Atocha, Bolivia — A magnitude 4.5 earthquake struck southwestern Bolivia on Thursday night, the U.S. Geological Survey reports.

What happened: The quake hit at 9:45 PM Central time (10:45 PM local time), centered about 36 miles southwest of Atocha in the Potosí department. It struck very deep — about 147 miles (236 kilometers) below the surface.

Impacts: Very deep earthquakes like this one rarely cause damage or strong shaking at the surface. The USGS lists no felt reports, and there is no tsunami threat from an inland quake of this size and depth.

What to do:

- If you feel shaking, drop, cover and hold on until it stops.

- Stay away from windows and anything that could fall.

- After shaking, check for hazards such as damaged walls, gas smells or downed power lines.

- Expect possible aftershocks and stay alert for updated guidance from local authorities.
