According to new maps released by the United States Geological Survey (USGS), nearly 75 percent of the US is at risk of experiencing earthquake damage over the next 100 years. The highest risk areas are California, Alaska, and the Big Island of Hawai'i, where the chance of damaging earthquake shaking is over 95 percent. The recent volcanic eruptions and seismic unrest on Hawai'i have increased its risk.

The USGS identified 500 additional fault lines that have the potential to produce damaging earthquakes. The new model incorporates seismic studies, historical geological data, and cutting-edge data collection technologies to provide the most detailed view ever of earthquake risks.

Notably, there have been "noteworthy changes" in the possibility of more damaging earthquakes along the central and northeastern Atlantic Coastal corridor, which could affect cities such as Washington DC, Philadelphia, New York, and Boston.

Earthquakes are caused by the movement of tectonic plates, which generate seismic waves that shake the ground when the built-up stress exceeds the strength of the rocks.

It is important for individuals and local governments in at-risk areas to consider this information when developing building codes and regulations. The US National Seismic Hazard Model offers a fresh assessment of earthquake risk in all 50 states and provides valuable insights to mitigate potential damage.
