Navajo County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Navajo County: 0.
2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

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 AZ GS (950).

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. Jun 1, 2011Wildfire, White Mountains$58.0 million
   National Weather Service narrative

   The Wallow Fire entered Apache County around 200 PM on June first. The fire burned a total of 313,103 acres in Apache County. The fire did not spread after June 30th (it was contained). The fire was declared out (controlled) on July 13th. It cost an estimated 58 million dollars to fight the fire in Apache County alone.

2. Apr 28, 2018Wildfire, Eastern Mogollon Rim$50.0 million
   National Weather Service narrative

   The Tinder Fire was first seen by Moqui Tower lookout on April 27 11:43 AM. Investigators determined that the fire originated in the East Clear Creek drainage approximately 1 mile downstream from Forest Road 95. Forest Road 95 runs north-south and is located approximately 1.5 miles east of C.C. Cragin (Blue Ridge) Reservoir. The cause of the fire was an abandoned illegal campfire. The fire burned 16,309 acres, 33 primary residences, and 54 minor structures.

3. Jul 21, 2019Wildfire, Black Mesa Area$9.0 million
   National Weather Service narrative

   The Museum Fire started about 4 miles north of Flagstaff on Sunday July 21 at around 1115 AM. The fire grew to 1,962 acres in the Dry Lake Hills area. The burn severity was 12% High, 28% moderate, 48%, and 12% very low. Much of this area drains into the Spruce Wash which runs into several communities of Flagstaff. An initial estimate of $9 million was spent on fire suppression. Extensive flood protection measures (200,000 sand bags and many jersey barriers) have been put in place below the fire scar.

6. Dec 28, 2004Flood, Eastern Mogollon Rim$66,000
   National Weather Service narrative

   A strong Pacific storm system moved across Arizona December 28th and 29th with heavy rainfall. The governor of Arizona declared a state of emergency for Coconino and Yavapai Counties which provided $200,000 aid for relief efforts. The heavy rain and melting snow resulted in excessive runoff in many areas from Williams to Flagstaff to Winslow and south to Prescott and Black Canyon City. High water, mudslides, and rock slides resulted in numerous road closures and evacuations in the area. Many creeks experienced significant rises. Oak Creak near Sedona exceeded bank full for a few hours when it rose 14 feet on the 29th and the Little Colorado River reached bankfull near Winslow.…

7. Apr 5, 2010Dust Storm, Little Colorado River Valley In Coconino County$60,000
