Description :

In the early morning on May 19, 2010, a large deep-seated landslide occurred at Gírová Mountain, Outer West Carpathians, Czech Republic. The area where this landslide happens is the region of pre-existing deep-seated gravitational deformation. The size of the landslide is approximately 1060 meters long and 200 meters wide. The thickness of the landslide ranges from around 10 meters in the lower part to around 30 meters in the upper area. The entire sliding mass has a volume of roughly 2.8 million cubic meters and the estimated displacement varies from about 75 meters to 253 meters. No-one was injured and no properties were damaged. The precipitation fell from May 15th to 18th (few hours before the initiation of the landslide) is considered as the main factor inducing the landslide. The total amount of the rainfall was 244.6 mm with the maximum daily precipitation was 115.1 mm and the minimum daily precipitation was 12.4 mm. The Gírová landslide is a good case study on inducing factors and process of liquefaction at mountain slopes. This case study also confirms the theory that large active landslide often progresses inside existing unstable regions.
