An Earthquake Primer: P-Waves and S-Waves

The P-wave is an earthquake’s fastest-moving wave that travels in advance of all other waves. The P-wave is detected every time by Pro-teq sensors operating 24x7 for your safety. The S-wave follows the p-wave and carries the destructive force of the earthquake. The separation between the P-wave and the S-wave is where Pro‑teq adds tremendous value by issuing a warning and initiating emergency protective actions before the violent shaking of the S-wave arrives.

According to the National Earthquake Information Center our planet experiences about 20,000 earthquakes each year or 55 earthquakes per day. It is critical then, to determine which quakes are dangerous and which are not. Dangerous quakes carry powerful destructive forces that can destroy lives, property, and disrupt global economies. Alerting and initiating emergency protective actions BEFORE the violent shaking starts are desirable personal, business, and public policy goals.

Pro-teq’s ONSITE is an autonomous device which contains earthquake sensors and a controller. The ONSITE is engineered to be network capable and does not need a data center like other systems. In a network configuration, the ONSITE provides instant earthquake information to the Earthquake Warning Receivers (EWR). An EWR performs the same control functions as an ONSITE but without earthquake sensors. This makes EWRs more affordable when a Pro-teq network is present. In the event of an earthquake, the system instantly resets for aftershocks. Issuing an alert and initiating emergency protective actions before the earthquake strikes is exactly what Pro-teq does and we do it better than anyone else.
