interesting technology & results.. BUT
BUT....
the reality is what of what would make a difference in 2 minutes.
Okay, I will admit to having NO experience in/with earthquakes and perhaps 2 minutes is very significant
My post is not meant to be critical .. just inquisitive. Can 2 minutes help?
For me, it was just enough time to move quickly away from a big plate glass window and make sure nobody else got near it.
If it had struck closer to Tokyo, hey, who knows?
I'll take any amount of time for advance warning. Even two minutes.
2 minutes is enough time to get yourself and/or kids under a table, away from windows or other hazardous furniture/lighting, out of weak structures, etc...
I too, have no experience with earthquakes first hand, so I’m just guessing, however, I saw a TV show on earthquakes a while back - history channel I think - and they showed where by the time one hits you may not be able to make it under a table if the quake is strong enough...
I’ve only experienced one moderate quake (5.1, Oregon, 1993). They say most injuries are due to things falling on top of people and cut feet from running across broken glass. A 2 min. warning might give one time to move away from potentially hazardous falling objects or get one’s shoes on. If you were driving, it might mean time to pull off the road safely.
We had several pretty good jolts in Taipei over my years there. 2 minutes warning would be very welcome and likely save many lies.
One can get in at least the best nearby area for protection from falling stuff and crunching buildings. If one is well prepared with a bugout-provisions bag—one can grab that to insure it’s nearby. If one is trapped for days, water and food can be rather welcome.
