An earthquake hit Colorado overnight near the New Mexico border.
The magnitude 5.3 quake was the largest to strike the state in almost 40 years.
People from northern New Mexico all the way to Colorado Springs, Colo. reported feeling the temblor.
The quake followed two smaller ones earlier in the day.
"I thought maybe a car had hit my house," 70-year-old Trinidad resident Nadine Baca told The Associated Press. "Then I called to my son and he said it was the third (quake) today."
Authorities said just a few homes were damaged in Tuesday's quake.
