Dr. Lucy Jones, a seismologist, founder & chief scientist at her center, said it is one of the largest swarms we have had in the Imperial Valley - and it is historically the most active swarms in Southern California.
Several swarms of earthquakes occurred near San Andreas.
Wednesday evening from around 4:30 p.m. to 6:05 p.m. there has been an M4.4, M4.9, and most currently a M4.2.
Jones said they are too far from the San Andreas fault to change the probability of a quake on it.
No tsunami warning has been issued yet. Meanwhile, people living in South Africa have been reporting tremors.

Tremors were felt in Leighton Buzzard for the fourth time in two weeks
Tremors were felt in Leighton Buzzard for the fourth time in two weeks
A magnitude 2.1 event struck at 1.39pm on Tuesday afternoon, just over four hours after a 3.0 tremor was felt in the Bedfordshire town at 9.32am.
Geologists said they were likely to be aftershocks of the first quake felt in the area on 8 September.
"There's obviously been some stress been building up in that particular area and we've had the initial earthquake," said Glenn Ford, a seismologist with the British Geological Survey (BGS). "It's maybe just still rebalancing the stress regime in that particular part of the world and we're getting these little aftershocks occurring as well."
The 8 September tremor was magnitude 3.5 and the first aftershock five days later measured 2.1.
According to the BGS, residents said Tuesday's first tremor "only lasted a couple of seconds" and that they "felt a single jolt, a bit like being in a car that has done an emergency stop".

The quake hit 10 miles west of L.A. at 11.39 pm local time on Friday, according to the US Geological Survey.
It occurred at a depth of nearly 11 miles, and lasted for 30 seconds. It was reported to be one of the biggest earthquakes to hit the L.A. area in years.
There have been no reports of injuries or damage to property, but authorities warned locals to prepare for aftershocks.
The Los Angeles Fire Department posted a tweet shortly after the quake, which read: 'If Inside When Shaking Starts: DROP, COVER, HOLD ON! Protect Your Head & Neck While Taking Cover Under Sturdy Furniture or Near a Sturdy Interior Wall, Away From Windows and Doorways Until Shaking Stops.
The epicenter is over 4,000 miles away from the state of Florida and poses no tsunami threat to the U.S. mainland.

The EMSC said the quake hit at a depth of 320km - nearly 200 miles - at around 03:41 UTC, or 04:41 UK time.
There are no reports of damage or injuries at the time of writing.
However, there have been at least 14 reports of people feeling the quake, according to EMSC.
Accounts vary widely, with some reporting stronger feelings of shaking than others, with the duration of the quake also reported differently amongst people.

The latest Leighton Buzzard quake is thought to have been an aftershock from the magnitude 3.5 quake that was felt on September 8
The latest Leighton Buzzard quake is thought to have been an aftershock from the magnitude 3.5 quake that was felt on September 8
The tremor in Bedfordshire, which hit at 11.20pm on Sunday night, was measured by the BGS at magnitude 2.1.
It is thought to have been an aftershock from the magnitude 3.5 quake that was felt on September 8.
A BGS spokesman said: 'The most recent event was over 100 times smaller than the event on September 8 in the same area.
'The occurrence of smaller events from other previous UK earthquakes is not unknown.
'The small event that occurred in Bedfordshire last night could have occurred because all the stress in the rocks was not relieved by the event on September 8 in the same area or it caused a slight change to the stress regime in that location.
'There is constant ongoing research in the academic world on the issue of aftershock occurrence.'
