Earthquakes

The quakes occurred along the Mendocino Fracture Zone at the junction between the San Andreas Fault and Cascadia Subduction Zone.

The small earthquakes were recorded by the USGS near Greenback and Sweetwater.

Local residents took to social media to report light shaking felt across the region, but no injuries or damage were reported.

The quake is the latest in a series of tremors that have struck the region in recent months.

Controversial research suggests these two huge tectonic regions are linked.

The tremor caused several buildings to collapse, burying people in the wreckage.

A report from England's Oil and Gas Authority has caused the government to call for a halt to fracking in the country on the basis of new earthquake fears.

"The Garlock Fault has been quiet for a long time. But there's geologic evidence that there have been large earthquakes on it," the lead author of a new study said.

Mild shakes were felt across parts of the Los Angeles area following another earthquake in California in the early hours this morning.

The newly identified natural phenomenon is the result of powerful storms transferring some of the vast amounts of energy that they produce into the Earth's crust.

"We often hear about the potential for large volcanic eruptions of the Yellowstone volcano. However, we rarely focus on the threat of large earthquakes in the region," researcher Jamie Farrell said.

NASA officials have said that the plane was flying as part of a mission to study the effects of fire smoke on air quality.

Earth is not the only place that experiences quakes.

In 1994, a huge 8.2 magnitude earthquake struck Bolivia. Scientists now use data from this quake to provide fascinating insights into Earth's interior.

The largest of the quakes measured 4.5 on the Richter scale.

It won't be like the movies—but a massive earthquake could still "cripple" the state of California.

Seismologists may have to completely change their models for the area based on latest findings.

The latest results could help to improve earthquake forecasting in the short term.

Condemning reformists who would like to see more gender-inclusive prayer spaces, ultra-Orthodox Israeli lawmaker said "they are not Jews."

In 1906, a powerful 7.9 magnitude earthquake caused the deaths of up to 3,000 people and destroyed more than 80 percent of the city of San Francisco.

Geologists have identified a new type of fault movement at San Andreas.

"It's so flat and white and boring in every direction but underneath you is a mountain range as big as the Pyrenees."

The total number of buildings destroyed during the latest series of eruptions has risen to more than 80.

The quakes came two hours apart and were likely caused by tectonic shifts in the Mariana Trench.

A decade after a massive earthquake killed almost 70,000 people, nature is reclaiming abandoned and shattered homes and schools.

Hawaii's National Guard has stepped in to help evacuations as authorities fear the lava is not slowing down yet.

If you live in Berkeley, Oakland, Fremont, Hayward or anywhere nearby, be prepared.

The tremors are "weird," but no one has been hurt.

Scientists will have just one instrument to measure seismic activity on Mars, compared to networks of hundreds of devices here on Earth.

A radio signal emitted from the source of an earthquake will reach a city seconds faster than the shakes.
