It's located in Texas.
The impact from this explosion was felt up to 50 miles away, and in the town itself, devastation .

the West fertilizer plant at the small town of West, Texas, about 20 miles from Waco, exploding.
A blast and the massive fire that followed living dozens of homes and buildings heavily damaged or destroyed.
The town's mayor telling CNN what it felt like.
I've never seen any explosion like that.
It's just a ball of fire, just went up like a nuclear bomb went off.
Big old mushroom cloud.
The blast was strong, it registered as a magnitude 2.1 earthquake.
Half of the town's 2,600 residents were forced to evacuate .
Officials concerned about potentially deadly gas fumes and a second fertilizer tank that could also explode.
People living near the plant feared for their lives.
When it exploded, we all just hit the ground, and I was trying to cover up our daughter, because there was a lot of debris flying.
And then after that, it was just basically search and rescues.
The smoldering fire and fumes prevented rescue workers from getting near the plant, officials say the blast area resembles a war zone.
Authorities say they're not ruling out the idea of criminal activity,
but they didn't have any evidence yesterday that indicated anything criminal.
There were some concerns about a substance, though, called anhydrous ammonia.
It's a gas that's used to make fertilizer.
The fumes from it can cause irritation, even suffocation .
When it's mixed with water like water in the human body, it can cause severe burns, so officials were worried about people being exposed to it.
The explosion Wednesday night sent out a shock wave.
People who were blocks away were knocked to the ground.
Houses were destroyed or severely damaged.
