Three Minor Earthquakes Rattle California on June 14, Including Late-Night Tremor Near Petrolia

Earthquakes shook several regions in California on Sunday, with one of the strongest ones occurring late on Sunday night.

A 3.3-magnitude earthquake shook near Petrolia in Humboldt County at 11:34 p.m. on June 14, according to the U.S. Geological Survey (USGS).

The epicenter was located 74 kilometers west of Petrolia, at a depth of 0.3 kilometers.

The epicenter sits close to other cities, including Ferndale, Fortuna, and Humboldt Hill.

Although higher in magnitude, the earthquake did not cause much noticeable shaking.

No responses were submitted about people feeling the shaking on the USGS’s ‘Did You Feel it?’ earthquake reporting system.

No damage or injuries were reported due to the tremor.

Other Incidents of Minor Earthquakes

California frequently experiences earthquakes, due to its location in one of the most seismically active zones in the world.

There were more incidents of earthquakes documented on Sunday.

A 3.3-magnitude earthquake was documented near Prattville in Plumas County at 11:24 a.m. on June 14, according to the USGS.

The epicenter was located 2 kilometeres east of Prattville, at a depth of 3.3 kilometers.

A total of 12 persons reported experiencing the shaking, according to the USGS’s ‘Did You Feel It?’ tool.

The shaking was felt at locations as far away as Glenbrook (173 kilometers from the epicenter) and other nearby communities, such as Westwood (7 kilometers) and Susanville (14 kilometers).

The USGS categorized the seismic event as Level III intensity, which indicates weak shaking and no 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.

Later on Sunday, another minor earthquake rattled near Calipatria in Imperial County.

A 3.2-magnitude tremor was recorded at 8:26 p.m., according to the USGS. The epicenter was located 10 kilometers northwest of Calipatria, at a depth of 6.5 kilometers.

A total of six persons reported feeling the earthquake using the USGS’s ‘Did You Feel It?’ reporting system.

The quake was felt at locations as far away as Mexicali in Mexico (58 kilometers from the epicenter) and other nearby places, such as Westmorland (18 kilometers) and Brawley (27 kilometers).

Although the magnitude was on the lower side, the USGS categorized the seismic event as Level IV intensity, which indicates light shaking and very light damage.

Earthquakes that occur at shallow depths usually result in more intense and noticeable shaking than quakes that occur deeper. The intensity of shaking from a seismic event tends to weaken as distance from the earthquake’s source increases.
