The largest inland earthquake in Louisiana history was recorded Thursday near Edgefield.
It was a 4.9 magnitude earthquake.
The only larger earthquake was recorded offshore in the Gulf, south of Grand Isle, at magnitude 5.3, in February 2006.
Here’s what’s interesting: While we wait for geologic surveys to determine any unknown faults in this region, there has been an uptick in seismic activity in Northwest Louisiana and East Texas, with 10 smaller earthquakes since December 4.
This zone is called the “Haynesville-Bossier Shale,” which is a location of major natural gas fracking with large deposits of this resource being extracted.
Could hydraulic fracturing or “fracking” be causing the increased seismic activity? It’s possible.
It is interesting to note the overlay in seismic action with where deposits are being extracted.
