Earthquake Alarm

The device uses a P-wave sensor to detect the initial, faster-moving compression waves that precede the more destructive shear waves (S-waves) of an earthquake. By identifying these primary waves, it can trigger an alert a few seconds before the main shaking begins.

While five seconds is a short window, it is often enough time to drop, cover, and hold on, or to move away from hazards like heavy furniture or glass. This brief alert is designed to minimize panic and give you a critical head start on taking protective action.

The device is engineered for maintenance-free operation for up to two years on a single 9V battery. We recommend testing the alarm periodically to ensure it is functioning correctly, but you will not need to worry about frequent battery changes.

Yes, the unit features a sharp, high-decibel audible siren specifically engineered to cut through ambient noise. It is designed to be loud enough to alert you even if you are sleeping.
