Landslide locations and extents Ireland (ROI/NI) ITM

Landslide locations and extents help us locate where landslides have occurred. Ireland's location, terrain and climate result in landslides occurring mainly in areas with steep slopes where rock meets the surface and peat covers the terrain. Landslides have the potential to cause great havoc, and have done so all around the world. They have resulted in loss of life and damage to infrastructure. Landslides can damage roads, railways, canal embankments, and cause dams to fail. They can destroy or severely damage buildings of all types – housing, commercial or industrial property. Rivers can become blocked or diverted by sediment or rock displaced by landslides. A map of landslide locations can be used when planning large scale infrastructure projects such as roads, wind farms and housing. Understanding where landslides can occur will help prevent future damage to any structures built. A landslide is the movement of material down a slope. This includes rock, earth, mud and peat. Landslides in Ireland mainly occur on steep mountain slopes. Geologists map and record information on where and when landslides happen and on the material that has moved. To produce this dataset landslides were mapped using digital imagery and mapping in the field. We collect new landslide location data and update the landslide location dataset every year. This is a vector dataset. Vector data portray the world using points, lines and polygons (area). The landslide location data is shown as points. Each point holds information about the landslide event, its date, its location, the type of landslide (topple, bogslide, flow), the type of material (peat, earth, rock) and the cause of the landslide (heavy rainfall). he landslide extent perimeter data is shown as polygons which is the area of the landslide. Each polygon holds information about the landslide event, its date, its location, the type of landslide (topple, bogslide, flow), the type of material (peat, earth, rock) and the cause of the landslide (heavy rainfall).
