A series of explosions reported at 801 Chestnut St. in San Marcos are being investigated by the San Marcos Fire Department with the help of the Texas Railroad Commission.

“Seven surrounding buildings and four food trucks have been reported with some degree of damage,” Fire Chief Les Stephens said during a press conference on Nov.14. “Mochas and Javas had some windows blown up—so far that’s the furthest away we’ve had any reported damage.”

The first call reporting an explosion was at 6:03 a.m. behind Allo Eatery Mobile Food Park. It was followed by a second explosion at 6:20 a.m., according to the SMFD.

No evacuation was needed and no injuries have been reported, Stephens said. The SMFD inspected apartment complexes in the affected area to check for people with injuries.

The fire department has not identified the cause for either explosion, but there is an ongoing investigation to identify the cause; SMPD officials said updates will follow.

The story is developing and may be updated.
