This is an earthquake alert application with push notifications.
You can browse the latest earthquake information in Japan on your Android
Although it is still in the experimental stage, you will also be able to
receive the latest earthquake information with the push notification
feature. However the feature does not guarantee that you will receive
notifications for all earthquakes. Please make sure you use it as substitute
tool when there is no alternative way to find the latest information. You
need to activate this feature first from Setting.
Please note that all the information for recent earthquakes shown in our
lists and push notifications are our initial findings. They may be different
from official information.
About KeepAlive interval
Please try not to change the settings from default. If you change it, push
notifications might fail to reach to your mobile or the battery could run
If your router has NAT timer, NAPT, or TCP timer setting, making Wi-Fi
KeepAlive value about 1 minute smaller than the router's setting could
decrease use of the battery.
About current location issue
There is a chance the distance between your location and the epicentre is
not shown. This is because this app estimates the distance based on your
last location being recognized by Android. So if you have never used apps
which require GPS, your current location cannot be recognized and you will
receive alerts for all areas. The positioning process takes time and
positioning after receiving our alert is too late to reflect your location
on our information.
