A map highlights earthquake hazard areas across the United States using a color-coded scheme to indicate different levels of hazard.

Areas in the United States with greater than 1% probability of potentially damaging ground shaking in one year

Earthquake Hazard Areas (U.S.)

The lowest hazard areas are shaded in blue, covering parts of Texas, Florida, Iowa, North Dakota, and Wisconsin, as well as extreme northern regions of Alaska. Low hazard areas are shaded in purple, seen in regions such as parts of the eastern and middle United States, including Dallas, Chicago, and Washington D.C. Moderately low hazard areas are shaded in pink, found in central and northern Illinois, and spread across western parts including Oregon, Arizona, and New Mexico. Moderate hazard areas are shaded in orange, covering parts of the eastern and western regions, and most of Alaska. Moderately high hazard areas are shaded in yellow, covering regions such as the West Coast, including California, Oregon, and Washington, as well as Fairbanks in Alaska. High hazard areas are shaded in light brown, seen in parts of Anchorage and the western coastal regions. The highest hazard areas are shaded in dark brown, notably in regions like southern Alaska and parts of California, including the San Francisco and Los Angeles areas.

Global vulnerability to a 2-meter sea-level rise is shown with areas highlighted in blue and indicates regions at risk.

Areas vulnerable to a 2-meter rise in sea level

Sea-Level Rise Vulnerability (2 m)

Coastal regions across continents are marked, indicating potential flooding hazards. In North America, significant vulnerable areas include the eastern seaboard, the Gulf Coast, and parts of Alaska and Canada. Central America shows risk in Mexico and the Caribbean coastlines, while South America has vulnerable zones along the coasts of Colombia, Peru, Brazil, and Argentina. Europe displays extensive risk along the North Sea, Baltic Sea, and Mediterranean coasts, affecting countries like the United Kingdom, Spain, Italy, and Turkey. In Africa, vulnerable areas are mainly along the Mediterranean, West African coasts, and parts of the eastern coast near Kenya and Tanzania. Asia has numerous at-risk regions, including the coasts of Japan, China, India, Vietnam, and Indonesia. Australia’s vulnerable areas are primarily along the northern and eastern coasts, and New Zealand shows risk around its coastlines. Island nations like the Philippines, Papua New Guinea, and various Pacific islands are also prominently highlighted, indicating significant vulnerability to sea-level rise. This map underscores the global scale of potential impacts from rising sea levels, emphasizing the need for adaptive measures in coastal regions worldwide.
