Were you scared last night? You may have thought about that was the end of the life. If you got stuck inside the building, you will shout out. But your voice may not loud enough. You should have a whistle at your house. You would survive even if your flat collapsed. Somebody hear your whistle.
When earthquake hit, you must get up immediately and take distance from heavy big furnitures first. Then, think about where is the most safe place. Inside the flat, perhaps, bathtub could be the safest from my personal view.
The earthquake level last night (Mg 4-5)was OK it occurs everywhere as usual. If you felt more, get serious!
I guess, you were frightened last night. Mg 6-7 is pretty different. That's another level. You will hear women' scream from everywhere. Fridge and washing machine would fall down.
Foreign people sometimes say, "Japanese love brand new things." Apparently, earthquakes and floods that renew our environment often. The desasters force us to renew.
Anyway, prepare what really needs with you when you get out from your flat suddenly.
Good night, x
