ProP Biz Emergency Earthquake Alert Service: A Lifeline in the Recent Ibaraki Quake

On June 16th at approximately 7:46 PM, a sizable earthquake with a maximum intensity of 5 weak jolted the southern Ibaraki region. The tremors were felt in five municipalities, including Ota City and Chiyoda Town in Gunma Prefecture, as well as Kazo City, Honjo City, and Misato Town in Saitama Prefecture. Areas across a broad region, from Tohoku to the Kinki area, recorded varying tremor intensities from 1 to 4.

The impact of such seismic activity echoes deeply in local communities. As we extend our heartfelt sympathies to those affected by the quake, it is essential to highlight the role of advanced technologies, such as the emergency earthquake alert service offered by Nankai Electric Company. This service, known as ProP Biz, is designed to provide timely warnings that can help businesses and facilities implement effective disaster preparedness strategies.

ProP Biz and Its Role in Earthquake Preparedness

ProP Biz has been crucial in providing alerts that precede the arrival of earthquake tremors. By utilizing real-time seismic data, the service can notify users about the expected time until tremors hit their location. This feature is particularly important for industries and facilities situated in proximity to earthquake epicenters, such as the recent earthquake in Ibaraki.

A key advantage of ProP Biz is its ability to quantify the 'warning seconds' before tremors arrive. For users closer to the epicenter, the warning time is significantly shorter. However, as one moves farther away from the source, the warning time increases. Even a matter of seconds can provide vital opportunities for automated responses in facilities, thereby minimizing damage and ensuring safety.

How ProP Biz Calculates Warning Time

One of the defining features of ProP Biz is its ability to assess and communicate how many seconds remain before the shaking reaches a specific location. This is achieved by pre-registering the latitude, longitude, and surface ground amplification ratio for the receiving terminal, thus enabling the calculation of estimated seismic intensity and warning time based on source information provided by the Japan Meteorological Agency (JMA).

By providing location-specific alerts, ProP Biz reduces panic and enables users to execute appropriate safety measures through the suggested actions correlated with the available warning times. Here are examples of actions based on different warning times:

- 3 seconds: Protect your head and take cover
- 20 seconds: Turn off gas and open evacuation route doors

This capacity for granularity in alerts allows for more rational and effective disaster response strategies.
