The 5.3 magnitude jolt struck at 11:46 p.m. local time nine miles southeast of Trinidad, and about 180 miles south of Denver, according to the U.S. Geological Survey.
According to the agency’s website: “The ... tremor caused the most serious damage at Northglenn, where concrete pillar supports to a church roof were weakened, and 20 windows were broken. An acoustical ceiling and light fixtures fell at one school. Many homeowners reported wall, ceiling, floor, patio, sidewalk, and foundation cracks. Several reported basement floors separated from walls. Extremely loud, explosive-like earth noises were heard. Damage on a lesser scale occurred throughout the area.”
The main jolt was preceded by a 4.6 magnitude foreshock at 5:30 p.m., and two aftershocks rumbled during the early morning hours of Tuesday.
There were no reports of injuries from any of the quakes.
The last time such a powerful seismic movement occurred in Colorado was in 1967, when a comparable tremor struck just northeast of downtown Denver.
