California has experienced three earthquakes in less than 12 hours
The newest earthquake, which measures a 2.8 -magnitude, met Monterey County, which hit at 4.16 p.m.
The US Geological Survey (USGS) detected 2.8 Magnitude and 2.9 Magnitude vibrations only miles outside San Francisco.
An assessment by Michigan Tech University showed that people usually do not feel earthquakes with a size of 2.5 or less. Those from 2.5 to 5.4 are often felt, but only cause minor damage.
No injuries or damage were reported after the earthquakes in California.
The newest earthquake came from the San Andreas error that spans 800 miles up and down in California, of which experts fear, is too late for another enormous earthquake, according to the large Shakeout in California.
Experts have estimated that more than 39 million people on the west coast would feel the effects of the 'big', which is a magnitude 8 or higher.

California has experienced three earthquakes in less than 24 hours. The newest earthquake, which measured a 2.8 -magnitude, met Monterey County, which hit at 4.16 pm, at 4.16 pm
Wednesday's earthquake was a very shallow depth of 21 miles, but no reports of shaking have surfaced, according to volcano discovery.
The two earthquakes in the vicinity of San Francisco were felt by nearly 2,000 people, according to the Vilt report of the USGS with which the local population can inform the agency of the earthquake.
The first hit Dublin around 7:58 pm on Tuesday and the other was detected about six hours later near Orinda.
These broke along the Calaveras error, a branch of the San Andreas error system, and has been the place of moderate and large earthquakes.
The last major earthquakes on the San Andreas error were in 1857 and 1906.
The earthquake of Fort Tejon of 1857 was a 7.9 size, which caused ground gaps 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 event from 1906 from 1906 was also an earthquake with a size of 7.9, in which 3,000 people were killed and leveled a large part of the city.
Experts are 'pretty sure that at a certain point in the next 30 years there could be a fairly large earthquake', Angie Lux, project scientist for earthquake early warning in the Berkeley Seismology Lab, previously told DailyMail.com.
Dr. Sue Hough, a scientist in the Earthquake Hazards Program of the USGS, told KTLA5 that there are conflicting studies about which signs precede a large earthquake.
Some studies suggested that there was more activity before it strikes, while others discovered that there is no warning, she added.
So far, California has had 10,159 earthquakes this year up to 4.6, 104 quakes between Magnitude 3 and 4 and 637 Quakes between Magnitude 2 and 3.
The vast majority of earthquakes is the result of the constant movement of tectonic plates, which are massive, sturdy plates of rocks that form the planetary surface and move on the mantle of the earth – the inner layer between the crust and core.
While the tectonic plates slowly move against each other, their edges can get stuck because of friction and stress along the edges.
When that stress overcomes the friction, the plates glide, creating a release of energy that travels through the earth's crust in waves and generates shaking that we feel on the surface.
