Résumé

<p>Rotational seismology refers to the study of the 3 components of rotation that are part of the<br>seismic wave field equation (Aki and Richards, 2002). Using the Geodetic Method (GM)<br>[Spudich et al, 1995], that is, using spatial finite differences of the local ground motions, the<br>3C of rotations were calculated at the dense broadband seismic array of the LSBB (Low<br>background noise underground research Laboratory, France, http://lsbb.eu). A catalog of 3C<br>rotations was created by systematically applying this method to several seismic events. The<br>uncertainty of the rotation measurements has been estimated through a sensitivity analysis.<br>This catalog will be presented and illustrated using examples. The analysis of the rotational<br>motions relatively to the seismic events source&#8217;s properties will be discussed as well.</p>
