Earthquake Early Warning System

Earthquake Early
Warning System

Every second counts. The Earthquake Early Warning System (EEWS) developed by Sanlien can detect earthquakes before they arrive. The advance warning allows people to take action to escape from disasters.

On-site Earthquake Early Warning P-wave Algorithm

Onsite Early Warning

P-wave Early Warning: Provides early warnings based on P-waves.
Device at User’s Locality: The device is located at the user’s locality.
Effective Regardless of Epicenter, Magnitude, and Depth of Earthquake: Remains effective regardless of the earthquake’s epicenter, magnitude, or depth.
P-wave 3-Second Displacement: Detects P-wave displacements within 3 seconds.
pALERT S303 Calculation: Utilizes the pALERT calculation method.
Local Intensity: Provides information on local intensity when S-waves arrive.

Regional Early Warning

Earthquake Occurs at a Remote Location: Used for earthquakes occurring in remote areas.
Seismographs Installed Around the Epicenter: Utilizes seismographs placed around the earthquake’s epicenter.
Primary Wave Travels Faster than the Seismic Wave: The primary wave travels faster than the seismic wave.
Epicenter, Magnitude, Depth: Provides information on the earthquake’s epicenter, magnitude, and depth.
Central Computer Calculation: Calculations are performed by a central computer.
Attenuation Formula for Location/Site Effects: Incorporates an attenuation formula to account for location and site effects.
Intensity Estimation and Countdown Seconds: Offers intensity estimation and countdown seconds.

Advantages of Sanlien Technology's Earthquake Early Warning System

Due to the calculations of the Central Weather Bureau’s Regional Warnings (as an example in the case of Taiwan) taking approximately 13-18 seconds, they are unable to provide an early warning effect to areas located within 50-70 km from the epicenter. This is where local monitoring and warning devices play a crucial role. Sanlien Technology offers both regional and local early warning services, reducing the blind zone from 70 km to 12 km, and this can also be automated through integration with electronic facilities.
