California has experience three earthquakes in less than 12 hours
The latest quake, measuring a 2.8 magnitude struck Monterey County, which hit at 4:16pm ET.
The US Geological Survey (USGS) detected 2.8 magnitude and 2.9 magnitude tremors just miles outside of San Francisco.
An assessment from Michigan Tech University showed that people typically do not feel quakes with a magnitude of 2.5 or less. Those from 2.5 to 5.4 are often felt but only cause minor damage.
No injuries or damages have been reported following the California earthquakes.
The latest quake came from the San Andreas fault that spans 800 miles up and down California, which experts fear is is overdue for another massive earthquake, according to the Great California Shakeout.
Experts have estimated that over 39 million people on the West Coast would feel the effects of the 'Big One,' which is a magnitude 8 or higher.
Wednesday's earthquake was very shallow depth of 21 miles, but no reports of shaking have surfaced, according to Volcano Discovery.
The two quakes near San Francisco were felt by nearly 2,000 people, according to the USGS' Felt Report that lets locals notify the agency about the quake.
The first hit Dublin around 7:58pm ET on Tuesday and the other was detected near Orinda about six hours later.
These struck along the Calaveras Fault, which is a branch of the San Andreas Fault system, and has been the site of moderate and large earthquakes.
The last major earthquakes on the San Andreas fault were in 1857 and 1906.
The Fort Tejon earthquake of 1857 was a 7.9 magnitude, which caused ground fissures in the Los Angeles, Santa Ana and Santa Clara Rivers.
Trees were uprooted, buildings were destroyed and two people were killed during the event.
The catastrophic 1906 San Francisco event was also a magnitude 7.9 earthquake, which killed 3,000 people and leveled much of the city.
Experts are 'fairly confident that there could be a pretty large earthquake at some point in the next 30 years,' Angie Lux, project scientist for Earthquake Early Warning at the Berkeley Seismology Lab, previously told DailyMail.com.
Dr Sue Hough, a scientist in the USGS' Earthquake Hazards Program, told KTLA5 that there are conflicting studies about what signs precede a major earthquake.
Some research suggested more activity happens before it hits, while others have found there is no warning, she added.
So far this year, California has had 10,159 quakes of magnitudes up to 4.6, 104 quakes between magnitude 3 and 4 and 637 quakes between magnitude 2 and 3.
The vast majority of earthquakes result from the constant movement of tectonic plates, which are massive, solid slabs of rock that make up the planetary surface and shift around on top of Earth's mantle — the inner layer between the crust and core.
As the tectonic plates slowly move against each other, their edges can get stuck due to friction and stress will build along the edges.
When that stress overcomes the friction, the plates slip, causing a release of energy that travels in waves through the Earth's crust and generates the shaking we feel at the surface.
