Not the OP, but will answer: far enough from a black hole, the gravitational field strength of a black hole is no different from that of any other object of the same mass. For example if the Sun right now were replaced with a black hole of the same mass, the Earth's orbit would be unchanged.

Its only when you get close to the event horizon of the black hole does Einstein's General relativity have to be used instead of plain old Newtonian gravity to describe the behavior.

In the cheesy action movie San Andreas ,starring the Rock, there is a massive earthquake on the San Andreas fault , apparently squarely on land. An hour into the movie a tsunami hits the coast of California.

Given that the earthquake energy was on land and the energy spreads outward, shouldn't like Japan have been hit by the resulting tsunami, not the point of origin, California??
