The speeds of today’s data telecommunications systems are many times faster than seismic waves.

P-waves travel almost twice as fast as the damaging S-waves and surface waves and.

Technical Partners span multiple industries and sectors, and include private for-profit companies, public entities, and nonprofits that can benefit from becoming part of the ShakeAlert System.

Technical Partners are integral to the ShakeAlert System because they are responsible for producing and delivering ShakeAlert-powered alerts to people and critical systems.

The ShakeAlert sensor network detects earthquakes quickly, and immediately transmits data to a ShakeAlert Processing Center, where estimates of the location, size, and shaking intensity of the earthquake are determined in a matter of seconds. P-waves are followed by slower moving, and generally more damaging waves (secondary or S-waves) and surface waves that travel about 2.5 miles per second. The fastest-moving seismic waves (primary or P-waves) travel about 3.7 miles per second and generally do not produce strong shaking. ShakeAlert 3 Basic Steps: Sensor Networks to processing center to users.ĭuring an earthquake, a rupturing fault produces several different kinds of waves that carry energy awayįrom the epicenter like ripples from a rock thrown into a pond.

Data from individual sensors across large regions are combined to maximize accuracy and alerting time during moderate-to-large earthquakes. This network uses sensors distributed over a wide area where earthquakes are likely to occur on the West Coast of the United States (with nearly 1,700 anticipated on network build-out). The ShakeAlert system takes a network approach to earthquake detection and alerting. These automated actions could include slowing a train, closing valves, issuing a public announcement, and many others.

Then, technical partners, which have entered into a license agreement with the USGS, use this information produce and deliver an alert that prompts people to take a protective action, such as DROP, COVER, AND HOLD ON, and/or to trigger an automated action that can protect vital systems, equipment, facilities, and infrastructure. If an earthquake becomes large enough to meet USGS alert thresholds, a ShakeAlert Message is issued.

Rather, the USGS-operated ShakeAlert Earthquake Early Warning system detects an earthquake that has already started and estimates its location, magnitude and shaking intensity. DETECT, DELIVER, PROTECT: ShakeAlert ® is not earthquake prediction.
