(AP) — A 4.9 magnitude earthquake jolted much of western Wyoming on Saturday, but no damage was reported.

John Bellini, a geophysicist with the U.S. Geological Survey in Golden, Colo., says the temblor occurred at 7:16 a.m. about 45 miles underground. The nearest city is Fort Washakie, about 9 miles east of the epicenter.

Bellini says “it was felt widely in western Wyoming, but this is too deep of an earthquake to cause any damage. … A lot of people might have felt something but they wouldn’t know what they felt because it woke them up.”

The area west of Yellowstone National Park experiences a handful of earthquakes a year.
