Week 8: Mass Wasting Hazards

 

Finland is not known to have many landslides but they have occurred.  According to Think Hazard Finland is labeled as a very low threat to landslides.  Finland does have rainfall patterns, there terrain and slope, and also possibly earthquakes can make landslides a rare phenomenon if this hazard does occur.  Northern Finland has a larger amount of landslides due to its amount of rainfall and also the amount of seismic activity that occurs there.  According to ScienceDirect the amount of landslides has increased to a total number of 121 landslides in Northern Finland since the introduction of the systematic screening of LiDAR DEMs by Palmu et al in 2015.  

With how rare landslides are in Finland it is hard to find when the largest landslide in the history of Finland was.  However in 2011 a large windstorm called Cyclone Dagmar swept overt he nordic countries in Europe causing there to be small amounts of rockslides in Finland and for other mass wasting hazards to occur.

Here is a map that shows the fault and seismic activity in Finland that could be the cause of the larger amount of landslides in Northern Finland.
