GOLDEN, Colo. — USGS scientists have developed a pioneering methodology to quantify the global earthquake risk to mineral supplies, which may significantly impact various industries worldwide. This innovative framework, rooted in extensive research on copper and rhenium, not only elucidates the vulnerabilities of these critical minerals but also sets the stage for assessing numerous other mineral commodities globally.

Minerals are integral to modern technology and industrial processes, with copper being a fundamental element in electrical equipment and infrastructure, and rhenium playing a crucial role in high-temperature superalloys used in jet engines. Understanding how seismic activity could disrupt their supply chains is paramount for resource management and economic stability.

The new methodology, which involves a detailed analysis of geological and seismological data, enables scientists to pinpoint regions where the risk of supply interruption is high due to potential earthquakes. By mapping mineral deposits against fault lines and historic seismic activity, researchers can foresee which areas might face severe disruptions in the event of an earthquake.

This groundbreaking work emerges amidst growing concerns over the security of mineral supplies essential for everything from electronics to renewable energy technologies. As global demand for these minerals increases, particularly in the tech and green energy sectors, ensuring a stable and secure supply chain has never been more critical.

Future studies utilizing this methodology could extend to a variety of other minerals such as lithium, cobalt, and rare earth elements, which are fundamental to battery technologies and numerous advanced manufacturing processes. By anticipating and mitigating the impacts of seismic events on these supply chains, industries can enhance their resilience against natural disasters.

The USGS team's efforts mark a significant advancement in the intersection of earth science and resource management, offering a template that can be adapted to safeguard against a range of geological hazards. As such, this research is a vital step towards ensuring the sustainable and stable availability of crucial mineral resources in the face of an ever-dynamic planet.
