If you’re living in a high risk earthquake area, like me here in sunny California, then you might appreciate the early warning the earthquake alarm box could provide. The QuakeAlert is battery powered and provides up to a 2 minute early warning of an impending quake. The box works by reacting to βto vertical ground movements caused by vibrations in the form of motion waves from an earthquake.β? The unit is designed to be wall mounted on a cushion of “651 Closed Cell Neoprene pressure sensitive adhesive foam.” The alarm itself is encased in a pewter colored aluminum and steel case.
The device retails for $200 US and is available here.
