Concerned residents in Southern California have been uploading videos to Twitter that show Friday's 7.1 magnitude earthquake shaking water out of their backyard swimming pools.
The quake struck after 8 p.m. local time with its epicenter 20kmfrom Ridgecrest, California, the United States Geological Survey said.
It followed a 6.4 magnitude earthquake on July 4 and took many by surprise.
Residents uploaded footage of the temblor's effects on social media. It looks like wave machines have been installed in the pools as the water splashes and surges over the sides, flooding nearby patio areas.
In the video below, one panicked observer says off camera: "Oh my God" and "Holy c---," while another says: "I don't know if that's good."
The pool below seems to spit water approximately high into the air.
And, here, the quake shoots waves of water away from the pool and toward a nearby house.
The earthquake did not cause any loss of life or serious injury, the local government said in a statement.
