A 3.6 magnitude earthquake shook the area near Cloverdale in Sonoma County on June 2.
The quake occurred at 9:44 a.m., 7 kilometers east-southeast of Cloverdale, according to the U.S. Geological Survey (USGS). The epicenter was located at a depth of 5.5 kilometers.
The shaking caused by the earthquake was felt by several people around the epicenter.
A total of 77 responses were submitted on the USGS’s ‘Did You Feel It?’ earthquake reporting system.
The USGS categorized the seismic event as Level IV intensity, which indicates light shaking and very light damage.
An earthquake’s intensity measures the shaking at each location, varying from place to place, whereas the magnitude denotes the size of a quake.
While multiple responses were submitted from places near the epicenter, locations as far away as San Francisco (124 kilometers from the epicenter), Concord (118 kilometers), and Mill Valley (105 kilometers) also experienced the tremor.
The earthquake was also felt at locations such as Santa Rosa, Novato, Vallejo, and Hopland, according to the USGS.
There were no reports of damage or injuries caused by the earthquake.
According to the USGS, the earthquake near Cloverdale occurred due to the Maacama Fault. The right-lateral strike-slip fault runs north of Santa Rosa and stretches to the Ukiah area.
The Maacama Fault is part of a larger network of faults and is a northern extension of the Hayward-Rodgers Creek fault system.
The 2007 Working Group for California Earthquake Probability estimated that the fault moves nearly 9 millimeters (around one-third of an inch) per year, while some sections of the fault gradually creep along at a slightly lower rate of about 7 (one-quarter of an inch) millimeters annually.
In Sonoma County north of Healdsburg, the Maacama Fault is mostly obscured by massive landslides where it runs east of Alexander Valley.
Scientists still know relatively little about the Maacama Fault’s seismic history or earthquake cycle. Therefore, it remains difficult to predict how often large earthquakes may occur in the future.
More Earthquakes in California
California frequently experiences earthquakes and is located in one of the most seismically active zones in the world.
There were more incidents of earthquakes documented on Tuesday.
A 2.9-magnitude earthquake rattled near San Jacinto in Riverside County at 9:16 p.m., according to the USGS. The epicenter was located 1 kilometer east-northeast of San Jacinto, at a depth of 13.6 kilometers.
A total of 78 responses were submitted on the USGS’s ‘Did You Feel It?’ tool. The USGS categorized the earthquake as Level IV intensity.
Earlier on Tuesday, a minor quake jolted near Huron in Fresno County.
A 2.6-magnitude earthquake was documented south-southeast of Huron at 6:48 a.m., according to the USGS. The epicenter was located at a depth of 7.9 kilometers.
There were no responses submitted using the ‘Did You Feel It?’ reporting tool. The USGS is yet to categorize the seismic event’s intensity.
