The earthquake alarm is only approved by the American International Rescue Team (ARTI) Knowing that you and your family are safe, you will feel comfortable!
The purpose of earthquake alarms is to provide a timely warning of seismic activity by detecting P-waves (compressional waves) of earthquakes, which travel faster than the more destructive S-waves (shear waves). Earthquake alarms save valuable seconds by eliminating speculation about seismic activity. Earthquake alarms can detect large earthquakes that occur hundreds of miles away, as well as moderately mild earthquakes that occur many miles around you. A very important advantage of an earthquake alarm is that it can remind you and wake you up at the moment of an earthquake, allowing you to hide or be with your family. The human brain relies on the combination of the inner ear and visual field to determine body movement at the moment of an earthquake. Disorientation and well-known dizziness can cause confusion and instinctive freezing for many seconds during earthquakes. Sound itself also plays a role in earthquake detection and can cause misunderstandings. The slamming of the garage door and the low rumbling of big trucks lead people into the false assumption that they are experiencing an earthquake. Earthquake alarms can eliminate confusion, save valuable seconds, and make people feel at ease.
