Namazu Alert

Earthquake information app with push notification.

This is an earthquake alert application with push notifications.

You can browse the latest earthquake information in Japan on your Android

smartphones.

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

out faster.

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.
