As reported by Volcano Discovery
A shallow magnitude 4.3 earthquake was reported in the afternoon near Dillon, Beaverhead County, Montana, USA.
According to the United States Geological Survey, the quake hit on Friday, July 14th, 2023, at 4:26 pm local time at a shallow depth of 6.2 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by The Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 4.3 earthquake as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.3.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Lima (pop. 220) located 2 miles from the epicenter, the quake should have been felt as light shaking.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Dillon (pop. 4,200) located 42 miles from the epicenter, and Saint Anthony (pop. 3,500) 63 miles away.
