Authorities say a meth lab is the reason behind an explosion that occurred in Tacoma, Washington early Monday morning, reported.

The blast occurred around 2 a.m. after two people began cooking meth in a trailer behind a home.

"It made the whole house shake. Things fell off the wall. It was like a sonic boom and felt like an earthquake," neighbor John Morris told

One man was rushed to the hospital for serious burns. Though he initially suggested the fire was caused by a heater, he later admitted to investigators that it happened while cooking meth.

Police are still searching for a second man, badly burned, who was able to run from the scene. Tacoma Fire Battalion Chief Dave McRoberts said hospitals will notify authorities if anyone with severe burns is admitted.

Due to the flammable chemicals, a hazmat team is assisting firefighters in the rubble and nearby residents were advised to keep their windows closed.

On Sunday, two people were arrested and hundreds were evacuated from a housing complex after a meth lab was discovered in Boston.

The Massachusetts State Police Bomb Squad was called after Ronald Royse, 46, and Joanna Miles, 44, tried cooking meth in one of the apartment units.

Many of the residents in the apartment are senior citizens.

"It's very unstable. I mean, you don't cook something like that in senior housing," one resident told WCVB-TV.

Residents were not allowed back in the building until Monday morning.
