Felt it all the way in Tokyo!

There is this amazing app called NERV that, whenever there is a large earthquake anywhere in Japan, sends you an early warning push notification and an animated display with shockwaves emanating from the epicenter, plus a countdown timer for the first wave hitting you. The first it went off for me it felt like something out of sci-fi. I think I got 45 seconds this time before my apartment started shaking.

>NERV

Does it play appropriate Evangelion OST track depending on magnitude though?

45 seconds is an incredible accomplishment. That’s a decent amount of heads up to get safer place. Obviously nerve wracking but great progress in alerts

Receiving one of those sounds really scary.

I didn't feel a thing a bit south of Nagoya. Almost strange that there was nothing here, when you got shaking in Tokyo.

How do you use your 45 seconds?

How many stories above the ground, and might you guess at your building's construction (wood frame, steel frame, etc.) and foundations (on bedrock, on loose sediments, etc.)?
