Answer: The top 10 states that have the most exposure to earthquakes are California, Washington, Utah, Tennessee, Oregon, South Carolina, Nevada, Arkansas, Missouri, and Illinois.
Explanation: For the western states, such as California, Washington, and Oregon for example, the Pacific plate is strike-slipping against the North American plate, which causes earthquakes, mainly in California which is the biggest earthquake hazard. For the eastern states, such as South Carolina, lots of earthquake stress (epicenter) transmits inward from the boundaries of the North American plate, which makes it extremely vulnerable to earthquakes.
