Alta Norway Mudslide - Often Disaster Can be Predicted
The tragedy of the eight houses being swept into the ocean may have been prevented. Norway has quick clays and they are not very strong soils.
There could be historical data that told of other past mudslides in this area. Geologic mapping might identify them as you see below.
You can also look at geology maps like this and get a clue based on rock formations that have a history of landslides:
This is a copy of a United States Geologic Survey (USGS) geologic topographic map of the East End of Cincinnati, OH. The downtown area would be just to the left of what you see. The Kope and Lower Fairview formations are the light pink rock just above the magenta alluvium that's north of the Ohio River. (C) Copyright 2017 USGS and every US taxpayer that owns the maps.
