Earthquake early warning methods have lengthy been applied in quake-prone international locations like Mexico and Japan, with California changing into the primary state in america to supply a statewide early warning system when the Earthquake Warning California System launched in 2019.
The system operates by taking knowledge from greater than 900 sensors positioned throughout the state that may detect earthquakes.
When an earthquake triggers the sensors, that knowledge is shipped to processing facilities to find the earthquake, decide the magnitude, and the estimated shaking. The MyShake App then sends a warning to smartphone customers which have put in the app and are within the neighborhood of the earthquake.

Residents will solely obtain notifications for quakes with a magnitude 4.5 or larger, Gudel mentioned.
How a lot time is there between the warning and shaking?
