Title Of Article :
Catalogue of focal mechanisms of Moroccan earthquakes for the period 1959-2007; analysis of parameters
Abstract :
We present a brief analysis of the focal mechanisms catalogue of Morocco. Most solutions (129 from 167) were determined for the Central Rif and Alboran earthquakes. The P-axes are mostly sub-horizontal and show mainly a NNW-SSE trend, so as the T-axes but with an ENE-WSW trend. Both axes distribution is in conformity with the general state of stress in Morocco. However, several focal mechanisms determined by different institutions appear to be different or even contradictory and therefore, gives rise to a serious troubles for structural geology studies.
