Sorry to hear that admission
but landslides in Norway have been happening well before the Vikings roamed the lands of Scandinavia
so has heavy rainfall
and intense wave action
Norway's fjords were formed by melting glaciers well before mankind made an appearance
What causes landslides in Norway?
Landslides can happen when heavy rain or floods weaken the ground by saturating soil with water.
The loosened ground can come apart and send masses of land careering down hills or cliff-edges.
Dr Mohammad Heidarzadeh, secretary general of the International Tsunami Commission, told MailOnline Norway is a prime spot for landslides because of the country's soft clay soil.
He said: 'The coast is made of loose clay material which when combined with heavy rainfall or intense wave action, becomes susceptible to failing and sliding.'
