A natural gas tank exploded near the Butter Churn restaurant in Aransas Pass on Thursday.
Aransas Pass Fire Marshal Nate Borrego said the call in at around 6 p.m. for a natural gas tank explosion on Marshall Lane.
The tank was empty when it blew, Borrego said.
Three people were taken to the hospital for non-life-threatening injuries.
No property was damaged in the explosion -- investigators still are looking into what exactly caused the explosion.
