Regardless of their frequently harmful and unpredictable nature, landslides offer attention-grabbing templates for learning how soil organisms, vegetation and animals reply to such destruction. The rising box of landslide ecology is helping us comprehend those responses, supporting slope stabilisation and recovery and contributing to the growth made in geological techniques to landslide prediction and mitigation. Summarising the starting to be physique of literature at the ecological effects of landslides, this e-book offers a framework for the promoting of ecological instruments in predicting, stabilising, and restoring biodiversity to landslide scars at either neighborhood and panorama scales. It explores nutrient biking; soil improvement; and the way soil organisms disperse, colonise and engage in what's frequently an inhospitable setting. Recognising the function that those tactics play in offering options to the matter of volatile slopes, the authors current ecological ways as helpful, reasonable and resilient supplementations to landslide administration.

3). Submarine landslides can be much larger and more massive than terrestrial landslides. The largest known is the prehistoric Agulhas landslide off the coast of South Africa that is 750 km long and has an estimated volume of 20 000 km3 (about 150 times larger than the largest terrestrial landslides; Schuster, 2001). Other large prehistoric landslides are found off the coasts of Norway and Hawaii. , 2006) cover more surface area than the current total land mass of all the islands. , Chaytor et al.

S. 1 Storegga: a massive submarine landslide Recent advances in remote sensing of submarine landslides are showing just how unstable the ocean floor can be, particularly along continental margins. One of the largest submarine landslides ever measured is Storegga (“Great Edge”), located 100 km off the coast of Norway. It is so large that it reaches half the distance from Norway to Greenland (Fig. K. ; Nisbet & Piper, 1998). , 2004). The remaining three phases were shorter and smaller in volume and continued the erosion toward the coast of Norway.
