POCATELLO -- A series of small earthquakes sent jolts across a corner of southeast Idaho Sunday night.
The U.S. Geological Survey says two smaller earthquakes were also recorded inside the boundary of Yellowstone National Park in recent days.
Temblors of 4.2 and 3.6 magnitude were recorded in the Lava Hot Springs area. Authorities say the jolts generated calls from concerned residents, but so far there is no damage or injuries attributed to the temblors.
Both quakes are considered mild and not strong enough to cause severe damage.
However, Sunday's shaking was pronounced enough to illicit nearly 120 online responses on the USGS "Did you feel it?" website.
Joan Gomberg is s a research seismologist at the USGS field office in Seattle. Gomberg told KTVB that the magnitude 4.2 earthquake was likely felt by many, but not in a large area.
"If you're sitting right on top of it, you might actually feel it pretty strongly," Gomberg said, adding "This is a bit small to cause damage."
Gomberg said around 117 people filled out online surveys on the USGS website above.
Officials say two earthquakes recorded in the northwest corner of Yellowstone National Park were also small -- magnitude of 2.9 and 2.7. One hit Friday in an area 40 miles southeast of Gardiner, while the other was recorded Sunday night closer to West Yellowstone, Mont.
