These follow a series of small earthquakes in the same area at the beginning of the week.

NORTH LAKE TAHOE, Calif. - The University of Nevada Seismological Lab is reporting a 2.9 earthquake on Friday, October 25 at 6:54 a.m. Centered six miles NNE of Tahoe City, the earthquake was 9km deep.

In the area of Bordertown, northwest of Reno, there has been a series of 38 small earthquakes since Thursday, October 24 at 3:00 p.m., all under a magnitude of 1.

On October 23 Incline Village experienced another small quake, one measuring 1.0 and another small one in between Incline Village and Tahoe City just prior to the 2.9.

SOUTH LAKE TAHOE, Calif. - What would happen if fire-fighting agencies could stop a wildfire before it gains momentum and wipes out homes, communities and/or forests? That is being answered with well over 100 fire cameras now in place across the west, all because of foresight of Dr. Graham Kent, the Director of the Nevada Seismological Laboratory at the University of Nevada Reno (UNR).

SOUTH LAKE TAHOE, Calif. - Did you feel it? A 4.1 earthquake centered at Dollar Point on the North Shore of Lake Tahoe occurred at 3:09 p.m. on Thursday, August 30, 2018. This follows two from earlier in the day near Mt. Rose, a 2.0 and 1.0.

It was at a depth of 7.82 km according to the Nevada Seismological Department at the University of Nevada Reno.

People near Cameron Park are reporting they felt the earthquake as well.

This is a developing story.

U.S. Senator Dean Heller (R-NV) will host the 22nd Annual Lake Tahoe Summit at Sand Harbor State Park in Incline Village, Nevada on Tuesday, August 7th, 2018 at 10:00 a.m. Beach and park operations will be closed until 1:00 p.m. that day.

Lawmakers from Nevada and California will meet on the shores of Lake Tahoe to discuss how to protect a national treasure as it faces continued threats to water clarity, invasive species, wildfire and drought.

There have been several earthquakes north of Lake Tahoe today, starting with one that measured 3.1 at 12:32 a.m. Wednesday.

According to the Nevada State Seismology Lab at the University of Nevada Reno, there have been 12 more tremblers as of 1:20 p.m. All are between five miles north of Mt. Rose and Interstate 80.

The Sierra Nevada and Western Nevada experience several earthquakes annually, and in recent years those numbers have been over 22,000 each year, with most of them under 1.0. So far in 2018 there have been over 6,000 measurable events.

The have been eight tremblers in the Mammoth Lakes / Mono Lake area in the last 12 hours, the smallest measured 1.2 on the Richter Scale, the largest at 3.7, according to the Nevada Seismological Laboratory on the UNR campus.

This area is a very active earthquake area, with swarms not unusual as it is one of the most seismically active volcanic regions in California. In 2014, there were more than 600 registered earthquakes in Mammoth in 36 hours.

9:30 a.m. update: The area continues to see several earthquakes in this current swarm that started at 2:02 a.m. with a 4.0 earthquake according to the UNR Seismological Lab in Reno. Magnitude numbers have been updated and listed below.

A series of earthquakes hit north of Donner Lake early Tuesday morning, starting at 2:02 a.m. with a 4.0 quake and a session of following 14 other tremblers over 1.0 magnitude by 5:43 a.m.

All came from an area 10.5 to 11.8 miles North/Northwest of Donner Lake, near Independence Lake.

The time and magnitude as of 8:20 a.m. Tuesday:

In the last 12 hours there have been several tumblers according to the Nevada Seismological Laboratory at the University of Nevada, Reno. The largest of the 24 recorded on their equipment was a 3.9 earthquake at 3:45 p.m. Tuesday, 12.4 miles southeast of Gardnerville, Nevada.

It was followed by a 2.2 earthquake at 3:51 p.m.

Earthquakes are not uncommon through the Sierra and Northern Nevada.

South Lake Tahoe resident, and Tahoe Prosperity Center DEO Heidi Hill Drum was awarded Citizen of the Year by the North Lake Tahoe Resort Association, Chamber, Convention and Visitors Bureau.

Hill was given the honor during the 63rd annual Community Awards Banquet on April 6.

“I was very surprised and I am grateful to be recognized, but I am just the messenger," Heidi noted at the ceremony accepting the award. "Our dedicated Board of Directors and staff are just as deserving of the honor recognizing the importance of our work in the region.”

There was a small earthquake 10.56 miles WSW of South Lake Tahoe near Job's Peak at 5:55 p.m. Friday, January 6. It was just 1.5 in magnitude and comes on the heels of a large swarm of earthquakes hitting the Hawthorne, Nevada area since December 28, 2016.

According to the Nevada Seismological Laboratory, the earthquake was at a depth of 19.57 km.

