Four earthquakes rattled the area around Edgefield on March 9, with magnitudes ranging from 3. 1 to 4. 0 in a burst that lasted under 10 minutes. The sequence, described in U. S. Geological Survey data and followed by a separate small tremor near Coushatta, signals a concentrated pattern of seismicity in Red River Parish that merits continued monitoring of any earth quake activity.
USGS and Edgefield: Four March 9 Quakes in Under 10 Minutes
On March 9, four events struck within about 10 minutes between 4: 33 and 4: 41 a. m. CT, which is 5: 33 am ET to 5: 41 am ET. The first two registered magnitude 3. 1, the third reached magnitude 3. 9, and the fourth measured magnitude 4. 0, each occurring at an approximate depth of 3. 1 miles. Locations clustered tightly: roughly 2. 5 miles northwest of Edgefield, about 1. 9 miles north-northeast and northeast of the village, and about 5 miles west-northwest of Edgefield. Residents reported feeling shaking as far south as Coushatta and as far north as Minden.
Earth Quake Cluster Near Edgefield Follows 4. 9 Magnitude Event in Red River Parish
These March 9 shocks arrived just four days after a magnitude 4. 9 event in the same Red River Parish area, the strongest on record for the state. Two of the four March 9 quakes now rank among the four strongest earthquakes on Louisiana’s record. A local weather team separately recorded a magnitude 2. 5 quake 3 miles southwest of Coushatta at a depth of approximately 3 miles, and smaller tremors in recent months have been noted across the region, prompting concern among residents about the cluster of earth quake activity.
If Edgefield activity continues, more quakes could join Louisiana’s strongest on record
If the Edgefield series persists, the immediate directional signal is an increased share of larger local events entering the state’s historical record. The context shows a rapid escalation in scale: a magnitude 4. 9 within days, followed by four quakes in under 10 minutes on March 9 that included magnitudes near 4. 0. Should a similar burst repeat, additional entries from Red River Parish could displace older entries in the state’s top records.
For now, the most concrete metrics are magnitudes, epicenter proximity and reported felt areas. The March 9 cluster’s shallow depths around 3. 1 miles and the proximity of multiple epicenters within a few miles of Edgefield are specific signals pointing to continued, localized seismicity rather than isolated distant shocks.
Yet, the context does not resolve the underlying cause of the clustering or whether any structural damage occurred. It is unknown if any damage, injuries or deaths have been reported. An official damage and injury assessment from local authorities or subsequent USGS statements would be the confirming signal that clarifies impact and severity beyond raw magnitude and location data.
Next confirmed milestones named in the context are continued monitoring and updates from the Red River Parish Sheriff’s Office and ongoing tracking by local weather and seismic teams. Expect those updates to be the next firm data points that either reinforce the current trajectory of clustered events or show the activity tapering off.
