A large explosion at an oil refinery near the Texas coast on Monday (March 23, 2026) shot plumes of smoke into the air and forced nearby residents to shelter in place, according to officials.
No one was injured in the explosion at the Valero refinery in Port Arthur, about 145 km (90 miles) east of Houston, Mayor Charlotte M. Moses said. She urged residents in parts of the west side of the city to stay put, saying fire fighters had arrived.
“There's been an explosion, yes, but we're OK; everybody's OK," she said. "They're trying to put the fire out as quickly as possible.”
The explosion comes amid a spike in gas prices driven by uncertainty over the global oil supply because of the Iran war.
The refinery has about 770 employees and can process about 4,35,000 barrels of oil per day, according to Valero’s website. The plant refines heavy sour crude oil into gasoline, diesel and jet fuel, according to the website.
