During the 1991 event the slush flow provoked lateral and vertical scouring of the Gilbakkagil gully at the fan apex following the channel straight down from the gully mouth. Then, part of the slush spread out on the southern part of the fan, but most of the slush material followed the channel down the fan, towards the sea. The thickest accumulation occurred in the apex zone of the fan. There 10 to 20 m thick mixed deposits of snow and rock fragments occurred. In the middle part of the fan, the slush deposits were up to 175 m wide, and up to 5m high. Further down, in the inhabited area, the main part of the snow and rock fragments accumulated on and above the main road, and ca. 5500 m³ of debris were removed from the road. The 1994 event was smaller and did not spread out in the apical zone; instead, the slush flowed down the channel towards the sea, mostly within debris levées that was built by previous slush and debris flows. The flow accumulated debris in the channel and filled the drainage pipe underneath the main road.

The 1991 and 1994 events deposits highlight the remarkable capacity of slush flows to transport a high debris load, contributing to build up multiprocess colluvial fans with material from fine-grain size to boulders larger than 1 m. From 3000 to 4000 m³ of rock fragments were transported in 1991, and it is assumed that the 1994 event mobilized ca. 3000 m³.
