Maryland isn’t known for frequent or large earthquakes, but it does experience them occasionally.
In the past 10 years, Maryland had its strongest recent earthquake on April 5, 2024, with a magnitude of 4.8. This earthquake struck 138 miles northeast of Baltimore. The region has a moderate risk for earthquake damage.
The Maryland Geological Survey has set up a Seismic Network to monitor and provide real-time data on local seismic activity.
This monitoring helps in understanding the patterns and potential risks associated with earthquakes in the area.
While rare, significant seismic events can still occur, making it essential to stay informed and prepared.

This resource provides up-to-date information and helps residents and researchers keep track of seismic activities in the region.
Historical Seismic Activity in Maryland
Maryland has experienced numerous earthquakes, with some notable events that have been recorded over the years. The state has established systems to monitor and record seismic activities.
Notable Earthquakes in Maryland’s History
Maryland has felt earthquakes as far back as 1758. Since then, the state has been the epicenter of felt earthquakes 66 times, averaging about one earthquake every three years.
A notable event was the earthquake near Columbia in 1993, which had a magnitude of 2.7.
More recently, the magnitude 5.8 earthquake in 2011, centered in Mineral, Virginia, caused significant impact felt across Maryland.
In Baltimore, there have been several mild quakes, though none have caused major damage. Overall, strong earthquakes are unusual in the region, but historical records show a consistent pattern of minor to moderate seismic activity.
Seismic Networks and Monitoring
To understand and monitor earthquake risk, Maryland has developed a seismic network managed by the Maryland Geological Survey.
This network provides real-time data on local earth movements.
The state currently has two seismometers, crucial for tracking and recording seismic activity.
These instruments help scientists and the U.S. Geological Survey analyze quake patterns.
Data from various periods have been compiled, including contributions from the Lamont-Doherty Earth Observatory and the Delaware Geological Survey.
This collaboration helps maintain a comprehensive record of seismic events and improves earthquake preparedness and response.
Understanding Earthquake Risks in Maryland
Maryland experiences occasional seismic activity, mostly minor in magnitude. The risks vary by location and preparedness. This section dives into seismic zones, frequency, and mitigation strategies.
Seismic Zones and Fault Lines
Maryland falls within a region with low to moderate seismic activity. The Columbia and Howard County areas report the most frequent earthquakes.
These zones experience clusters of small quakes rather than isolated events. Major fault lines are outside Maryland, but ground shaking can occur due to distant seismic activity.
Nationally, areas like the eastern United States have recorded rare yet impactful quakes. Monitoring systems, such as the Maryland Seismic Network, track these movements to provide real-time data.
Magnitude and Frequency
Most earthquakes in Maryland are minor, typically ranging from magnitude 2.0 to 3.0.
Significant quakes, while rare, have occurred, such as the 2011 Virginia earthquake, which affected Maryland.
In a 50-year period, the likelihood of a damaging quake is low but not zero.
Ground shaking felt in Maryland often originates from quakes in nearby states like Virginia and South Carolina. Understanding the magnitude range helps in evaluating seismic risk and impacts on local structures.
Preparedness and Mitigation Strategies
Preparedness is crucial despite the low frequency of severe earthquakes in Maryland.
Residents should secure heavy furniture, create emergency plans, and purchase earthquake insurance.
Public buildings are often designed to withstand mild shaking, but older structures may need retrofitting.
Community education programs can improve readiness and response times.
Insurance rates may be higher in areas with greater risk, so consulting with local authorities on best practices is advised.
Implementing these strategies can reduce potential damage and ensure safer communities.
