How to report earthquakes in the US

The U.S. Geological Survey says it has detected a magnitude 4.2 earthquake in central Utah, about a mile northeast of downtown Salt Lake City.

The quake was felt about 50 miles (80 km) northeast of the city.

A magnitude 4 earthquake is considered the strongest in the U.A.M.S.; a magnitude 5 quake is considered a moderate to severe earthquake.

The USGS says the quake was centered about 6 miles (10 km) east of the town of White River and about 5 miles (8 km) northwest of White Valley.

The quake was shallow, so it could have been felt in other areas of the Umatilla Valley, including in the state of Nevada.

The Utah Geological Survey said it’s likely that the earthquake was a shallow one.

It was centered at about a magnitude of 4.6, which is weak but not catastrophic.
