Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Volcanoes within 100 miles

1. U.S. volcanoes within 100 miles, from the USGS Volcano Hazards Program. The threat category is the USGS 2018 National Volcanic Threat Assessment, which ranks volcanoes by how hazardous their past eruptions were and how many people and how much infrastructure lie near them. It is not a forecast of eruption.

Mapped landslides

Mapped by NASA (3), USGS Conterminous (1).

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

1. Oct 14, 2016Wildfire, Greater Reno/Carson City/Minden Area$30.0 million
   National Weather Service narrative

   A prescribed burn that was thought to be mopped up on October 13th flared up as high winds affected the Carson Range early on the 14th. The Little Valley Fire burned through 2,291 acres and destroyed 23 homes and 17 outbuildings. According to a Reno Gazette Journal investigation, the estimated value of 18 of the homes exceeded 26 million dollars with an independent fire consultant indicating that damages could exceed 80 million. The Little Valley RAWS measured a wind gust of 87 mph around 130 AM PDT on the 14th, close to the time of the wildfire start.

2. Nov 18, 2011Wildfire, Greater Reno/Carson City/Minden Area$8.0 million
   National Weather Service narrative

   High winds caused a tree to fall on a power line sparking a rapidly spreading wildfire in southwest Reno around 0030PST. The 2,000 acre Caughlin Fire fire spread, sometimes up to 30 mph, and caused the destruction of around 30 homes during the early morning of the 18th. Over 9,000 people were evacuated from the fire area early Friday before being allowed to return Saturday. One man died while evacuating his home, a firefighter suffered second-degree burns, and 16 others were admitted to area hospitals for smoke inhalation.

3. Dec 10, 2022Winter Storm, Greater Reno/Carson City/Minden Area$5.0 million
   National Weather Service narrative

   NWS Employee located 2.0 mi S of Spanish Springs relayed photos of wind damage at a CVS department store. A section of roofing material was torn off. The time of damage was estimated.

4. Jan 19, 2012Wildfire, Greater Reno/Carson City/Minden Area$4.5 million
   National Weather Service narrative

   Strong winds (up to 84 mph) and the improper disposal of fireplace ashes caused the rapid spread of a fire originating at the north end of Washoe Valley early in the afternoon on the 19th. Thousands of people were forced to evacuate from the swift-moving fire. Around 3100 acres were burned with 28 homes destroyed (7 damaged) and one fatality attributed to the fire. ||For information purposes only (not direct costs from wildfire), the tally of fire-fighting related costs were at least 1.5 million dollars.

There were an exceptionally high number of damage reports including power lines and trees downed (knocking out power to more than 10,000), fences damaged, and a semi-truck blown over on Interstate 80. In addition, winds caused more than 30 flight cancellations at the Reno-Tahoe International airport. Damages from this event are a rough estimate.

9. Feb 25, 2011Winter Storm, Greater Reno/Carson City/Minden Area$250,000
   National Weather Service narrative

   Widespread snowfall totals of 5 to 10 inches fell during this system, with 12 to 18 inches in areas west of Carson City and south and west of Reno (possibly enhanced by lake effect snow from Lake Tahoe). In addition to snow, winds gusted over 50 mph in the foothills and south of Reno from late morning into the afternoon on the 25th. Winds and snow in the Carson Valley caused 24 power poles to be broken or fall down onto both highway 395 and Muller Lane. In addition, several accidents caused at least two injuries in the Carson Valley. Finally, the snow was enough to cause Governor Sandoval to send home early non-essential state workers on the 25th.

10. Apr 27, 2010High Wind, Greater Reno/Carson City/Minden Area$250,000
    National Weather Service narrative
