A recent 8.8-magnitude earthquake near Russia sparked Pacific-wide tsunami alerts, leading to an unexpected question from concerned citizens: Could Fargo, North Dakota, face a tsunami threat?
The National Weather Service in Grand Forks swiftly clarified these concerns by reassuring the public that, given North Dakota’s geographical characteristics, a tsunami is not a realistic scenario.
Let’s explore the science and common misconceptions behind this conversation.
Understanding Tsunamis and North Dakota’s Geography
A tsunami is a series of massive waves generated primarily by underwater earthquakes, volcanic eruptions, or landslides.
These events occur in oceans or seas, creating waves that move across vast distances with devastating power upon reaching coastal areas.
North Dakota, however, is a landlocked state located approximately 1,500 miles away from the nearest ocean coastline.
This makes the idea of an oceanic tsunami reaching Fargo scientifically implausible.
Flooding vs. Tsunamis: A Critical Distinction
While tsunamis are not a concern for North Dakota, flooding poses a real and serious threat.
For example, the 1997 Red River flood was a catastrophe that inflicted $3.5 billion in damages and led to mass evacuations.
This flood stemmed from precipitation, frozen ground, and river overflow—factors entirely unrelated to the seismic causes of tsunamis.
Could a “Lake Tsunami” Happen in North Dakota?
Some residents may wonder whether lake tsunamis—also known as meteotsunamis—could form in the state’s lakes.
Lake tsunamis are rare events triggered by earthquakes, landslides, or sudden atmospheric changes.
Yet, North Dakota’s seismic profile and geography make this possibility exceedingly unlikely.
The Role of Earthquakes in Lake Tsunamis
Earthquakes have the potential to cause lake tsunamis, but North Dakota lies in a region with very low seismic activity.
Minor tremors are infrequent, and even then, the North Dakota Geological Survey emphasizes that such events are unlikely to cause significant damage.
By comparison, a lake tsunami that occurred in British Columbia in 2020 resulted from a massive landslide that created a 328-foot wave across a glacial lake.
North Dakota’s landscape is relatively flat, lacking the steep topography or glacial lakes necessary for such scenarios.
Other Triggers: Landslides and Atmospheric Changes
In addition to earthquakes, landslides or sudden atmospheric shifts can produce meteotsunamis.
Yet, North Dakota’s lakes are relatively small and lack the geological conditions—such as steep cliffs or unstable sediment—that facilitate landslide-driven waves.
Even meteorological changes that might impact larger lakes are highly unlikely to cause waves of significant size or force in this region.
Mitigating Real Risks
Instead of worrying about tsunamis, North Dakotans should focus on preparing for the far more relevant threats posed by severe flooding and extreme weather.
Local authorities continue to invest in flood management systems and weather forecasting improvements.
Community education efforts are also underway to reduce the impact of these challenges.
