Wyoming Earthquakes – Current Map, Yellowstone & Teton Fault

No M1.5+ Wyoming earthquakes have been recorded in the past 24 hours.

In Wyoming, the earthquake pattern is shaped by a mix of national parks, mountain ranges, active faults, and the Yellowstone region. The busiest activity is usually in the west, but the reason that matters is not just geology. It is also where steep slopes, park roads, visitor areas, rural communities, and cross-border fault zones all come together.

This page tracks the latest Wyoming earthquake activity using USGS-based earthquake data. The map, recent earthquake list, statistics, and significant quake information update when the page loads or refreshes.

Why Does Western Wyoming See More Earthquake Activity?

If you are trying to understand Wyoming earthquakes, start with the west side of the state. The Wyoming State Geological Survey explains that most Wyoming earthquakes occur in western Wyoming and around Yellowstone, even though earthquakes have been recorded across the state.

That makes Wyoming different from a page like Utah, where the main concern is the Wasatch Front and a dense urban corridor. In Wyoming, the focus is more spread out. Yellowstone, Jackson Hole, the Teton Fault, Star Valley, Pinedale, Cody, and the western mountain corridors all matter, but for different reasons.

This does not mean eastern Wyoming has no earthquake risk. It means the map will usually make the most sense when you read it from west to east. If the markers cluster around Yellowstone or the Teton region, they are part of Wyoming’s main seismic story. If they appear farther east, the local context matters more.

Yellowstone Makes Wyoming Different

Yellowstone has its own earthquake page, but it also belongs here because most of Yellowstone National Park is in Wyoming. That means many Yellowstone earthquakes are also Wyoming earthquakes. The difference is that Yellowstone adds another layer, which is volcanic and hydrothermal activity.

The Yellowstone Volcano Observatory, which includes partners such as the University of Utah Seismograph Stations, tracks earthquakes, ground movement, hydrothermal activity, and volcanic signals across the region. That broader monitoring matters because a small Yellowstone swarm is not read the same way as a small quake in a quiet part of eastern Wyoming.

Still, it’s important not to overread the map. Most Yellowstone-region earthquakes are small, and a cluster of small quakes does not automatically mean an eruption is coming. If you want the volcano and swarm details, use the dedicated Yellowstone earthquakes page. This Wyoming page is more about how Yellowstone fits into the wider state picture.

Jackson Hole, Grand Teton, and the Teton Fault

South of Yellowstone, the next big Wyoming earthquake entity is the Teton Fault. This is the fault system that runs along the base of the Teton Range near Jackson Hole and Grand Teton National Park. It matters because it sits beside towns, park roads, trails, lakes, campgrounds, ski areas, and one of the busiest visitor regions in Wyoming.

A University of Wyoming / National Park Service Research Station report describes the Teton Fault as a major range-front normal fault along the east side of the Teton Range and part of the wider Intermountain Seismic Belt. The same research links the fault to the dramatic rise of the Teton Range and the development of Jackson Hole beside it. That Grand Teton earthquake hazard study is a better fit here than relying only on a generic national earthquake page.

This is where the earlier Yellowstone point connects back in. Western Wyoming is not one single earthquake zone. Yellowstone, Jackson Hole, the Teton Fault, and Star Valley are related by region, but they do not all mean the same thing. A Yellowstone swarm, a Teton Fault earthquake, and a small local quake near Star Valley need different context.

Why a Wyoming Earthquake May Also Feel Like a Montana or Idaho Seismic Event

Wyoming’s western earthquake zones sit close to state borders, so the labels can get messy. A quake near West Yellowstone may be listed in Montana, Wyoming, or the Yellowstone region depending on its exact location. A quake near Star Valley may matter to both Wyoming and Idaho. A Yellowstone swarm may show up as a Wyoming event while also belonging to a larger volcanic-region story.

This is why the related maps are useful, not just decorative links. If a marker appears near the northwest corner of Wyoming, compare it with the Yellowstone, Montana, and Idaho pages. If it appears farther south, the Utah earthquakes page may be more useful.

That cross-border pattern is part of what makes Wyoming different. State lines are useful for pages and maps, but earthquakes follow faults, valleys, and stress patterns instead.

Places to Watch on the Wyoming Earthquake Map

When you look at the map, these are the main Wyoming areas worth paying attention to.

• Yellowstone National Park: This is Wyoming’s busiest earthquake region. Small earthquakes and swarms are common, and the activity is best read alongside the dedicated Yellowstone earthquakes page.
• Jackson Hole and the Teton Range: This area matters because of the Teton Fault, Grand Teton National Park, local communities, ski areas, lakes, and major visitor routes.
• Star Valley and western Wyoming: Western Wyoming sits close to Idaho and Utah, so earthquakes here may be felt across state lines and can affect rural roads, valley floors, and mountain communities.
• Pinedale and the Wind River Range: This part of Wyoming includes mountain-front terrain, reservoirs, energy infrastructure, long travel routes, and smaller communities where access can matter after shaking.
• Cody and northwest Wyoming: Earthquakes around Cody and the Absaroka region may connect with Yellowstone-area tectonics, mountain faults, or regional stress around northwest Wyoming.
• Central and eastern Wyoming: These areas are usually quieter than western Wyoming, but historical earthquakes have still been recorded across the state. Local felt events can still matter, especially near towns, reservoirs, mines, or energy activity.

The 1959 Hebgen Lake Link to Wyoming

The 1959 Hebgen Lake earthquake happened in southwest Montana, but it is impossible to separate it from Wyoming’s earthquake story. It affected the Yellowstone region, produced aftershocks, and changed how scientists and the public understood earthquake hazards around the Montana-Wyoming-Idaho border.

