"strat" was basically correct. The seafloor changes location - it is displaced from where it was. The displacement can be compressional, tensional, or lateral (or a combination of lateral and another motion).

In this case, the seafloor on part of the fault-zone that moved, was raised as much as 10 meters. Think of what might happen if the bottom of a swimming pool was suddenly thrust up 10 inches - there would be a big wave of water spilling out over the edges. Now think of that on an oceanic scale with a few ten of thousands of square miles of ocean floor being thrust up as much a 35 feet.

Thanks much. Have wondered about whether the sea floor was raised or lowered 20 feet or so.

I totally understand now, I have an excercise/lap pool that I often displace water out onto the floor by the waves I make.

The waves end up bowling around the curved edges and lap over onto the floor in the shallow/step area.
