Faultplane solutions (lower hemisphere, equal area projection) for the Tafers, Matran and Düdingen events of 2009. Take-off angles of the rays at the source are consistent with those calculated by Kastrup et al. (2007) for the Fribourg sequences of 1987, 1995 and 1999. The discrepant observation (Down) for the Düdingen event is station STAF, at an epicentral distance of only 4 km, and could therefore be due to a slight error in location and consequently in the calculated azimuth of the ray
