The quakes stretched from San Francisco to Las Vegas and along the border with Mexico. The first quake, with a magnitude of 1.1, struck at 3.30am local time on December 31 in the Californian town of Brawley, with over 100 aftershocks reported afterwards throughout the early morning hours.
The area was struck by a magnitude 5.4 earthquake in 2012, although the strongest quake of this latest swarm was recorded as magnitude 3.9. Scientists have said a stronger quake is still a possibility in the coming days, however, according to KABC.
No injuries or serious damage has been reported at this stage.
The swarm comes only days after another series of 200 tremors rattled the California Nevada border on Wednesday, which followed an earthquake measuring 5.7 early in the morning, reported the LA Times.
Foreshocks have been registered before approximately half of all major earthquakes in California’s history however, due to its proximity to the highly active San Andreas fault, residents were not quite quaking in their boots given the relatively small magnitude of this particular swarm. One local even suggested making a game of it:
While another suggested the swarm was a parting blow from a long and controversial 2016.
The last major earthquake to hit California occurred in 1992 in Landers, 133 miles (214km) north of Brawley, hitting 7.3 on the Richter scale. 3 people were killed and more than 400 people were injured.
