Southern California has experienced multiple earthquakes within just one hour.
The US Geological Survey (USGS) detected three tremors starting around 1:15am PT, ranging in magnitude from 3.5 to 3.7.
The largest hit occurred around 2am PT, 13 miles outside Rancho Cucamonga.
More than 2,000 people have reported shaking to the USGS since the first earthquake struck, with many located in Los Angeles.
Residents have shared their experiences on X, with one saying: ‘Pray for us in California that the big one doesn’t happen.
‘That was the 3rd earthquake in the last 10 minutes.’
Others said the earthquakes woke them up as they struck in the middle of the night.
These earthquakes follow another magnitude 3.5 earthquake that shook the Rialto area late Tuesday afternoon, which is just miles from Wednesday’s seismic activity.

The first quake, a magnitude 3.5, hit about 3 miles southeast of Ontario at a depth of four miles.
A second 3.5 tremor struck the same area just over 10 minutes later.
‘Felt both of those here in Ontario Ranch. The second one felt more violent than the first. Both are quick and strong jolts,’ resident Nancy Pacheco shared on Facebook.
Cynthia Villalobos said the second earthquake was strong enough to shake her entire home.
About an hour after that, a stronger magnitude 3.7 quake rattled an area north of Lytle Creek, striking at a depth of 6.5 miles.
Many residents across the High Desert and Inland Empire said they heard a deep rumble just moments before the sharp jolt hit.
A smaller magnitude 2.1 micro-earthquake was recorded near Lytle Creek shortly after the larger one was detected.
So far, there have been no immediate reports of significant damage or injuries.

The earthquake swarm likely occurred along a secondary fault trend, often referred to as the Fontana Trend, situated just west of where the major San Jacinto Fault Zone and Sierra Madre Fault come together.
Experts described this seismic activity as shallow, left-lateral motion on smaller fault strands rather than on the main San Jacinto or San Andreas lines.
On Tuesday, a magnitude 3.5 earthquake struck near Fontana around 4:54pm, shaking parts of the Inland Empire from a depth of 3.6 miles.
The USGS received nearly 2,000 reports of shaking after the quake struck.
