Which part of the United States is at most risk for earthquakes?
The 16 states with the highest earthquake hazard from natural earthquakes are Alaska, Arkansas, California, Hawaii, Idaho, Illinois, Kentucky, Missouri, Montana, Nevada, Oregon, South Carolina, Tennessee, Utah, Washington, and Wyoming.
What parts of the U.S. are affected by earthquakes?
When one considers very strong ground shaking levels, the 10 states with the highest populations exposed (in descending order) are California, Washington, Utah, Tennessee, Oregon, South Carolina, Nevada, Arkansas, Missouri and Illinois.

What two areas of the US have the highest risk of earthquakes with a magnitude ≥ 9?
Known as the Cascadia Subduction Zone, this 680-mile long stretch of colliding land mass 50 miles offshore of Oregon, Washington state and southern British Columbia is capable of generating magnitude 9 earthquakes 30 times more powerful than the worst the San Andreas can dish out.
What areas in California are at the highest risk for earthquakes?
Greater Bay Area The greater San Francisco Bay Area has a high likelihood of future damaging earthquakes as it straddles the San Andreas fault system—the major geologic boundary between the North American and Pacific tectonic plates.
What do national hazard maps show about earthquakes?
The National Hazard Maps show the distribution of earthquake shaking levels that have a certain probability of occurring in the United States.
Are there earthquake hazards in the United States?
The chances of experiencing shaking from an earthquake and/or having property damage is dependent on many different factors. The National Hazard Maps use all available data to estimate the chances of shaking (of different strengths and frequencies) across the U.S., but a probability is the best anyone can do.
Earthquake ground shaking varies from place to place and the hazard mapping in this project will show this variability. The mapped hazard refers to an estimate of the probability of exceeding a certain amount of ground shaking, or ground motion, in 50 years.
How is the probability of an earthquake determined?
The National Seismic Hazards Mapping project provides an online Web tool for determining the probability of a large earthquake within 50 kilometers (~31 miles) of a specific location in the United States over a certain time period. The calculation is based on the latest available information from seismic hazard data. However, asking if it’s safe…
