Tremors happed again and again

Today we had tremors many times.

My office is on a sixth floor, so we feel tremors are bigger than on the ground.

The right is yesterday's picture.

We had relatively big quake on yesterday's evening.

(Maybe around magnitude 7 though I don't exactly remember it)

Trains were delayed by around 30 minutes, and it was a little bit crowded at stations.

But it's not so hard to go back home.
