Earthquake Early Warning System

Collision avoidance

ShakeAlarm® is a cost-effective, highly reliable Earthquake Early Warning System (EEWS) which provides critical minutes or seconds of warning in order to minimize loss of life and assets. This is done by recognizing and quantifying the faster, but lower energy, P (compressive) wave which is the precursor of the more damaging S (shear) wave.

When used in conjunction with industrial or civil infrastructure control systems, these critical seconds of warning can be leveraged to save lives, minimize runaway failure modes in critical structures, and shut down gas and electricity feeds to infrastructure minimizing fire risk to assets after the seismic event.
