It looked violent when a large part of the Stampa massif came loose above the E16 in Aurland earlier in July. But the slide that was caught on video by the avalanche monitoring was just a foretaste of what could come. A stone’s throw away lies the Joasetbergi – Norway’s largest unstable mountain range and also part of the so-called Stampa massif. Here, 285 million cubic meters of rock still lie in the unstable mountain. At some point, a large landslide could lead to a large tidal wave that hits several tourist villages in Sogn. According to NVE, the wave will be 4 meters high when it washes over the tourist village of Flåm, and 2.5 meters when it hits the municipal center Aurlandsvangen. This is what it looked like when it fell from Stampa earlier in July. Unchanged truth to loosen Although the rock masses that were loosened over the E16 and the tidal wave mountain Joasetbergi are part of the same mountain massif, they are not directly connected. Nor can they influence each other, say the experts news has spoken to. There is therefore neither greater nor less likelihood of a tidal wave following the landslide incident earlier this summer. – Joasetbergi has an unwavering sense of fairness to loosen up. We will continue to monitor as we have done, says geologist Gustav Pless at NVE. Over several years, NVE has continuously monitored the area, which is the sogningen’s answer to Åkraneset in Geiranger, known through the fictional film “Bølgen”. Most likely, they will be able to foresee an avalanche years or months in advance. The unstable mountain range Joasetbergi. Geologist and associate professor Thomas Scheiber at Høgskulen på Vestlandet emphasizes that one must not be worried about Joasetbergi collapsing, even if masses of rock in the vicinity have become loose. – Each unstable object lives its own life. We haven’t seen any changes in speed and movement in Joasetbergi when the landslide happened. He says that the stone block that collapsed had moved more than two meters in recent years, while Joasetbergi moves at around one centimeter a year. If this part of the mountain were to loosen, they would see increased movements months and years ahead. – With such large objects, a landslide will not happen from one day to the next, emphasizes the geologist.

It fell a little here and a little there, says Ragnhild Hide. She and her husband Bernt Harald Hide live close to where it collapsed this summer.

Nor does he think about the tsunami danger until today. – If we were to think about it, we would have to stay at home the whole time. You are aware of it, but you can’t go around thinking about it. Then you become a complete nervous wreck, says Merkesdal In recent times, several large landslides have wiped out entire rural communities in Norway, the Tafjord accident in Møre and Romsdal claimed 40 lives in 1934. A total of 135 people died in Lodalen in Stryn where Ramnefjellet took the village together three major landslides in the years 1905, 1936 and 1950. The tourist and cruise village of Flåm could, in the worst case, be hit by a four-metre-high river wave if NVE’s worst-case scenario strikes. Photo: Sondre Dalaker / news
