The Importance of Early Earthquake Warnings in Disaster Management Strategies

On June 26, 2023, a significant earthquake with a maximum intensity of 6 on the Japanese seismic scale struck the area around the Fuji Five Lakes in Yamanashi prefecture at approximately 10:29 PM. Particularly, the town of Fujikawaguchiko recorded the highest intensity. The tremors were felt across a vast area from the Tohoku region to the Chugoku region, resulting in varying levels of intensity ranging from 5 plus to 1. Our heartfelt sympathies go out to those affected by this natural disaster.

The emergency earthquake notification service "ProP biz" offered by Nankai Electric Co., Ltd. (headquartered in Osaka, with CEO Ryohei Omae) plays a crucial role in facilitating disaster response. The service delivers predictive information about seismic activity before the tremors reach a specific location, effectively aiding businesses and facilities in their disaster preparedness efforts.

Analysis of the Recent Earthquake's Impact on ProP biz Service

While regions near the epicenter experienced shorter lead times for alerts, the data indicated that as the distance from the epicenter increased, the lead times for warnings increased as well. Even a few seconds can be vital in implementing automated control systems via the alert system’s output functions.

Addressing Concerns about Rapid Earthquake Alerts

There is a common concern regarding the efficacy of early warning systems during direct seismic events. In this recent case, the distance between a participating company (Company A) and the epicenter was just about 7 km. Even so, the service managed to provide a notable lead time of 5 seconds due to its application of the PLUM methodology, a predictive approach that enhances warning efficiency.

Following an earthquake, the Japan Meteorological Agency sends out swift bulletins that include essential data like the epicenter's location. While some services may not employ this advanced PLUM technique, ProP biz is fully equipped to utilize it, allowing for timely notifications based on real-time seismic assessments.

What Can Be Achieved in 5 Seconds?

When posed with the question of a mere 5-second lead time, one might perceive it as insignificant. However, surveys conducted by the meteorological agency post-disaster revealed that nearly 70% of earthquake victims expressed a desire for even quicker alerts. This brief window can be critical for individuals to take protective measures, such as shielding their heads or relocating to safer spaces. The timing of the alert is therefore paramount in ensuring safety.
