Many residents of San Antonio were startled by dull, repetitive booming sounds on the night of April 13th. Strange and disturbing sounds have been emanating from the Earth in destinations all over the world for a few years now, and Texans have heard them, too. Could this be related? Probably not (read on)...
Here's the account from a forum member on Godlikeproductions.com:
I live on the northeast side of San Antonio. About 30 minutes ago, while watching Game of Thrones, my wife and I began to hear strange booming sounds outside. We walked out the front door and saw our next door neighbors in their yard. They said, "It's not us." It wasn't because the sounds were coming from the opposite direction.
While this was no doubt an eerie experience for this couple, it appear we might have a reasonable explanation: fireworks. Although the witnesses didn't see fireworks (and they looked for them), all month long there are parades and celebratory events going on in San Antonio as part of the annual Fiesta San Antonio.
Here are some other thoughts on the matter:
