**From v1.6, we have experimentally changed the cloud variable server from TurboWarp's server to use this page's own server.

This is the code and English translation of the Real-time Earthquake Viewer project created with Scratch and packaged using the Turbowarp Packager. You can easily push to GitHub Pages, so give it a try. Since the materials are shared on Scratch, the images and audio in /assets are subject to the CC BY-SA 2.0 license.
This is a project that uses cloud variables to receive earthquake and tsunami information in real time.
You can mainly see the following information.
- Earthquake information and the details of the last 9 earthquakes
- Real-time seismic intensity and Earthquake Early Warning Announcments (EEW)
- Tsunami forecast and tsunami observation information
Information is received from DM-D.S.S (a service that distributes data directly from the Weather Service Support Center), so the information will arrive faster than from TV or smartphone apps. There is no guarantee that it will always work though. *Data is updated using cloud variables. Please be careful as it may stop or have bugs. (Only on Scratch)
*It will not work if you are using New Scratcher or are not logged in. (Only on Scratch)
The project works like this (as of v1.3.1). This is what happens when there is a deep earthquake.
If you want to use the screen displayed on this page for distribution, videos, etc., you do not need to obtain individual permission. However, we cannot guarantee the stability or reliability of its operation, so please use it at your own risk.
Inquiries regarding this project can be addressed at the following locations:
The screen changes automatically depending on the shindo level of shaking or earthquake information.
| Operation | Method |
|---|---|
| Enlarge/Reduce | Long press from bottom left button or mouse scroll or double tap |
| Camera reset | Bottom left button |
| Switch tabs on the left | Click the tab icon |
| Scroll tabs | Scroll and drag mouse |
| Restart project (in case of a project breaking bug) | Hold down Z and Q |
- This is different from the seismic intensity announced on TV etc. Equivalent values of seismic intensity observed by strong motion observation networks (K-NET, KiK-net) are displayed.
- Earthquakes that occur deep down can cause shaking in areas far from the epicenter because the shaking is transmitted along the tectonic plates (abnormal seismic area).
- Information is created within seconds after an earthquake occurs, so false alarms may occur.
- Information immediately after an earthquake is detected may have low accuracy regarding the epicenter, magnitude, and predicted seismic intensity.
- Even under normal circumstances, the estimated seismic intensity has an error of about 1 class.
- For earthquakes deeper than 150km, the expected maximum seismic intensity will not be announced.
- Announcements may be made based on actual shaking.
