Regions in the United States Susceptible to Catastrophic Solar Storm Impacts Identified
Waking up to a world without electricity? It's not the premise of a sci-fi novel, but a very real possibility if a massive solar storm hit Earth. And for the first time ever, scientists have mapped out the regions in the U.S. that would be most impacted by such an event.
A geomagnetic storm, triggered by highly charged solar particles slamming into Earth's magnetic field, could wreak havoc on power grids and other infrastructure on an unprecedented scale. The financial damage? Up to a staggering $2.6 trillion. And it could take months, if not years, to fully recover.
But thanks to groundbreaking research by the U.S. Geological Survey (USGS), we now know which parts of the country are most at risk. This map isn't just a research project; it's a potential lifesaver, offering a rare chance to prepare for a catastrophe before it happens.
Why are some places more at risk than others? The biggest factors at play are latitude and geology. High-latitude areas, closer to Earth's magnetic poles, are natural targets for solar storm activity, as they receive a greater influx of charged particles. Subsurface rock composition also plays a role, with some rock types being more conductive, making power grids in those areas more susceptible to damage.
Geophysicist Jeffrey Love from the USGS explains, "Power grids are grounded, so they can pick up electric fields generated deep inside the Earth. But that geoelectric activity depends on the geology, and that's different from one region to the next." Using data from INTERMAGNET, a global network monitoring Earth's magnetic field, and the U.S. National Science Foundation's EarthScope program, researchers have pinpointed the areas at highest risk.
The findings are alarming. Among the most vulnerable states are Minnesota and Wisconsin, with "red zones" indicating where geoelectric hazards are at their peak. The northeastern U.S. is also a major concern due to its combination of dense population centers and extensive power infrastructure. However, here's the shocking part: more than half the U.S. hasn't even been charted yet. That's right, scientists are still missing crucial data from many parts of the country, including the northeast. The only thing standing in their way? Funding.
Despite the urgency, securing the necessary funding for this research has been an uphill battle. Researchers estimate that just $500,000 is needed to complete the survey, a fraction of what it would cost to recover from a full-blown geomagnetic storm. "Hello, that's where a lot of people live," said Love. "It's also where a lot of power grid infrastructure is located, and it's sitting on top of some complicated geology... Given the stakes, which are quite high, and the costs, which are quite low, it's worth it. $500,000 is about the price of a condo."
The last time Earth was hit by a geomagnetic storm of this magnitude was in 1859, known as the Carrington Event. It caused telegraph systems across the U.S. and Europe to fail, setting some on fire. But that was before our world became utterly dependent on electricity and digital networks. Today, the impact would be far more catastrophic. Many experts believe it's not a matter of if another major solar storm will hit—it's when. Some studies suggest that there is a 12% chance of a Carrington-level event occurring within the next decade. If a solar storm of that magnitude were to strike, the entire power grid could collapse, plunging cities into prolonged blackouts. Hospitals, emergency services, banks, and food supply chains would all be thrown into chaos. Without electricity, modern life as we know it would come to a screeching halt.
But there is hope. The USGS research isn't just about identifying vulnerabilities—it's about giving utilities a roadmap to strengthen their infrastructure before disaster strikes. The goal is to develop mitigation strategies, such as upgrading transformers to withstand geomagnetic-induced currents, developing fail-safe mechanisms, and building emergency backup systems. "The hope is to help power utilities find out where their networks have weaknesses, how their systems might respond, and how they could alleviate problems," said Love. "If we don't do it, we don't know what the risk is in the northeast."
In conclusion, the newly developed U.S. power grid vulnerability map is a wake-up call. Scientists now have the ability to identify the regions at the highest risk, but without adequate funding and swift action, this research will remain just that—research. Governments, power companies, and policymakers must act now to safeguard the grid before the next big solar storm arrives. Because when it does, the cost of inaction will be far greater than $500,000. The question isn't whether we can afford to invest in this research—it's whether we can afford not to.

Utilities and grid operators also often provide information on how they prepare for and respond to geomagnetic storms.
- The health-and-wellness impacts of a massive solar storm could be severe, as hospitals might lose power, throwing their services into chaos.
- Climate change and environmental science aren't typically linked to solar storms, but understanding geology is crucial for predicting the impact on power grids.
- Technology plays a significant role in monitoring Earth's magnetic field, like the INTERMAGNET global network and the U.S. National Science Foundation's EarthScope program.
- Fitness-and-exercise routines might be affected if gyms and healthcare facilities lose power during a solar storm, highlighting the importance of policy-and-legislation that ensures critical infrastructure remains operational.
- The threat of war-and-conflicts could escalate if countries lack the ability to communicate or coordinate responses during a prolonged blackout caused by a solar storm.
- Car-accidents could increase due to traffic light malfunctions during a solar storm, underscoring the need for emergency backup systems in infrastructure.
- General-news outlets and crime-and-justice agencies would struggle to function without electricity, making it difficult to maintain law and order during a protracted power outage. Accidents and fires might go unreported or unaddressed, leading to further chaos.
