  • Resumen

  • USGS scientists in Golden, Colorado, have pioneered a groundbreaking methodology to quantify the global earthquake risk to mineral supplies. This new scientific mechanism, which initially focused on copper and rhenium, offers a comprehensive framework that can be adapted to evaluate the seismic risk to various other mineral commodities worldwide.

    The innovative approach addresses the increasing need to understand the vulnerabilities of critical mineral supplies that are vital for technological, industrial, and economic activities. By integrating geological data, seismic activity records, and mineral deposit locations, this methodology provides more accurate risk assessments.

    Earthquakes can severely disrupt mining operations, transportation networks, and supply chains. The USGS study identified specific areas where seismic activity has the potential to impact the availability of key minerals. This is crucial for industries and governments seeking to implement more effective resource management and disaster preparedness strategies.

    In particular, the research highlights that regions with significant copper and rhenium deposits, such as the Andes in South America and parts of China, are exposed to high seismic activity. These regions are essential for the global supply of these critical minerals. By applying this new risk quantification methodology, stakeholders can better anticipate and mitigate potential disruptions.

    The framework's adaptability for other minerals means industries dependent on rare earth elements, lithium, cobalt, and other valuable resources can benefit from more precise risk assessments. This advancement not only enhances the resilience of mineral supply chains but also informs investment decisions, policy-making, and international collaboration on resource security.

    Overall, the development of this seismic risk assessment tool marks a significant leap forward in safeguarding global mineral supplies against the uncertainties posed by earthquakes.
