Earthquake early warning system. An animation detailing how earthquake warning systems work: When P waves are detected, the readings are analyzed immediately, and, if needed, the warning information is distributed to advanced users and cell phones, radio, television, sirens, and PA systems / fire alarm systems before the arrival of S waves.
The PHIVOLCS earthquake intensity scale ( PEIS; Filipino: Panukat ng Pagyanig ng Lindol) [1] is a seismic scale used and developed by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) to measure the intensity of earthquakes . It was developed as upon a specific response to the 1990 Luzon earthquake.
