San Antonio? That would have been a long way away from the epicenter. Seismic waves must travel far in that part of the country.

I'm not too familiar with Texas geology, but those ancient craton rocks are old and cold.

This is very oversimplified, probably, but heat makes rock softer and, especially if there's also hydrothermal activity or magma present, quakes are dampened.

That's why, here in Oregon, even powerful earthquakes don't have the long reach of, say, the New Madrid, Missouri, temblors in the 19th century that rang churchbells in Boston, Mass.

That said, maybe they were just being cautious in San Antonio in one instance?

The quake could be felt as far away as Carlsbad, New Mexico, and El Paso, and it forced University Health, the Bexar County Hospital District, to vacate a historic downtown San Antonio hospital building after structural engineers declared it unsafe. The more than 100-year-old building was once known as the most modern hospital of its kind in the Southwest.

BTW, they upgraded it to 5.4.

A M5.4 today.

I like this response from someone I don't follow but was liked by someone I do follow (I looked him up):
