In Bærum, a climbing accident at the popular Nedre Sydstup area on Kolsås was caused by a rock that cut the climbing rope, according to Odd Magne Øgreid, leader of the safety committee of the Norwegian Climbing Federation. The injured climber, described as very experienced, is out of life-threatening danger, police attorney Elias Settevik said. Two other people were slightly injured in the incident, multiple reports indicate. The climbing area is one of the most popular in the Oslo region, and loose rock is a known issue there, especially in spring, according to Øgreid and Emil Ohlsson of the local climbing club. Ohlsson told NRK Stor-Oslo that the club does not practice closing climbing areas after accidents or due to loose rock.
In Rogaland, a rockfall near Giljajuvet injured a person who was flown to Stavanger University Hospital. The person was conscious when emergency services arrived, according to operations leader Jostein Jaarvik Reiestad and watch leader Svein Nesse. The cause of that rockfall remains unknown. In Tvedalen, a person was hit by a rock in a large rockfall and received life-saving first aid before being taken to hospital, multiple reports said. The area has been cordoned off pending a geologist assessment, according to incident commander Terje Lunden. The extent of the person's injuries has not been disclosed.
In Trøndelag, a man fell into a deep gorge and is trapped under a rock. He is awake and a rescue helicopter is en route, according to Trøndelag politidistrikt. The outcome of the rescue operation is not yet known. In other incidents without injuries, a 500-kilogram rock fell onto a staircase at a house in Lerstad, Ålesund. The Labour Inspection Authority is following up and has requested documentation on risk assessments, according to Hallvard Solevåg of Arbeidstilsynet. A rockfall on Herøyavegen in Porsgrunn blocked a road and a pedestrian and cycle path; the rock weighed an estimated couple of tons, operations leader Ståle Fuglaas said. A rockfall also occurred on a hiking trail in Holmestrand with no injuries reported.
These incidents highlight the persistent risk of rockfalls in Norway, a country with rugged terrain and popular outdoor recreation areas. One notable geological feature is Gloppedalsura, a massive scree formation in Gloppedalen valley, Rogaland county. Recognized as the largest scree in Northern Europe, it consists of avalanche boulders piled on top of an end moraine. The formation was created approximately 10,000 years ago at the end of the last Ice Age. Glacial retreat deposited an end moraine, damming the river to create a temporary lake in Byrkjedalsgryta. Freeze-thaw cycles then triggered a catastrophic landslide from the southern mountainside, releasing house-sized angular boulders. The river carved a ravine through the deposit, rerouting its course toward Gilja and Giljajuvet. The boulders vary in size from smaller fragments to house-sized blocks weighing thousands of tons, lying at elevations from 100 to 300 meters above sea level. Terraces in Byrkjedal at 240 metres altitude are evidence of the moraine-dammed lake. The site was used as a defensive position by Norwegian forces during fighting against German invaders in April 1940, and today there is a via ferrata climbing route at Gloppedalsura.
The recent rockfalls have prompted renewed attention to safety measures in climbing and hiking areas. While the climbing club in Bærum does not close areas after accidents, the incidents have led to discussions about risk management. The condition of the seriously injured climber in Bærum remains unclear, as does the cause of the Rogaland rockfall. The extent of injuries for the person hit in Tvedalen and the outcome of the rescue in Trøndelag are also unknown. Authorities continue to monitor the situation and assess geological hazards.
