Comparison of Pg and Pn arrival times of the 2009 Vaduz and the 2010 Feldkirch events recorded at five stations located at practically the same azimuths and distances from the two epicenters. The observations are aligned so that the Pg arrivals coincide, assuming a Pg velocity of 6 km/s. The coincidence of the Pn arrivals demonstrates that the focal depths of the two events must be identical
