Liputan6.com, Jakarta - On Thursday, June 4, 2026, at approximately 1:47 p.m. Pacific Time, a magnitude 3.8 earthquake struck the Las Vegas area.
The tremors were felt by many residents throughout the Las Vegas Valley, prompting hundreds of reports to the United States Geological Survey (USGS).

Although the USGS put the magnitude of the earthquake at 3.8, initial reports from other sources varied, including a magnitude of 4.1.
The Nevada Seismological Laboratory at the University of Nevada, Reno (UNR) recorded a magnitude of 4.07.
The earthquake's epicenter was estimated to be approximately 7 miles northwest of Summerlin South, Nevada, a residential community located on the western edge of the Las Vegas Valley, near Red Rock Canyon.
The earthquake's depth was recorded at approximately 3.9 miles, or about 6 to 7 kilometers below the Earth's surface.
The Earthquake Impact
The impact of the earthquake's shaking was felt widely, with over 1,000 reports filed with the USGS in the short time after the event.
Most reports came from the Las Vegas Valley, but some also came from Pahrump, near the Nevada-California border.
The intensity of the shaking was mostly described as light, or Level 4 on the Modified Mercalli Intensity Scale.
At this level, the USGS explains that shaking can be felt by many people indoors, shaking dishes, windows, and doors, and causing parked cars to sway.
There were no immediate reports of injuries or significant damage following the earthquake.
Authorities also did not issue evacuation orders or emergency warnings.
Potential Aftershocks
The USGS forecast model indicates a moderate probability of additional seismic activity in the area.
There is an estimated 26% probability of an aftershock measuring 3.0 magnitude or higher.
Meanwhile, the probability of an aftershock measuring 4.0 magnitude or stronger is 5%, and the probability of an aftershock measuring 5.0 magnitude or greater is considered less than 1%.
Regional Seismic Condition
Nevada, including Las Vegas, is known as one of the most seismically active states in the United States.
Southern Nevada has a history of small to moderate earthquakes, although damaging events are less frequent around Las Vegas compared to western Nevada and California.
The Las Vegas Valley itself lies within the Basin and Range Province, an area where the Earth's crust is stretched and fractured by faults, allowing for occasional earthquakes beneath or near populated areas.
