A groundbreaking new study by USGS scientists in Golden, Colo., has introduced a pioneering methodology to quantify the global risk of mineral supply disruptions due to seismic activity. This innovative approach, focused initially on copper and rhenium, offers a comprehensive framework that can be extended to assess the vulnerability of other essential mineral commodities worldwide.

Mineral commodities are crucial for various sectors, from electronics to renewable energy technologies, making the reliability and continuity of their supply chain paramount. This study aims to address growing concerns about how natural disasters, particularly earthquakes, can impact the availability and stability of these minerals.

To develop this risk assessment tool, the researchers conducted detailed evaluations of copper and rhenium supplies, considering factors such as mining locations, geological settings, and historical seismic activity data. The methodology incorporates advanced statistical models and geophysical analyses to predict the potential for supply chain disruptions in regions prone to earthquakes.

One key finding of the study is the identification of high-risk areas where the mineral supply chain is particularly vulnerable. By understanding these risks, stakeholders can implement strategic measures to mitigate potential disruptions, such as diversifying supply sources, enhancing infrastructure resilience, and adopting advanced monitoring technologies.

The implications of this study are far-reaching. As global demand for minerals continues to rise, particularly for those critical to green technologies and infrastructure, the ability to foresee and prepare for seismic-related supply disruptions becomes increasingly vital. This research not only aids in safeguarding the supply of copper and rhenium but also sets a precedent for future assessments of other minerals like lithium, cobalt, and rare earth elements, which are essential for the transition to a low-carbon economy.

The USGS's innovative approach signifies a significant advancement in the field of natural disaster risk assessment and mineral supply chain management. By providing a robust tool to evaluate and manage earthquake risks globally, this study contributes to the resilience and sustainability of critical mineral supplies essential for modern technological and economic development.
