Colwich, Kan. -- Westar Energy says an explosion that was heard and felt around Maize and Colwich early Monday afternoon was part of routine work near the Gordan Evans Energy Center.
"What it is: We are actually splicing together transmission lines," Westar spokesman Nick Bundy said.
Around 12:30 p.m. 911 dispatchers started receiving calls from residents around Maize and Colwich reporting what sounded like loud explosions that rattled their homes.
"It felt like it shook the ground, you know, like it was some kind of boom," a caller told dispatchers.
KAKE News also received phone calls in and messages on our Facebook page asking what the explosion was.
Westar says the explosion was actually an an implosion detonation used to connect power lines together.
"This implosion method they are using is a lot stronger than other splicing methods. When they get done and check the wire they can't the different between where it was spliced and the normal line," Bundy said.
Westar says the implosions do not pose any danger to the public. The do notify people who live in a one-mile radius of the implosion site before a project begins. They've been performing these implosions in the Colwich area for about two weeks now.
But experts say weather conditions were just right Monday afternoon to allow the sound to travel farther than perhaps it normally would have.
They say the work is expected to be done before the new year so there is a possibility, although not likely, that people could here another implosion Tuesday.
On their Facebook page, the company posted this video, which demonstrated the process.
