was reading in a park in suburban tokyo a few years ago, notifications arrived for the noto peninsula earthquake.

kids in the park stared doing wobbly knee dance :D

felt the quake about 30sec later.

The one in 2024? I was in Tokyo at that time but we didn't get any notification nor felt anything :/

How much warning did you get? I mean in minutes or seconds?
reply
Depends on the location, the alert comes usually as soon as the initial tremors are registered. If you're at the epicenter, tough luck. For example, for me in Tokyo, the alert came 2 minutes before it hit, and even then, the actual earthquake was extremely subtle.

In our case I guess we got the warning 10~20 seconds before the earthquake? I don't know, I didn't count it xD

I use NERV, it gives you a countdown timer and i like to know whether to prepare or not
