The study finds that seismic activity during the Le Teil earthquake was largely controlled by local geological rheology.
Investigations showed that the mainshock nucleated in marly-limestone at a depth of 1 km before propagating primarily in a lateral direction.
Seismological and INSAR data were used to develop a kinematic rupture model that detailed the fault's geometry and behavior during the earthquake.
Aftershock distribution patterns indicate that these ruptures occurred in materials with varying thickness, primarily in marls and marly limestone.
