ProP biz Earthquake Alert System Supports Preparedness After Aomori Quake

On December 8, 2023, at approximately 23:15, a significant earthquake with a maximum intensity of 6 was registered off the coast of Aomori. This seismic event primarily affected Hachinohe City, experiencing a strong level of 6, while other areas from Hokkaido to the Kinki region recorded tremors ranging from level 6 weak to level 1. Long-period seismic motions at class 3 were also observed in the Sanriku area of Aomori Prefecture.

Our heartfelt sympathy goes out to those affected by this disastrous event. It is essential for residents in the regions that felt strong tremors to remain cautious over the upcoming week, as the likelihood of aftershocks at similar seismic levels remains heightened. Meteorological agencies have indicated a potential for even stronger quakes in the days ahead, necessitating vigilance in monitoring earthquake activity.

In response to this quake, the Japan Meteorological Agency (JMA) issued an earthquake warning at 02:00 on December 9. This marks the first issuance since the launch of the alert service in December 2022. According to JMA, the earthquake's occurrence has increased the relative possibility of a major seismic activity along the expected earthquake source area between the Nemuro region in Hokkaido and Sanriku in Tohoku.

ProP biz Earthquake Alert Service

Provided by Nankai Densetsu Co., based in Osaka, the ProP biz emergency earthquake alert service plays a crucial role in enhancing disaster preparedness by distributing predictive information before seismic waves reach affected areas. This service, which can be beneficial for various institutions such as factories, schools, and offices, allows users to implement preventive measures by triggering alarms or controlling systems prior to strong ground movements.

Features of the Service

ProP biz offers several unique features:
1. Long-period seismic motion compatibility: The service predicts and displays specific vibrations caused by high-rise buildings, a common concern in urban areas.
2. Redundant delivery system: Simultaneous data distribution is facilitated through data centers located in both Tokyo and Osaka, ensuring reliability during disasters.
3. Monitoring service: ProP biz includes 24/7 operational surveillance of receiving devices, with alerts sent for any errors detected.
4. Onsite maintenance: Nankai Densetsu personnel are available for equipment repairs and replacement during business hours.

Long-period Seismic Motion Compatible Model S740-PL

In their service, Nankai Densetsu employs the S740-PL model developed by Meisei Electric Co., a leading entity known for its high sensor technology. This model is instrumental in calculating the estimated seismic intensity, the estimated lead time before tremors reach, and classifying long-period seismic motion using data from the JMA.

Through this service, facilities can link emergency notifications with elevators and public address systems to prepare for seismic disturbances effectively.
