The fact that the quake had a thrust component was likely the reason for

Check out the beach ball:

Ok, now I'm getting a bit more confused, but at least I have an idea of
what I need to learn. Progress is good. Thanks, George.

Moment tensors - a new concept to me (Wiki helps). I assume the raw
data comes from seismometers scattered around the globe, since the
article indicated the USGS doesn't actively monitor the Gulf region?
Also, does the "ball" just cover the region circled on the map, or is
it the entire planet?

Did somebody say beachballs?
