If you felt the earth move under your feet about 6 p.m. Saturday, you weren’t imagining things.

A 5.3 magnitude earthquake hit about 17 miles east of Soda Springs, Idaho, just before 6 p.m. MDT, sending tremors down to Salt Lake City and surrounding areas, according to the United States Geological Survey. The quake also was felt in Wyoming.

Prior to that, Soda Springs felt a 4.3 magnitude earthquake. Since then, the area also has experienced 11 aftershocks — including one in Lewiston, Utah — ranging from a 3.1 magnitude to a 4.1 magnitude.

There were no immediate reports of damage or injuries, The Associated Press reports.

From surprise to some concern, here are how some Utahns responded to the earthquake on Twitter.

Yep. Draper. Just a couple seconds. If I hadn't felt an earthquake before I doubt I'd've known what it was. — Beka Shaw (@Pippinfett) September 3, 2017

In Park City, thought I felt an earthquake, but dismissed it. Must have been right. — Eric Esquivel (@bdop5) September 3, 2017
