 The loud noise of the rockfalls, break-offs and fractures were already heard during the Sunday service on the morning of September 11, 1881.In spite of this, next to nobody left the dangerous area – in fact, many spectators went to the affected area or climbed to the nearby hamlet "Düniberg" on the opposing face of the valley in the hope of enjoying a better view of the spectacle.In the late afternoon, after two smaller rock slides, 10 million cubic meters (353 million cubic feet) of slate broke off, travelled 2 km (1.24 miles), and destroyed 90 hectares (222.4 acres) of land.
