When I sat at the gate waiting for my flight, i felt a constant shaking of the ground and the seat. Like waves crashing on beach.
There is no earthquake warning.
I wonder how this happened ?
Is the structure allow it to be like that?
The airplanes taking off and landing ??
Or the metro underground ?
Is it related to the sinking issue?
Or totally something else
Just pure curiosity.
