地震 津波の会- ウェザーニュースの地震速報、防災速報アプリ

--------------------------------------------------

Thank you for always using the "Earthquake and Tsunami Association" service.

We regret to inform you that the "Earthquake and Tsunami Association App" will be discontinued on August 31, 2026.

We are deeply grateful for the support and patronage we have received from so many members since the service began in 2013.

The content that you have enjoyed, such as the "Countdown Function," has been implemented as a paid member feature in the earthquake information menu of the "Weather News App."

Furthermore, the disaster mitigation training and disaster mitigation column posts that were conducted through the Earthquake and Tsunami Association App will be gradually implemented and published within the Weather News App.

We apologize for any inconvenience caused by the service termination, and we hope you will use the "Weather News App" in the future.

----------------------------------

*Important* Version 2.0.13 supports the new payment status of the Play Store, which is compatible with Android 4.1 and later. Therefore, users of Android 4.0 cannot use this version.

This application is for paid members (300 yen per month, 3110 yen per year) and allows you to check the following information at any time.

[Earthquake and Tsunami Information Menu]

◆ Immediate Notification to Your Location Upon Earthquake Detection

Emergency Earthquake Early Warning Service "The Last 10 Seconds"

Immediately after an earthquake, observational data captured by seismometers near the epicenter is analyzed. Based on GPS location information, the seismic intensity and arrival time at your location are estimated and communicated as quickly as possible.

Furthermore, you can set your device to sound the emergency earthquake early warning even if it's in silent mode.

When the app is launched, an audio countdown will notify you of the earthquake's arrival.

(Please note that using location information (GPS) in the background may increase battery consumption.)

◆ Rapidly Connected "Earthquake Information" and "Tsunami Information"

We provide the latest earthquake information (epicenter, magnitude, seismic intensity in various locations, etc.) and tsunami information (predicted tsunami height, estimated arrival time, high tide time, observed values) faster and more detailed than anywhere else.

You can also check and report information regarding earthquake tremors from the field in real time.

◆World's First Tsunami Radar Information Capable of Observing and Tracking Tsunamis Every 2 Seconds

Weathernews has independently developed a "tsunami radar" to observe and track tsunamis, with the aim of mitigating damage caused by tsunamis. Based on the tsunami observation data, in the event of a large tsunami, its approach and arrival can be visualized, making it useful for disaster prevention and mitigation.

◆Latest Information Delivered During Earthquakes and Tsunamis: "Announcements from the Geophysical Center"

The Weathernews Geophysical Center, which monitors geophysical phenomena around the world 24 hours a day using tsunami radar and other infrastructure, will provide disaster prevention and disaster information regarding earthquakes and tsunamis as needed during emergencies.

◆Regular Connection Tests and Operation Checks with Members: "Disaster Mitigation Training"

To ensure that our infrastructure "always connects quickly" even during earthquakes and tsunamis, we conduct regular connection tests with our members. Based on the results, we proceed with improvements to the app and strengthen our servers.

◆ "Disaster Mitigation Column": Learn about the latest initiatives related to disaster mitigation and deepen your knowledge of disaster mitigation.

◆ "Announcements & Developer Blog": Share important information with members, such as disaster mitigation training schedules and bug fixes.

This "Earthquake & Tsunami Association" is designed to provide members with an infrastructure that "always connects quickly" even during earthquakes and tsunamis. We conduct regular connection tests with members, appropriately increase dedicated servers as needed, and build new infrastructure and services as our membership grows. By keeping you constantly connected to the "Earthquake & Tsunami Association" network, you can grasp detailed situations in real time even during sudden earthquakes and tsunamis, enabling you to take swift personal disaster prevention and mitigation actions and contributing to damage reduction.

Note: During the issuance of earthquake warnings, tsunami warnings, and other information, congestion may occur due to restrictions imposed by mobile carriers. Therefore, we recommend connecting via Wi-Fi to ensure smooth use of the "Earthquake & Tsunami Association."
