Fire crews and police are trying to determine the cause of an explosion like sound that rattled homes in several communities in the northwest part of the city.
Around 5 p.m. Tuesday, many people reported feeling their house shake from what sounded like an explosion.
One man who used to live in a mining town says it sounded much like the explosions he used to hear.
The fire department responded to several calls, but say they have not found any signs of an explosion.
EMS says they responded to the area too, but found no one injured.
Back in November of last year several people reported a similar situation with twitter pictures even showing a large mushroom cloud in he far northwest.
In that case the explosion turned out to be some blasting at a gravel pit.
