There is still a lot of movement on the Kleiner Nesthorn. A constant rumbling could be heard during the night, said the spokesperson at the request of the Keystone-SDA news agency.
It is difficult to predict how the situation will develop. The Lower Birch Glacier was already causing concern on Tuesday. It has recently been moving very quickly at half a meter per day, as Alban Brigger, engineer for natural hazards in Upper Valais, told the media in Ferden.
It is conceivable that part of the rock mass could fall directly onto the glacier. It is also possible that the glacier could thunder forward into the valley, mix with other landslide material and dam up the River Lonza, said Brigger. The experts on site considered the smaller partial collapses to be the best possible scenario.
