CALIFORNIA was rocked by a magnitude 4 earthquake which hit around eight miles from the Traduco Canyon, but will the residents of California experience any further earthquakes or aftershocks today?
Californian residents were woken up by the tremor at 2.09am this morning (10.09am GMT) which hit 13km north-east of Trabuco Canyon in California.
The earthquake reached a depth of 10km (6 miles) and was felt as far away as Southern California, with people waking up from the tremor.
Actress Chloe Moretz posted on Twitter that she felt the quake and witnesses reported items falling off shelves.
She said: “Whoa. That earthquake just woke me up.”
The earthquake follows just days after a magnitude 7.9 earthquake hit Alaska, which prompted a tsunami warning for the entire US west coast.
The San Andreas Fault system runs underneath densely populated area of Southern California, including San Bernardino, Redlands and Moreno Valley.
A few days earlier, another earthquake hit 3km north-west of Lytle Creek, California on Wednesday at 7.30pm GMT (11.30am local time).
On Tuesday Santa Clara Country was hit by a magnitude 3.6 earthquake at 10pm local time which was felt as far away as San Francisco.
The epicentre of the earthquake was 5.6km (3.5 miles) south-east of Interlaken in Santa California Country in California.
A magnitude 2.7 aftershock hit a minute later on Tuesday, this time 5km (3.1 miles) east of Interlaken.
Will California experience any further earthquakes or aftershocks today?
Each year southern California area has about 10,000 earthquakes, according to the USGS, only several hundred of them have a magnitude greater than 3.0 and only about 15-20 are greater than a magnitude of 4.0.
If there is a large earthquake, the aftershock sequence will produce many more earthquakes of all magnitudes for many months.
The larger the earthquake the more aftershocks it will produce.
USGS said: “The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow.
“These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock.”
A magnitude 4 earthquake is classified as a light earthquake and is felt but only causes minor damage.
It will likely cause some aftershocks after the mainshock, but no further aftershocks have been experienced in the area yet.
Alaska has the most earthquakes in a given year, according to the USGS, with California second on the list.
