What caused the earthquake in Utah?
The quake appears to be the result of normal movement on the Wasatch fault system, a region of regular seismic activity that stretches for about 240 miles (390 kilometers) north-south along Utah’s Wasatch mountains, the USGS said.
What caused the earthquake in Utah 2020?
The epicenter of the shock was located in western Colorado, 3 miles south-southwest of the town of Bedrock, Colorado, and 18 mi east of the town of La Sal, Utah. This earthquake occurred within an area of frequent small, shallow earthquake activity triggered by underground saltwater injection.
Does Utah have a fault line?
The Wasatch Fault parallels the western base of the Wasatch Range for approximately 350 km (220 miles), from near Fayette, Utah in the south to near Malad City, Idaho in the north. The Wasatch Fault is also known as the Wasatch fault zone (WFZ) since it isn’t a single long fault, but rather a series of fault segments.
How many earthquakes has Utah had in 2020?

Is Utah overdue for an earthquake?
Studies indicate that Utah is due or overdue for a devastating earthquake (Utah Geological Survey). These studies show that the central most active part of the Wasatch fault has averaged one very large (magnitude 6.5-7.5) earthquake about every 270 years.
How overdue is the Wasatch Fault?
In fact, the Wasatch Front is about 100 years overdue for a major earthquake.
How likely is an earthquake in Utah?
During the past 6,000 years, large earthquakes have occurred on the Wasatch fault on the average of once every 400 years, somewhere along the fault’s central active portion between Brigham City and Levan. The chance of a large earthquake in the Wasatch Front region during the next 50 years is about 1 in 4.
How overdue is Utah for an earthquake?
about 100 years
“We still have a 50\% chance of a 6.5 or up to a 7 magnitude quake here along the Wasatch Front in the next 50 years,” warned Wade Mathews with Utah’s Division of Emergency Management, who oversees the state’s “Be Ready Utah” initiative. In fact, the Wasatch Front is about 100 years overdue for a major earthquake.
How likely is Utah to have an earthquake?
A moderate-sized earthquake that occurs under an urbanized area can cause major damage. Magnitude 5.5 – 6.5 earthquakes occur somewhere in Utah on the average of once every 7 years.
