As of May, 2021, the US earthquake early warning system can issue earthquake alerts to cellphone users in California, Oregon, and Washington. The MyShake app is an early warning system that aims to let people know about incoming shaking, so they can have at least a few seconds to find a safe spot to ride out the earthquake. The alert system is successful because communications systems are now faster than the speed of shaking waves moving through the ground.

The earthquake early warning system could also give residents in the Pacific Northwest as much as 80 seconds of warning ahead of shaking from a magnitude nine earthquake along the Cascadia Subduction Zone. This is a monstrous fault zone off the West Coast. This fault last ruptured in such a quake on Jan. 26, 1700, and sent catastrophic tsunamis not only to the Pacific Northwest, but thousands of miles away to Japan.

The earthquake early warning system got a bit of a test run in Los Angeles County last September when a magnitude 4.5 earthquake hit the South El Monte area. This triggered an alert which was sent to 2.2 million mobile devices.

Possible Preaching Angle:

The Bible is an early warning system for the devastating judgment about to jolt the entire world. Those who listen can take shelter before it strikes (Mark 13:8; Luke 21:11).
