I've watched this clip and others like several times and it's still difficult for me to believe how destructive the wave was.
This starts out looking like dirty water being poured out on the drive way until the camera zooms in. Then what looked like twigs and trash is actually homes and cars. If you look careful enough, you can see other cars on the ground driving away as fast as they can.
The weird thing is watching what I think is a house burning in the middle of the water. A huge bonfire going along for the ride.
Video sniped from here.
Pray for the victims of this catastrophe.