1:35 a.m. update 12/28/16: There are widespread reports of those feeling the series of earthquakes and aftershocks this morning, from Lodi and Sacramento, to Reno and Lake Tahoe, and beyond. The have been 11 seismological events in the Hawthorne and Bridgeport area, and two in Tonopah since midnight, ranging from 1.9 to 5.7 in magnitude.

The focus of the 20th Anniversary of the Tahoe Summit is on the environment. And there is much to celebrate as lake clarity has improved; collaboration among agencies is strong and numerous restoration projects have been completed. But 20-20 hindsight also means that if only we had thought more about the impacts that focusing solely on the environment would have on our economy and community, we could have accomplished much more. Now, twenty years later, we find ourselves trying to play “catch up” on these other two areas.

Nine years after the devastating Angora Fire in South Lake Tahoe, the AlertTahoe system of cameras around the Lake Tahoe basin is helping to prevent another such disaster.

June 6, 2016: The Sagehen Fire, north of Truckee, broke out and was quickly extinguished by the USFS, Northstar and Truckee Fire Departments.

June 9, 2016: The Truckee Meadows Fire Department quickly put out the Patrick Fire off Interstate 80, near Reno.

The Nevada Seismological Laboratory at the University of Nevada Reno reports a series of small aftershocks after a 4.1 earthquake at 3:00 a.m. at Walker Lake, 12 miles northwest of the town of Hawthorne. It was located 6.76 miles under the surface.

This one followed a series of over 100 small earthquakes that surrounded a 4.3 last week and a 3.1 quake on Monday morning.

Since the early morning quake Tuesday there have been seven smaller ones, the largest of which measured 2.8 at the UNR lab.

Residents of the Reno area have reported feeling several earthquakes Tuesday night from South Reno to Northwest Reno. The Nevada Seismological Laboratory is reporting 11 earthquakes, most with an epicenter about 3.5 miles north of Galena High School and five with a magnitude above or equal to 3.0.

The largest earthquake has been upgraded to a 4.4, an increase from the original 3.4 according to the U.S. Geological Survey (USGS) as of 11:30 p.m. Tuesday. Magnitudes and exact locations may be changed once analysis is completed.

Courtney Brailo from the University of Nevada Reno Seismological Lab to discuss faulting and geologic history of the Lake Tahoe region using newly acquired LiDAR imagery at the UC Davis Tahoe Environmental Research Center (TERC) on September 17.

A $5 donation is suggested for this event. Doors open at 5:30 p.m.

The program will begin at 6 p.m. with refreshments and no-host bar from 5:30 - 6 p.m. at 291 Country Club Drive in Incline Village (between Tahoe Boulevard/SR 28 and Lakeshore Blvd.) on the campus of Sierra Nevada College.

1980 South Tahoe High graduate Dr. Graham Kent from the UNR Seismological Laboratory will give a presentation on ALERT Tahoe in Incline Village on Thursday, January 8.

ALERT Tahoe is a new, one-of-a-kind, fire camera and multi-hazard tracking system that includes smoke investigation, prescribed fire oversight, wildfire tracking, Earthquake Early Warning, and monitoring of extreme weather events. A prototype of the fire camera system is functioning, scoring early successes during the summer of 2014.

Dr. Kent will present on the existing and planned camera system.

From Tahoe’s mountaintops to the lake’s sandy bottom, scientists from the University of Nevada, Reno continue to study and find solutions to the breadth of issues that face the entire Lake Tahoe Basin. Their research is making a tangible contribution to the decisions, policies and practices that guide the basin’s environmental health.

When the Sutter Mill’s meteorite streaked across the Nevada sky in April, it made a loud boom and shook homes throughout the region. Ken Smith, associate director for the Nevada Seismological Laboratory at the University of Nevada, Reno heard it and felt it that Sunday morning. His scientific curiosity drew him right to the lab’s earthquake monitoring network to see what registered on the more than 150 reporting stations. He found an astonishing series of registrations.

The erratic year-to-year swings in precipitation totals in the Lake Tahoe, Carson City and Reno areas conjures up the word “drought” every couple of years, and this year is no exception. The Nevada State Climate Office at the University of Nevada, Reno, in conjunction with the Nevada Drought Response Committee, announced Thursday a Stage 1 drought (moderate) for six counties and a Stage 2 drought (severe) for 11 counties.
Lake Tahoe and the Sierra Nevada are no strangers to drought, the most famous being the Medieval megadrought lasting from 800 to 1250 A.D. when annual precipitation was less than 60 percent of normal. The Reno-Tahoe region is now about 65 percent of annual normal precipitation for the year, which doesn’t seem like much, but imagine if this were the “norm” each and every year for the next 200 years.
