Earthquakes are often associated with places like California or Alaska, but the reality is that seismic activity can happen much closer to home. In fact, several regions across the United States are vulnerable to earthquakes, with some areas more prone to significant shaking than others. These earthquake hotspots are often located near fault lines, where the Earth’s tectonic plates meet. While some places experience tremors frequently, others are at risk of more severe seismic events without frequent warning.
Here are ten earthquake hotspots in America that you might be living in. From the Pacific Coast to the heartland, these areas have been known to experience various degrees of seismic activity. Understanding the risks and being prepared can help reduce the impact of earthquakes when they strike. Whether you live in one of these areas or are planning to visit, knowing the risks and what to do before, during, and after an earthquake is crucial for your safety.
Los Angeles, California
Los Angeles sits near the infamous San Andreas Fault and several other fault lines, like the Puente Hills and Newport-Inglewood. The city experiences frequent small tremors, but experts agree a major event is likely in the future. Dense infrastructure, aging buildings, and high population density raise concerns about potential damage. Many residents live near faults without realizing it. Earthquake drills, retrofitting programs, and public warnings are standard, but gaps in preparedness remain. Because of its position on a tectonic boundary, Los Angeles faces ongoing seismic pressure that continues to build beneath the surface.
San Francisco Bay Area, California
The Bay Area is surrounded by a web of faults, with the San Andreas and Hayward faults posing the greatest concern. The 1906 earthquake devastated San Francisco, and scientists say the Hayward Fault is overdue for another major event. Cities like Oakland, Berkeley, and Fremont sit directly on or near active fault lines. Rapid urban growth and older structures increase the risk of damage. Ground shaking, liquefaction, and fire are among the expected hazards. Public awareness is high, but many areas still lack retrofitting. Earthquake preparedness remains a constant topic for both city planners and residents alike.
Anchorage, Alaska
Anchorage is located in one of the most seismically active zones in the world. Alaska experiences thousands of earthquakes each year, many centered near Anchorage due to the subduction of the Pacific Plate beneath the North American Plate. The 1964 Great Alaska Earthquake, a magnitude 9.2 event, caused major destruction and remains one of the strongest ever recorded. While modern building codes have improved resilience, the region still faces threats from tsunamis, landslides, and aftershocks. Remote locations and cold climate conditions can make recovery efforts more difficult, which is why emergency readiness is particularly emphasized in this part of the country.
Seattle, Washington
Seattle’s earthquake risk stems from both deep and shallow sources. The nearby Cascadia Subduction Zone could produce a massive magnitude 8–9 earthquake, while local faults like the Seattle Fault could also rupture. Either event could result in widespread destruction, from infrastructure collapse to landslides. Seattle’s hilly terrain and dense urban core make it especially vulnerable. Many buildings, bridges, and roads were not built with major earthquakes in mind. Scientists and emergency managers continue to push for better preparedness, early warning systems, and public awareness campaigns as the region waits for what many describe as an inevitable seismic event.
Salt Lake City, Utah
Salt Lake City sits directly on the Wasatch Fault, which stretches over 200 miles through Utah. The fault is capable of producing magnitude 7.0 earthquakes, and studies suggest it has ruptured every 1,300 years on average—yet the last major event occurred over 1,400 years ago. This means the region is overdue. The Salt Lake Valley’s soft sediment can amplify shaking, increasing the chance of damage. Many homes, schools, and hospitals are vulnerable due to age and construction type. Efforts to retrofit key structures are ongoing, but many buildings still lack reinforcement. Emergency planning and public education remain critical priorities.
Memphis, Tennessee

Memphis is located near the New Madrid Seismic Zone, a region responsible for a series of massive earthquakes in 1811–1812 that were felt as far away as the East Coast. Though often overlooked today, the area remains active and capable of producing significant quakes. Unlike the West Coast, infrastructure here is generally not built to handle strong shaking. Many homes, bridges, and pipelines lack reinforcement. Because the soil in the region can amplify seismic waves, even moderate earthquakes could cause severe damage. The combination of low preparedness and high risk makes this part of the country a growing concern.
Charleston, South Carolina
Charleston experienced one of the most damaging earthquakes in U.S. history in 1886, which caused widespread destruction and hundreds of deaths. Though it’s been quiet since, the seismic risk hasn’t gone away. The city sits on ancient fault lines that can still produce powerful quakes. Much of Charleston’s architecture is historic and not designed to withstand significant ground motion. Additionally, the area’s soft soil can increase shaking intensity. Despite the long gap since the last major event, geologists warn that future quakes are possible. Preparation is limited, and awareness tends to be low among residents and local policymakers.
Reno, Nevada
Reno lies near the Walker Lane fault system, a complex zone that absorbs tectonic strain from the western edge of the North American Plate. This area produces frequent small-to-moderate quakes, and scientists believe it could generate a larger one in the future. Rapid urban growth in Reno has outpaced seismic retrofitting efforts, and many buildings were not constructed with earthquakes in mind. Local geology—such as sediment basins—can also intensify ground shaking. While not as widely publicized as California’s risk, the region’s seismic activity is well-known among researchers and emergency managers working to close preparedness gaps.
New York City, New York
New York City isn’t known for earthquakes, but it sits on several small fault lines that can still cause measurable shaking. The last noticeable quake was in 2011, but older records show stronger events in the past. The city’s dense population, aging infrastructure, and limited public awareness make even a moderate quake a potential crisis. Skyscrapers and subways weren’t built with seismic threats in mind. Utility systems and roads could suffer if an unexpected event strikes. While the odds of a large quake are lower than on the West Coast, the impact could be substantial due to a lack of preparation.
St. Louis, Missouri
St. Louis is another major city at risk from the New Madrid Seismic Zone, which runs through southeastern Missouri and nearby states. Though most people don’t associate the Midwest with earthquakes, a large event here could affect millions. Much of St. Louis sits on deep soil deposits that can amplify seismic waves. Additionally, many structures—especially older homes and schools—lack earthquake-resistant features. Experts stress that preparedness in this region is low compared to the level of risk. Earthquake drills and retrofitting initiatives are not widespread, even though scientists warn that a significant event is possible in this century.
