The shallow magnitude 4.1 earthquake was reported just one mile from Temescal, California, according to the US Geological Survey and hit at 10.09am GMT with its epicentre at Trabuco Canyon in California. The tremor occurred at 2.09 am Pacific time at a depth of 6.2 miles. According to the USGS, the epicenter was nine miles from Home Gardens, nine miles from Rancho Santa Margarita, and 10 miles from Corona. In the last 10 days, there have been no earthquakes of magnitude 3.0 or greater centred nearby.
Alarmed LA resident Junaito Moon tweeted: “Downtown LA here. “I was in bed and thought I felt dizzy but realised it was a quake when I saw my lamp moving.” And US weatherman Dan Amarante wrote: “Earthquake in Southern California. “Not a strong one, but enough to wake up a lot of people in the Los Angeles and San Diego Area."

USGS People reported being shaken awake by the violent earthquake
On social media, people reported being shaken awake by the violent tremors, with one person saying there was huge “jolt”. And one resident of Canyon Lake claimed to hear a “loud roaring sound” before the shaking began. But today's earthquake came following a number of smaller ones 6km from Aromas measuring between 2.6 and 3.6 just after 6am. There has been a swarm of quakes in the area this week, with nine tremors of various magnitudes picked up.

The number of tremors in close proximity triggered fears the Big One could be coming. New data has revealed the fault line running through Los Angeles’ exclusive shopping district of Beverly Hills is at risk if 'the Big One' hits. A new map of the region using the latest data from the US Geological Survey shows Beverly Hills – which is situated on the Ring Fire – is at greater risk from earthquakes than previously thought. The Santa Monica fault zone cuts through the so-called Golden Triangle, running between Santa Monica and Wilshire boulevards. The most recent deadly earthquake to rock Beverly Hills occurred just over 24 years ago in January 1994, at a magnitude of 6.7, and scientists believe California’s ‘Big One’ is at least 10 years overdue.
The first shock measured 5.8 magnitude with a second 5.1 shock following shortly afterward. The most recent quake happened at 5.24pm GMT, or 9.24am local time, while the previous quake happened just an hour previously, at 4.39pm (8.39am local time), with a higher magnitude of 5.8. The aftershock of the latter tremor was unintentionally posted as a separate earthquake on the US Geological Survey (USGS) website as separate 5.1 and 5.3 quakes, before being amended. The error was likely caused by another entity such as a tsunami warning agency recording the phenomenon, and a duplicate posting being made.
The USGS told the LA Times it had received a few reports of the 4.39pm 5.8 quake being felt, but said it was unlikely to have affected many people because it occurred far off the coast. Geophysicist Paul Caruso said: "People may feel a little shaking, the chandeliers moving in the house. We wouldn't expect any severe damage." The 5.1 shock also occurred about 100 miles off the coast in the Pacific Ocean. The National Tsunami Warning Centre said there is no danger of tsunami as a result of today’s quakes.

It follows the 4.1 magnitude earthquake which rocked California this morning, and was felt in both San Diego and Los Angeles. That quake was more keenly felt by California residents as its epicentre was on land, 5km north east of Trabuco Canyon in California. It hit at 10.09am GMT, 2.09am local time, and affected up to 10 million people across the state. Tremors were felt in San Diego and the Los Angeles area, with people shaken awake by the violent tremors, with one person saying there was huge “jolt”.

It came less than 24 hours after a number of smaller tremors 6km from Aromas measuring between 2.6 and 3.6. The number of tremors in close proximity this week has triggered fears the Big One could be coming. The name refers to a hypothetical earthquake of magnitude 8 or greater that is expected to happen along the San Andreas Fault. It stems from a 1990 made-for-TV movie that depicts a huge earthquake that destroys all of Los Angeles.
TEMESCAL — A 4.0-magnitude earthquake struck a section of Riverside County today, the U.S. Geological Survey reported.
The temblor hit at 2:09 a.m. at a depth of around 6 miles, its epicenter 1.3 miles south of Temescal and 9.4 miles south-southeast of Home Gardens, according to a computer-generated report from the USGS.
There were no immediate reports of damages, but hundreds of tweets flooded Twitter after the quake, with people in Riverside, Los Angeles and Orange counties saying it shook them awake.
Around the time of the quake, both the north- and southbound Temecula Parkway off-ramps from the 15 Freeway in Temecula were closed to traffic due to a construction crew rupturing a gas line, according to CHP logs, but it was unknown if the incident was quake-related.
