Fort Carson says a training exercise on post is responsible for the loud booms that kept many people awake Thursday night in Colorado Springs and for a big boom and shake that rattled nerves in Cañon City late Friday morning.

The training is scheduled to continue through Labor Day weekend, so more noise can be expected.

The post provided the following statement about the training exercise on Friday afternoon:

"The 3rd Armored Brigade Combat Team, 4th Infantry Division, is conducting field training now through Sept. 1 on Fort Carson. The training includes day and night live-fire exercises that will incorporate armor, artillery, mortars, aviation training, Bradley Fighting Vehicles and Abrams tanks. Increased noise and dust levels from this training exercise can be expected throughout the training period due to live-fire events and heavy vehicle transportation. This training is crucial to the readiness of our Soldiers to train like they fight for any future contingencies."

Fort Carson says anyone who would like to leave a noise complaint can call 719-526-9849
