The earthquake information service that the Japan Meteorological Agency has newly started providing.
Immediately after an earthquake occurs, based on the observation data captured by seismometers close to the epicenter, we will predict the intensity of shaking at your location a few seconds to several tens of seconds before strong tremors arrive and notify you. This allows you to take disaster prevention measures before the significant shaking reaches you. *The emergency earthquake alert service is available as an option for Lightning Scope.*

basic information
◆◇◆Prediction Principle◆◇◆ Immediately after an earthquake occurs, the initial tremors (P-waves) are detected by seismometers near the epicenter. Based on this observational data, the magnitude of the earthquake and the location of the epicenter are estimated right away. Shortly thereafter, information is transmitted to customers' devices via communication lines, and before the arrival of the main shock (S-waves) that causes strong shaking, the estimated seismic intensity at various locations and the time until the main shock arrives are calculated instantly. ◆◇◆Differences from Conventional Earthquake Information◆◇◆ The significant difference between emergency earthquake alerts and conventional earthquake information is their speed. Emergency earthquake alerts provide several pieces of information within a few seconds to about a minute after detecting an earthquake. The first report prioritizes speed, and the accuracy of the information provided subsequently gradually increases. ◆For more details, please contact us.

Company information
Franklin Japan has been operating the Japan Lightning Detection Network (JLDN), the first and only nationwide lightning observation network in Japan, since October 1998. JLDN networks sensors installed across the country and utilizes accurate time information sent from GPS to observe the location, time, and current value of lightning strikes. The observation accuracy of JLDN boasts a capture rate of over 90% within its coverage area, with a location error of less than 500 meters, making it arguably the best lightning observation network in the world currently available. The observed lightning strike data is utilized in real-time for power management in factories, maintenance of networks, and protection of human life in outdoor sports.
