A group, led by the U.S. Geological Survey, presented the most recent version of the National Seismic Hazard Model, that includes several notable discoveries about earthquakes in the United States. The group highlighted that nearly 75% of the country could potentially encounter severe ground shaking and damage from earthquakes.
The model was formulated incorporating the newest seismic research, historical geological data, and cutting-edge data-collection methods. According to the USGS, studying faults and past seismic events enables scientists to improve their knowledge on the probability and potential intensity of future earthquakes. In any case, earthquake prediction remains impossible.
Furthermore, Mark Petersen, a geophysicist at the USGS and the principal author of the study, described it as an extensive, multi-year collaborative endeavor involving federal, state, and local governments, as well as the private sector. He outlined that the updated seismic hazard model represents a significant milestone for public safety improvement.
Using the National Seismic Hazard Model, a color-coded map that encompasses all 50 states has been generated for the first time. Highlighted regions, notably shaded in vivid red and burgundy hues, include areas such as California, segments of the Pacific Northwest, the mid-South, Alaska, and Hawaii. Scientists leading the project express concern that these states are at high risk.
In all, researchers have identified that 37 states have encountered earthquakes exceeding a magnitude of 5 within the previous two centuries. The USGS emphasized that this revised version of the National Seismic Hazard Model will provide pivotal insights for architects and engineers regarding the design and construction of buildings and other infrastructure in the United States.
