AUSTIN, Texas – Two people were seriously injured in a house explosion in Southeast Austin Saturday afternoon.

• Crews arriving onscene said the home had "catastrophic damage"
• Two people were recused from the home with significant burn injuries
• Cause of the explosion determined to be buildup of natural gas

The incident happened in the 2300 block of Bendridge Trail.

Authorities said the home had catastrophic damage and crews immediately worked to extinguish the fire and protect the homes on both sides of the explosion site. Firefighters also worked to mitigate a gas line fire that was caused as a result of the explosion. 

A man in his 50s and a woman in her 40s were transported to Dell Seton Medical Center with critical burn injuries that are not expected to be life-threatening. 

Authorities said there was debris between 100 feet and 200 feet in almost every direction due to the blast.

The Austin Fire Department said the home next door suffered significant damage and three adults were displaced. The total damage cost is estimated to be more than $750,000 with at least five other homes and numerous cars being damaged as well.

Fire investigators determined the cause of the explosion to be from a buildup of natural gas. The explosion was so powerful that the force of the concussive wave caused extensive damage to home nextdoor:
