A storage tank filled with fuel exploded early Friday morning near Alton.
Alton Fire Chief Javier Garcia told Action 4 News a fuel storage tank caught fire just after 8 a.m. Friday on Mile 14 and Jarachinas.
Chief Garcia said the investigation is ongoing, but they believe the flames sparked after the top of the storage tank was left open creating a spark.
It took Alton and La Joya fire departments two hours to put out the fire and clear the scene.
Luckily, no injuries were report.
Fire crews responded to a similar fire at the same location a few years ago.
