CHALLIS, Idaho -- The U.S. Geological Survey reports a magnitude 4.1 earthquake shook the ground about 9 miles north of Challis at 6:21 a.m. Thursday.

It's the strongest earthquake reported in Idaho since 2005.

Custer County Sheriff Stu Lumpkin says no damage or injuries were reported, but 911 callers reported the ground shaking up to 45 miles away.

It was a fairly minor event, Lumpkin said. I've only talked to about three people who have actually felt it, but when I was sitting on the bed putting my boots on, it shook the whole bed and rattled the windows in the house.

Dispatchers toldKTVB reports of shaking ranged from the East Fork of the Salmon River to the Elk Bend area.

A magnitude 4.1 earthquake is felt by most people in the affected area, causes noticeable shaking and rattling of objects indoors, but typically causes minimal to zero damage.

Researchers at Boise State University say while Thursday's magnitude 4.1 earthquake was the biggest in nearly a decade, its size and intensity was fairly common.

That's because 68 earthquakes magnitude 4 or larger have been reported by scientists in Idaho in recorded history. In comparison, only 6 earthquakes magnitude 5 or larger have registered in Idaho.

The strongest earthquake -- a magnitude 6.9 on the Richterscale -- was measured in 1983 near Borah Peak, and caused widespread damage along with two deaths.

Boise State University Assistant Professor Jeff Johnson says that's the only earthquake stronger than 6.0 on the Richter scale that's been measured in our state.

In contrast, Thursday's earthquake released ten-thousand times less energy.

Johnson says while clusters of earthquakes have lately been reported in eastern Idaho, it's impossible to draw conclusions about the intensity of future earthquakes based upon it.

Translation:Thursday's earthquake doesn't necessarily foreshadow a disastrous event, but it doesn't preclude it either.

Everything suggests that this is business as usual for this particular part of Idaho, Johnson told KTVB. These earthquakes are not uncommon, and they will happen into the future.
