N2 - On January 25th, 2010 at about 8 p.m. a 432 m3 large and 1,026 t heavy block was released from a conglomerate face, apparently without warning, destroying a family home at the village of Stein at the river Traun. Only two of four inhabitants could be saved out of the debris by means of a spectacular rescue operation by the local fire brigade. After this event the question arose whether the rockfall could have been foreseen or if such spontaneous incidents are abrupt and unpredictable. In this paper, the studies conducted to reconstruct the processes leading to this event are presented. These investigations included field mapping, geodetic survey, laser scanning and stereographic photogrammetry of the rupture face, mineralogical analysis of sinter crust thin sections, inventory of the block dimensions and reconstruction of the collapse kinematics, analysis of the weather data prior to the event and a 2D finite element calculation (Phase2, Rocscience) using the geometry of the overhanging conglomerate strata.
