At the beginning of the second pitch on birds land, between 1st and 2nd bolt, a big rock (around half of a car) was pull down and the climber fell and luckily dodged the major rock but minor injuries were caused by the subsequent loose rocks. He fell around 3-4 meter to a ledge which damaged his helmet but apparently no concussion were observed. The belayer lowered him and rappel himself from anchor of first pitch but realized later that the rope were cut by the falling rock almost all the way through at two spots.
