Three earthquakes rocked the L.A. area in less than 10 minutes Saturday morning with magnitudes ranging from 3.1 to 2.1, according to the U.S. Geological Survey.

The 3.1 quake struck around 7:54 a.m. in Grananda Hills, and about 4 miles south of Santa Clarita and 7 miles west of San Fernando.

It was at a depth of about 4.5 miles.

The quake struck two minutes after a 2.7-magnitude earthquake and about eight minutes after a 2.1-magnitude quake hit the Granada Hills area, both at depths of less than a mile.

One KTLA viewer said the quakes woke him up, and several others reported feeling shaking in the Santa Clarita and San Fernando Valleys.

More than 400 people reported that they felt the 3.1 temblor to the U.S. Geological Survey’s “Did You Feel It?” map in the hour after it struck.

Following the quakes, the Los Angeles Fire Department was in “earthquake mode,” and had firefighters at all 106 fire stations “provide a complete and strategic survey of over 470-square miles in the greater Los Angeles area,” the department stated on Facebook.

The firefighters “rapidly leave quarters” and travel by ground, air and water to examine areas of major concern, including  transportation infrastructures such as freeway overpasses; large places of assembly, such as Dodger Stadium and universities; and apartment buildings, dams and power lines.

“Once this process is complete, all resources are rehoused and those firefighters immediately report back to head quarters of any significant damage or injuries,” LAFD stated on Facebook.

No significant damage or injuries were found during the LAFD’s survey, the department tweeted around 9:30 a.m.

Hundreds took to social media following the quakes:
