Largest Colorado quake since 1973 shakes homes
The largest earthquake to strike Colorado in almost 40 years has shaken hundreds of people near the New Mexico border.
The magnitude 5.3 earthquake was recorded at about 11:46 p.m. MDT Monday about nine miles southwest of Trinidad, Colo., and about 180 miles south of Denver, according to the National Earthquake Information Center in Golden, Colo. The quake followed two smaller ones that hit the area earlier in the day.
The quake is the largest in Colorado since a magnitude 5.7 was recorded in 1973, U.S. Geological Service geophysicist Amy Vaughn said. That one was centered in the northwestern part of the state — about 50 miles north of Grand Junction, she said.

A magnitude 4.6 quake was felt in the same area at 5:30 p.m. on Monday, and a magnitude 2.9 quake was recorded just before 8 a.m. Two aftershocks - one recorded at 3.5 and another at 3.8 - followed early Tuesday, more than an hour after the 5.3 quake.
The last time the area received such a series of earthquakes was in August and September 2001, when about a dozen smaller-sized temblors were recorded, Chen said.
"The area seems to be active again," he said.
