According to the state geologist, it is too early to draw conclusions about what triggered the landslide.
"Exactly what this is due to is just speculation. But it's a bit scary considering the buildings in the area, gas station and parking lot for trucks," says Christian Öhrling.
Construction work near the site of the collapse
At the collapse there is a slight slope with a lot of mud and rock higher up, he says. Construction work is underway up the mountain.
"A lot has been built and it has worked so far. But when large excavated masses are moved on the clays, and with these amounts of rain, there is always a risk," he says.
Highly sensitive clays
He also says that in Sweden there are very sensitive clays.
How can this happen?
"When water levels change, things can happen, and especially by a trigger such as load changes and shaking," he says.
