Eleven Mile Reservoir in central Colorado suffered the worst quake in the U.S. this week, according to a U.N. report.

The quake struck at 5:49 p.m.

(10:49 a.m., Friday) at a depth of 3.9 miles (5.3 kilometers).

It was one of two quakes in a region that includes the towns of Tenaha and Colorado Springs.

The U.K.-based International Earthquake Information System reported the earthquake was the strongest quake to strike the area in about a decade.

The first quake, measuring 5.9 on the Richter scale, shook more than 100,000 people, according the U,N.

It was followed by the second quake measuring 7.9.

The earthquake’s epicenter was in Tenaha, where residents reported seeing “large black columns” in the ground.

In Tenaha itself, the town’s mayor told the Denver Post that his town “felt like we were in a movie set.”

The mayor also said he had no idea what was causing the quake.

At least two people were injured in the earthquake.

According to the U.,N., one person was hospitalized after being struck by a car in Tenahas parking lot.

A second person suffered severe head and facial injuries and a third suffered facial and internal injuries.

“We’re still trying to determine what exactly happened,” Denver Mayor Michael Hancock told the AP.

The Colorado Avalanche tweeted, “We are devastated by the earthquake in Colorado.

We are doing everything we can to get the word out.”

The National Weather Service said the earthquake appeared to be an aftershock, which means it caused the ground to shake by itself.

The quakes epicenter is located about 30 miles (48 kilometers) south of Denver.

The last quake in that area was in 2009, when a magnitude-5.4 earthquake struck the city.
