We noticed that here have been 2 earthquakes in the GOM
(one today greater than 5.8 Richter) in the past 4 months.
These are highly unusual and impossible for operations
to plan against.

The GoM is a big place, Magnitude 6 earthquakes happen almost everywhere almost all the time on the timescale of oilfield operations, you don't use rigid structures in deepwater, pipelines are routinely engineered for earthquake tolerance, and tsunamis are imperceptible in water depths of more than a few hundred feet.

Next question?

Yes But:
There is a pressure wave that extends from the sea floor to the surface moving at 500 MPH that is no doubt not perpendicular to the sea surface. If it displaces the ocean water by 6 inches what effect does it have on a mile of drill string or production type tubing? Does the string ring or resonate at some freq and snap at the ocean floor or at the surface or some were between? I agree it is imperceptible on the surface do to inertia and the mass of the vessel.
