This map indicates the approximate location of the epicenter of Saturday morning's quake near Greenville, Calif.

A shallow, magnitude 3.7 earthquake was reported Saturday morning five miles from Greenville, Calif., in Plumas County in the Sierra Nevada, according to the U.S. Geological Survey. The temblor occurred at 11:43 a.m. PDT at a depth of 0 miles.

According to the USGS, the epicenter was 27 miles from Susanville, 36 miles from Magalia, 40 miles from Paradise and 97 miles from Carson City, Nev.

The quake came two days after a magnitude 5.7 temblor struck Plumas County, the largest earthquake in California .

In the past ten days, there have been 26 earthquakes magnitude 3.0 and greater centered nearby.

Proclamation of Emergency


If you have had any damage to your home, please complete the Plumas Earthquake Survey 2013 (PDF) and return it to Plumas County Office of Emergency Services as soon as possible. It is very important for people who have property damage or property loss to report it. OES will be keeping track of the total loss for the county so that it can be reported to the state.

y ground deformation we notice. A damaged home in West Almanor will be reported to USGS as a possible example. Also, if there are reports of new water sources or springs where there were none before, USGS would be interested in gathering this information as well. Below is information on liquefaction.


A process by which water-saturated sediment temporarily loses strength and acts as a fluid, like when you wiggle your toes in the wet sand near the water at the beach. This effect can be caused by earthquake shaking.

Quincy earthquake called unusual for its magnitude

A magnitude 4.5 earthquake in Quincy that awoke Grass Valley and Nevada City residents from sleep early Friday morning is a reminder of the uplift that is constantly shaping the Sierra Nevada.

The medium-sized earthquake ” the biggest to rock the area in more than a decade ” occurred at 4:19 a.m. about 4 miles from the town of Quincy, according to the U.S. Geological Service.

Shortly after a report of the quake was posted on The Union’s Web site, several locals reported feeling lurches, a twisting motion and hearing a slow rumbling that lasted 10 to 30 seconds.

“It sounded horrible and horrific, and it woke everybody up,” said a Plumas County sheriff’s dispatch. Quincy has a population of 2,500 people.

No damage was reported in Quincy, Grass Valley or Nevada City.

More than 250 people from this area, as well as Chico, Susanville, Truckee and Reno, also reported feeling the quake, according to the USGS Web site. They reported the shaking as “light” to “moderate.”

Small earthquakes are not uncommon in the Sierra Nevada range, especially in a band of frequent seismic activity between Lake Tahoe and Mount Lassen.

But one with a magnitude of 4.5 is unusual.

“For the most part, earthquakes are common. It’s a magnitude issue. You don’t get a lot of large earthquakes” such as in the Bay Area or Southern California, said Rick

Wilson, a geologist with the California Geological Survey.

The Quincy earthquake could be an indicator of bigger earthquakes to come.

“There is potential for larger earthquakes,” Wilson said. “It could be relieving stress. It could be building up stress.”

An earthquake of similar magnitude was recorded in 1997 near Quincy, and in 1888, a 5.5-magnitude quake was felt by area residents.

In 2004, a cluster of earthquakes rattled the Mammoth Lakes area. In March 1872, 27 people died at Lone Pine when an earthquake destroyed 59 adobe houses, according to the USGS.

Beneath Lake Tahoe, a group of researchers from the Scripps Institution of Oceanography are studying whether a large, magnitude-7 earthquake could produce tsunami waves 3 to 10 meters high.

“It’s part of the mountain-building process for the Sierra Nevada,” Wilson said.

The eastern side of the mountain range is “shearing” and “being torn apart,” he added.

“It’s a reaction of the rest of the mountains moving,” Wilson said.

$1M Damage estimate from Plumas County Earthquake

QUINCY (AP) – Officials in a part of rural northeastern California that was shaken by a magnitude-5.7 earthquake last week are estimating that the temblor caused more than $1 million in damage.

Plumas County Office of Emergency Services Director Jerry Sipe said Tuesday that more than 50 homes in the Lake Almanor basin were damaged during the quake on Thursday night. The basin occupies a rugged region where the Sierra and Cascade mountains meet.

Sipe says broken and toppled chimneys were the most common type of damage, but that the quake also broke decks, porches and windows. Some homes suffered flooding and water damage, and one was lifted off its foundation.

The earthquake also ruptured a tank that supplies residential drinking water, but an advisory instructing customers to boil their drinking water was lifted over the weekend.

Update:  More small quakes have been reported as of Monday, May 24, with the United States Geological Survey (USGS) announcing a total of 18 earthquakes/micro-quakes between Lake Davis and Portola in the last few days. One Portola resident reported feeling two more earthquakes this morning, Monday.

She described the first on at approximately 8:30 a.m. as a “jolt” and another just before 10:00 a.m. that she said was more of a “rolling earthquake without any sharp hits”. The resident also stated she felt small tremors throughout the weekend. More information can be found here. 


The United States Geological Survey announced a 3.1-magnitude earthquake struck near Portola early Sunday morning, May 23, at 2:18 am local time, at a very shallow depth of 1.3 miles below the surface. Then another 2.8 quake registered at 10:20 a.m.

Individuals in the Portola area have reported feeling the events, but no damage has been reported at this time.
