It struck near in the Mojave Desert, about 150 miles northeast of Los Angeles, but people report feeling it as far as Las Vegas and California's Central Valley.
From those who witnessed serious damage, to those who were just upset about spilling their cereal, the "Twitterverse" is erupting with reactions.
Here's a sample from every end of the spectrum.

I was on the elliptical when that earthquake happened it was so rocky that I thought I was just that out of shape.— Chrish (@mistachrish) July 4, 2019
Some people are telling their story through their pets.

tfw a single crumb hitting the floor sends you sprinting across the house but an earthquake doesn’t disturb you pic.twitter.com/35P5BkGd9C— Mina Kimes (@minakimes) July 4, 2019

Nice little earthquake here, but I’m not so sure that was small. I was fixing me some cereal and almost fell over 😂— Terri McDonald (@FightforCF) July 4, 2019
This one actually felt weird, kind of like a stop and start again.
Who else felt it!
