摘要：

Fault plane solutions for 128 earthquakes which occurred in France and neighbouring areas have been determined. Stress field information given by these data are discussed in relation to previous tectonic knowledge. The Western Alps are characterized by a compressional regime with a fan-shaped distribution of P axes, which might be related to the interaction mechanism between Europe and the Adriatic plate. The Pyrenean region is mainly submitted to a south-north compression. Tectonic activity in this area seems to be determined by the presence of two subduction zones with reverse dips, in the South Bay of Biscay and in the Central Pyrenees. The transition zone between these two active belts is characterized by significant seismicity with a transpression regime. © 1990.
