STEAMBOAT SPRINGS, COLO. (AP) -- Authorities say a small earthquake hit near Steamboat Springs but no one has reported feeling it.
Colorado state geologist Vince Matthews said the 2.8-magnitude quake struck just after 6 a.m. Wednesday. The Steamboat Pilot & Today reported it was centered about 15 miles south-southwest of Howelsen Hill Ski Area.
Matthews said the earthquake originated about 1 kilometer below the surface, which could mean it was triggered by mining.
He said the geologist at the Twentymile Coal Company didn't report feeling the quake either.
A 4.4-magnitude quake shook buildings in the area in September 2005. A 2.2 quake followed about a week later.
