KXAN obtained video of the scene. It shows a fire still burning, debris—including a large pile of wood—scattered throughout the area, what appears to be a burned-out vehicle, and damage one or more homes. "AFD crews are extinguishing small spot fires in the collapsed debris. Several neighboring houses were damaged," AFD said. "1 house completely collapsed 1 house partial collapse." The explosion's "boom" was heard and felt in the areas as far as Cedar Park and Leander, according to KXAN viewers. "We are aware of the loud 'boom' that was heard and felt throughout the city," Cedar Park Police said in an X post. "We received reports that there was an explosion, but it was in the Austin area." Texas Gas Service crews were on the scene responding to the incident and confirmed the home did not have access to natural gas services.