The Wyoming State Geological Survey records Wyoming’s largest earthquake to date as an August 18, 1959 M6.3 earthquake in Yellowstone National Park, considered an aftershock of the Hebgen Lake earthquake. That detail is important because it shows how closely Wyoming’s largest recorded earthquake is tied to a border-region event.

This loops back to the point above: Wyoming earthquakes should not be read only by state boundaries. Some of the most important events for Wyoming are shared with Montana, Idaho, and Yellowstone.

Wyoming Earthquake Hazards

Wyoming’s earthquake hazards are not only about buildings falling down. In many parts of the state, the bigger concern may be what shaking does to slopes, roads, trails, thermal areas, bridges, and rural access routes.

• Ground shaking: Strong shaking can damage homes, schools, lodges, bridges, roads, utilities, older buildings, and visitor facilities.
• Rockfalls and landslides: Western Wyoming has steep slopes, canyon roads, park roads, road cuts, and mountain passes where shaking can create extra hazards.
• Thermal areas: In Yellowstone, shaking can happen near geysers, hot springs, and fragile thermal ground. Visitors should stay on marked boardwalks and trails.
• Road and access problems: Wyoming’s mountain routes can be vulnerable. Even a non-earthquake landslide on Teton Pass in 2024 showed how one damaged road can affect commuters, visitors, and emergency access in the Jackson area.
• Lake and river effects: Strong shaking can affect lake shores, riverbanks, dams, reservoirs, and steep valley walls.
• Aftershocks: A larger earthquake can be followed by aftershocks for days, weeks, or longer.

Key Wyoming and Nearby Earthquakes

• 1932 Gros Ventre / Rock Springs Region Earthquake (M6.7): Estimated as one of the largest historical shocks near the western border, this powerful tectonic earthquake triggered massive landslides and cracked masonry across regional towns.
  
• 1959 Hebgen Lake Earthquake (M7.3): Centered in southwest Montana, this massive event severely impacted the entire Yellowstone region, causing deadly landslides, altering geysers, and triggering intense cross-border seismic activity.
  
• 1959 Yellowstone National Park Aftershock (M6.3): Occurring on August 18 inside the Wyoming portion of the park, the WSGS officially recognizes this major Hebgen Lake aftershock as Wyoming’s largest instrumentally recorded earthquake to date.
  
• 1975 Norris Geyser Basin Earthquake (M6.1): This sizeable Yellowstone-area earthquake damaged local infrastructure and permanently altered nearby thermal plumbing, demonstrating why western Wyoming activity requires both fault and volcanic-region context.
  
• 1984 Laramie Mountains / Gillette Earthquake (M5.4): Striking eastern-central Wyoming, this deep-crust event cracked foundations, shattered windows, and was felt across five states, proving that seismic risk exists well outside the western mountains.
  
• 1994 Star Valley Earthquake (M5.9): Located right on the Idaho-Wyoming border, this modern tectonic event caused severe ground cracking and minor landslides, serving as a reminder of the active fault lines running down the state line.
  
• Teton Fault Prehistoric Earthquakes: Long-term paleoseismic trenching and LiDAR research by university and park scientists show evidence of massive prehistoric earthquakes (estimated M7.0–M7.5) that physically shaped the iconic Grand Teton mountain front.
  
• Ongoing Yellowstone Swarms: Small, highly frequent earthquake swarms continue to act as part of normal, everyday Yellowstone-region activity, helping scientists track subsurface fluids, hydrothermal networks, and active crustal stress.

Wyoming Earthquake Safety

Earthquake safety in Wyoming depends on where you are. A Yellowstone boardwalk, a Jackson hotel, a mountain road, a campground, and a rural highway all have different risks. The basic advice is still the same: protect yourself during shaking, then be careful around damaged buildings, slopes, roads, utilities, and thermal areas afterward.

• During shaking, Drop, Cover, and Hold On.
• If you are indoors, stay indoors until the shaking stops. Do not run outside while glass, signs, bricks, or power lines may be falling.
• If you are outside, move away from buildings, cliffs, rockfall areas, bridges, power lines, trees, and anything that could fall.
• If you are in a Yellowstone thermal area, stay on marked boardwalks and trails. Do not step onto open thermal ground after shaking.
• If you are driving, pull over when safe and avoid bridges, steep slopes, canyon walls, or damaged roads if possible.
• After shaking stops, check for injuries, gas smells, damaged utilities, unstable buildings, cracked roads, broken glass, rockfalls, and aftershocks.
• In mountain, park, or rural areas, keep extra water, food, fuel, blankets, and emergency supplies in your vehicle because detours can be long.

Who Tracks Wyoming Earthquakes?

Wyoming earthquakes are tracked through a mix of state, regional, and national monitoring. The best source depends on what you are looking at. For statewide earthquake history, the Wyoming State Geological Survey is the better starting point. For Yellowstone activity, the Yellowstone Volcano Observatory and University of Utah Seismograph Stations are more relevant. For national event pages and felt reports, USGS still has a role.

• Wyoming State Geological Survey: Provides Wyoming earthquake information, state hazard resources, and Wyoming-specific earthquake context.
• University of Wyoming / National Park Service Research Station: Includes research on Grand Teton National Park earthquake hazards and the Teton Fault.
• University of Utah Seismograph Stations: Helps monitor earthquakes in the Yellowstone region and the wider Intermountain West.
• Yellowstone Volcano Observatory: Monitors earthquake, volcanic, hydrothermal, and ground-deformation activity around Yellowstone.
• Wyoming Ready: Provides emergency preparedness guidance for Wyoming residents.
