LAVA HOT SPRINGS—Two earthquakes hit the Lava Hot Springs area along the Bannock-Caribou County line on Sunday night, according to the U.S. Geological Survey.

The 4.2 magnitude and 3.6 magnitude temblors occurred around 9 p.m. and as of 10:45 p.m. there were no reports of damage or injuries, according to authorities.

The quakes' epicenters were in the area of U.S. Highway 30 at Fish Creek Summit east of Lava Hot Springs.

The earthquakes generated several calls from concerned residents to the sheriff's offices in both Bannock and Caribou counties.

Residents in Lava Hot Springs and Soda Springs said they felt the quakes. There were media reports that the temblors could be felt as far away as Preston and Pocatello.

A 4.2 magnitude temblor is considered to be a light earthquake. These quakes occur up to 15,000 times per year worldwide and consist mainly of shaking indoors strong enough to knock items off of shelves but not capable of causing injuries or serious damage. People outdoors may or may not feel a slight shaking from such quakes.

A 3.6 magnitude quake is considered to be a mild temblor and can still be felt by people indoors but at worst only causes indoor objects to shake. These types of quakes happen over 100,000 times per year worldwide.

Prior to Sunday the last earthquake to hit Eastern Idaho occurred in eastern Caribou County close to the Wyoming state line on March 1 of this year. It was a 4.0 magnitude quake and caused no injuries or serious damage.
