I grew up in East Texas, and if we ever had any earthquakes, I don't remember hearing about them. Many of the lakes, though, were formed a few centuries ago by some pretty big shakers. Probably just coming out of a lull.
Unless I'm mistaken, there's only one natural lake here. The rest are reseviors that have been created in the last ~100 years.

Thank God no one was hurt by those earthquakes, although they seem pretty minor. Texas is on fault lines, earthquakes are to be expected from time to time.

Christchurch in new zealand has had thousands of earthquakes over the last year. has it occured to the op that the ac might not be american or even caucasian.

There are many natural lakes in East Texas. Most are smallish oxbow-shaped bodies formed when a river jammed up or changed course. Caddo Lake supposedly was formed from an earthquake in the early 1800s, but it's also possible that a log-jam downriver created it.
Here is another article about the earthquakes that says there is nothing surprising about them:
John Carr is a geologist with Carr Enterprises, and he's been following the last two earthquakes that occurred here in East Texas.
"This is a natural event, it's on a very large existing fault system that's called the Mount Enterprise System.
The last quake we're told had it's epicenter, right along the fault line, and the one that occurred Thursday morning just a few miles east, also on the fault line. Also, we're told last week's shake up, was called a foreshock.

I really want to know... what is the significance of unusual, but very small, earthquakes.
.
Is there a bigger issue at stake?

There's no significance in most cases since small earthquakes happen all the time. The ones that would be significant wouldn't be unusual, since they lie along known active faults such as New Madrid or San Andreas.
We seldom have earthquakes here. By seldom, however, I don't mean never. We've had two in my lifetime, about 40 years apart. So, by definition of the term, any earthquake we have is unusual, so to say our latest earthquake was unusual is to simply state the obvious.
Sounds like that's about the state of things in this part of Texas.
