prediction, and it is not possible to determine with certainty when the next large earthquake will occur. The last time the fault was activated was in 1906, when an earthquake devastated San Francisco, causing thousands of deaths and enormous property losses.
Historic earthquakes on the San Andreas Fault
- 1857: An earthquake in Southern California.
- 1906: The famous San Francisco earthquake, one of the most destructive in the history of the United States.
Constant monitoring of the San Andreas Fault is crucial to mitigate the effects of a potential major earthquake, both in the United States and in nearby regions such as Baja California.
