The Devastating Impact of Earthquakes: What Will Happen When the Big One Hits the West Coast?

TLDRDespite the uncertainty, a major earthquake on the West Coast would cause widespread devastation, including collapsing buildings, fires, landslides, and major damage to infrastructure. The estimated cost of such an event is $200 billion, with thousands of casualties. Californians should have a preparedness plan in place, including water and food supplies, and be ready to stay in their current locations.

Key insights

:warning:The San Andreas Fault is the major danger in California, with a predicted 7.8 magnitude quake being the most likely scenario.

:house:Older buildings and structures are particularly vulnerable to damage and collapse during an earthquake.

:fire:Fires are historically the biggest hazard following earthquakes, causing significant damage and loss of life.

:oil:Ruptured gas and oil pipelines could lead to explosions and further destruction.

:dollar:The economic impact of a major earthquake includes lost infrastructure, population loss, and the cost of damages.
