Towards a new earthquake disaster prevention system! It covers the technical limitations such as delays in emergency earthquake alerts.

We propose a "New Integrated Earthquake Early Warning System" that enables accurate alerts for all earthquakes through the linkage of a direct seismic detection device and emergency earthquake alerts. By linking with the seismic meter "Chokka-kun," which is equipped with a three-directional acceleration sensor, we can detect and report warning information for direct earthquakes and earthquakes within 30 km of the epicenter in less than one second. Real-time seismic intensity is continuously recorded (every 100 ms) during shaking, allowing for the prediction of damage based on the duration of seismic intensity above a certain level. 【Features】 ■ Covers technical limitations such as delays in emergency earthquake alert notifications ■ Accurate information reporting through real-time seismic intensity ■ Prevention of false alarms ■ Evacuation guidance during shaking and at the end of shaking ■ Information presentation usable for damage estimation *For more details, please refer to the PDF materials or feel free to contact us.

basic information

【Other Features】 ■ If an emergency earthquake alert is received in advance (generally when the epicenter is more than 30 km away), the "Emergency Earthquake Alert Receiving Device" will immediately output an emergency warning. ■ Even if the transmission of the emergency earthquake alert is not possible due to issues with the internet connection, having "Chokka-kun" allows for supplementation with its own earthquake alert information. ■ During an earthquake (while shaking is occurring), "Chokka-kun" continuously outputs real-time seismic intensity information, enabling calm situational awareness even in stressful evacuation situations. ■ After the earthquake subsides, the saved historical real-time seismic intensity data provides important information for BCP measures as an estimation of damage caused by the series of earthquakes. ■ Outputs necessary information for equipment control (emergency stop/operation) through multiple contact signals (utilizing the contacts of the emergency earthquake alert receiving device and Chokka-kun). *For more details, please refer to the PDF document or feel free to contact us.
