At least two earthquakes with the strength of 6.0 and 4.8 magnitudes jolted Central California on Thursday afternoon. Merced Sun-Star reported that the tremors were felt at least 25 seconds apart. CBS Sacramento noted that the shaking of the earth happened around 3:50 in the afternoon.

2 Earthquakes Shakes California: Tremors Felt in Sacramento

The 6.0 magnitude earthquake that was felt in Central California was initially reported at 5.9, but was eventually upgraded by the United States Geological Survey. According to ABC 30, the USGS registered the tremor at around 3:49 in the afternoon on the east side of the Sierra Nevada Mountain range. Merced Sun-Star noted that the tremor centered on the Little Antelope Valley about four miles of Coleville and 150 miles east of Sacramento.

Earthquakes Shake Central CaliforniaThe National Weather Service in Sacramento described the tremors felt in the state to last for at least a minute. They also depicted the movement as light building motion or shaking.

In a briefing held on Thursday, the USGS said that the 6.0 magnitude earthquake was particularly common in the area, as reported by CBS Sacramento. The agency added that there was a six percent chance that quake shaking was a foreshock of a larger earthquake.

Since the first earthquake, a swarm of aftershocks with magnitudes ranging from 2.9 and 4.2 was felt. ABC 30 underscored that the earthquake and its aftershock were shallow, adding that it originated from five miles underground.

"It's a region with known active faults," USGS researcher Austin Elliot said, according to a Merced Sun-Star report. Elliot added that the region where the earthquake took place, was a "classic place geologists go to study."

Despite the strength of the shaking, USGS noted that there was no great deal of damages reported. So far, the damages accounted for the earthquake were from the Coleville rockslide. The shakings were felt from the San Francisco Bay Area to the east of Carson City Nevada.

"We are working closely with the local officials to ensure they have the resources and support to rapidly respond to these earthquakes," the Governor's Office of Emergency Services said in a statement.

4.8 Earthquake in Farmington Reportedly 'Phantom'

Earlier reports revealed that another earthquake was reported to have a magnitude of 4.8 that happened 25 seconds apart from the bigger tremor. reported that the USGS removed the report of the weaker tremor that happened in San Joaquin County. USGS explained that the second weaker earthquake reported earlier was a phantom, that stemmed out from their automated reporting, The Sacramento Bee reported.

"The faster we release earthquake locations and magnitudes, the more likely it is that the information may be erroneous," USGS said in a statement. Elliott and other seismologists that the glitch was not uncommon because seismic waves cause reflection as they spread emphasizing that one of those reflections just happened to center in Farmington.

Jackie Caplan-Auerbach, a seismologist from Western Washington University also hopped in explaining the phantom quake that was reported to be felt alongside the magnitude 6.0 earthquake in California. Caplan-Auerbach noted that location algorithms can sometimes yield an incorrect location, adding that sometimes the algorithm reports that shaking occurred nearby although it was from a location farther away.
