Experts, please way in as to whether this quake is big enough to mean anything.

The Gulf Coast is sinking into the ocean. That's not a new development. It's been doing it for thousands of years. In some places, like New Orleans, it's more pronounced, often made worse by overuse of well water.

As the coast subsides, it will do so unevenly, and earthquakes will result. It's not the sign of a major earthquake fault. It's just temporary settling of a block of underground rock.

...whether this quake is big enough to mean anything.

For this California native whose family has been in a lot of quakes ... no, a 3.0 quake is not much at all. Around here, it would hardly be noticed. Upper 5s, and anything up to the mid 6s will be pretty noticeable, and 6.5 or higher will be CERTAINLY spooky. A 7.0 or higher ... that's when it starts to get dangerous. But a 3.0? Like a very heavy truck going by on the street.
