A newly developed scientific mechanism by USGS scientists in Golden, Colorado, is set to revolutionize the assessment of global mineral supply risks due to seismic activity. This groundbreaking methodology focuses initially on copper and rhenium, two critical minerals, but lays the groundwork for evaluating numerous other mineral commodities worldwide.

The impetus for this advance stems from the need to mitigate disruptions in the supply chains of essential minerals that are vulnerable to earthquake-induced interruptions. The researchers' primary case studies on copper and rhenium were instrumental in outlining the framework, which is designed to be adaptable and applicable to a wide array of minerals.

Copper, a foundational element in electrical wiring, motors, and numerous electronic devices, and rhenium, crucial in aerospace engines and high-temperature turbine blades, serve as ideal candidates for this initial study due to their extensive industrial use and geographic concentration in earthquake-prone regions. The methodology involves a comprehensive analysis of the geological settings, mining infrastructure resilience, and historical seismic data to predict and quantify the potential supply risks accurately.

This innovative assessment tool integrates sophisticated risk modeling techniques with geological and seismological data to produce maps and scenarios that predict areas of high risk. These predictive models can inform policy-makers, mining companies, and international trade organizations about potential vulnerabilities and help them devise strategies to bolster mineral supply chain resilience.

In the broader context, this development is essential not just for industry stakeholders but for global economies that rely heavily on steady and reliable access to these critical minerals. The ability to foresee and mitigate disruptions due to seismic events can lead to more robust economic policies and disaster preparedness strategies.

Ultimately, the new USGS-developed methodology marks a significant step forward in the interdisciplinary field of mineral economics and disaster risk management. Its future applications could extend to a plethora of critical minerals, aiding in the fortification of supply chains worldwide against the unpredictable nature of earthquakes.
