Seismic Event – High Magnitude Earthquake
Around the globe, where significant utility infrastructure is located in or near major fault zones, earthquakes risk causing substantial physical disruption, with associated long-duration power outages. For example, the New Madrid Seismic Zone in the southern and midwestern US spans large areas in 7 states: Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee, and Mississippi. According to the US Department of Energy, a recurrence of the 1812, 7.7 (richter scale) earthquake on that fault could damage or destroy electric substations, transmission lines, and generating stations on a subcontinental scale, as well as natural gas pipelines supplying generators in many regions of the US power grid. Geologists advise that quakes of > 7.0 magnitude have occurred periodically on this fault zone. Such an event occurring today could cause a vast multi-region power outage directly affecting 100-150 million people across the Northeast, Southeast and Midwest United States. Given the interdependent disruptive effects of such an outage on critical national and international supply chains and all other sectors (e.g., food, water, pharmaceutical, finance, shipping, transportation), such an event could create an unprecedented civilization-scale complex catastrophe.
This represents a particularly complex threat to the US and to the entire world, on a scale that could threaten societal continuity across all nations. While significant resilience work has begun, headed by the Central United States Earthquake Consortium (CUSEC)1, the success of CUSEC’s efforts will depend on broad availability of Black Sky-compatible tools and capabilities essential for multi-corporate communication, situational awareness and emergency power continuity, and on reversing an alarming national decline in blackstart assets. At present, such tools and capabilities are not widely deployed in the United States.
For more information on Black Sky-compatible tools and capabilities, and on the development of “EPRO Handbook V: Blackstart Restoration for a Greener Grid,” a new blackstart enhancement research initiative contact us.
1 CUSEC is a partnership of the federal government and the seven states most affected by an earthquake in the New Madrid Seismic Zone. Those states are Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri, and Tennessee.

EMP Risk Assessment for Critical Infrastructure
Electromagnetic Pulse (EMP) events pose a significant threat to critical infrastructure systems worldwide. These high-intensity bursts of electromagnetic energy can be caused by natural phenomena like solar storms or human-made events, such as a nuclear EMP attack. Given the growing reliance on interconnected and digitalized systems, the need for comprehensive EMP risk assessment has never […]
Is Emergency Supply Hoarding Wrong?
Written by Ranger Dorn, Exercise Program Director, EIS Council. We’ve all seen it—the rush of people emptying store shelves before or right after a disaster strikes. The media often portrays these scenes negatively, and in some ways, they are right. However, the problem isn’t with gathering emergency supplies; it’s with the timing, when people do […]
Extreme Pandemics
COVID-19's historic and continuing, tragic cost in lives, health and societal well-being represents the first near-Black Sky-class pandemic event in modern times. The unprecedented, global disruption highlighted the potential for a more severe pandemic that could become a global complex catastrophe, with large scale infrastructure disruption...
