US earthquake safety relies on federal employees' expertise

Earthquakes and the damage they cause are apolitical. Collectively, we either prepare for future earthquakes or the population eventually pays the price. The earthquakes that struck Myanmar on March 28, 2025, collapsing buildings and causing more than 3,000 deaths, were a sobering reminder of the risks and the need for preparation.

In the U.S., this preparation hinges in large part on the expertise of scientists and engineers in federal agencies who develop earthquake hazard models and contribute to the creation of building codes designed to ensure homes, high-rises and other structures won't collapse when the ground shakes.

Local communities and states decide whether to adopt building code documents. But those documents and other essential resources are developed through programs supported by federal agencies working in partnership with practicing engineers and earthquake experts at universities.

This essential federal role is illustrated by two programs that we work closely with as an earthquake engineer and a disaster management expert whose work focuses on seismic risk.

Improving Building Codes

First, seismologists and earthquake engineers at the U.S. Geological Survey, or USGS, produce the National Seismic Hazard Model. These maps, based on research into earthquake sources such as faults and how seismic waves move through the earth's crust, are used to determine the forces that structures in each community should be designed to resist.

A steering committee of earthquake experts from the private sector and universities works with USGS to ensure that the National Seismic Hazard Model implements the best available science.

Second, the Federal Emergency Management Agency, FEMA, supports the process for periodically updating building codes. That includes supporting the work of the National Institute of Building Sciences' Provisions Update Committee, which recommends building code revisions based on investigations of earthquake damage.
