Kansas is not typically known for its earthquakes, but it does experience seismic activity. In the past 10 years, Kansas has seen 97 earthquakes with a magnitude of four or higher.
This averages to about 10 earthquakes per year, which means residents feel tremors roughly once every 38 days.
While most quakes in Kansas are minor, the state has experienced stronger ones. The strongest recent earthquake occurred on December 8, 2021, with a magnitude of 4.3. This quake struck 155 miles west-southwest of Kansas City.
Interestingly, Kansas officials note that the state is one of the least likely to suffer severe earthquake damage.
Seismic activity in Kansas can sometimes be linked to human activities, such as fracking. Despite this, the frequency of earthquakes still remains relatively low compared to other parts of the United States.

Historical Seismicity and Recent Trends
Kansas has experienced notable seismic activity over the years, influenced both by natural causes and human activities. This section will explore the patterns of seismic activity, compare Kansas to nearby regions, examine induced seismicity, and highlight significant historical earthquakes.
Patterns of Seismic Activity in Kansas
In Kansas, seismic activity has been recorded since the early days of the state. Historical records show that at least 31 earthquakes were felt in Kansas between 1867 and 1976.
The Kansas Geological Survey (KGS) has documented more than 100 earthquakes during studies from 1977 to 1989. Most of these earthquakes are small, often not felt by residents.
Recent monitoring shows fluctuating activity, with a notable decline after a peak in 2015.
Comparison with Nearby Regions
Kansas shares some seismic characteristics with neighboring states like Oklahoma. Although Kansas experiences fewer earthquakes than Oklahoma, the patterns can be similar.
For example, Oklahoma has seen a dramatic rise in earthquakes over the past decade, partly due to induced seismicity. While Oklahoma experiences more frequent and stronger seismic events, Kansas still faces significant activity, especially near the Oklahoma state line.
Impact of Induced Seismicity
Induced seismicity has significantly affected Kansas in recent years. This phenomenon, where human activities like wastewater injection cause earthquakes, has led to a noticeable increase in seismic events.
In Kansas, the Arbuckle formation has been a key area of concern. As fluid injection volumes decreased, seismicity also declined, suggesting a strong link between human activities and earthquake occurrences.
Significant Earthquakes in Kansas History
Kansas has not been immune to larger seismic events. The largest earthquake in recent years was a magnitude 4.9 event in 2014 in Sumner County near Milan. This quake caused minor damage to buildings and was linked to induced seismicity.
Historical newspaper accounts also document various felt earthquakes, spanning from minor tremors to significant quakes that left an impact on communities across the state.
Seismological Research and Tools
Seismological research in Kansas involves advanced tools and collaborative efforts to monitor and analyze earthquake activity effectively. These initiatives help assess seismic risk and improve earthquake response strategies.
Kansas Geological Survey Initiatives
The Kansas Geological Survey (KGS) plays a crucial role in monitoring seismic activity in the state. They operate a seismograph network that includes numerous stations, enhancing the detection and analysis of local earthquakes.
This network provides valuable earthquake data, aiding researchers in understanding seismic patterns. In 1979, KGS extended its efforts by adding more stations, further improving data accuracy.
Various projects have been launched to assess seismic hazards and develop better risk management strategies.
Advancements in Seismometer Technology
Seismometer technology has seen significant improvements, allowing for more precise and sensitive measurements.
Modern seismometers can detect even small earthquakes that might have gone unnoticed in the past.
These advancements help in mapping fault lines and predicting potential seismic events. The integration of digital technology enables real-time data transmission, which is crucial for timely earthquake response and analysis.
These tools are used by entities like the United States Geological Survey (USGS) and the Oklahoma Geological Survey for broader regional studies.
Contributions of Interactive Maps
Interactive maps are invaluable in tracking and visualizing earthquake data. The KGS uses digital maps to display real-time seismic activity, allowing the public and researchers to see where earthquakes are occurring in Kansas.
These maps provide a user-friendly interface to explore seismic data, including the epicenters and magnitudes of recent earthquakes.
They help identify trends and potential hazards, aiding in the preparation and response to seismic events. Users can access detailed information, such as historical earthquake records, through these interactive tools.
Collaborative Efforts for Monitoring
Collaboration is key to effective earthquake monitoring. The KGS works with various organizations, including the USGS and the Oklahoma Geological Survey.
These partnerships enhance data sharing and improve the understanding of seismic risks in the region.
Joint projects and studies combine expertise and resources, leading to more comprehensive seismic assessments. Cooperative efforts extend to educational initiatives, where exploration services are provided to train and inform the public about earthquake preparedness.
This collective approach ensures a more robust and effective monitoring system for Kansas and surrounding areas.
