Statement: landslide scar from helicopter
Abstract: A helicopter flies over a landslide scar in Maierato, Southern Italy.
Most of the sliding happened on February 15th, 2010, but the area is notorious for landsliding and the hillslope was moving previously as well. This area of Italy, Calabria, is known for its landslides. Heavy rains preceded the event and caused ~100 other smaller slides in the region.
Theory
This landslide is a typical example of a deep-seated landslide. These are landslides in which the sliding surface is below the maximum rooting depth of trees (typically to depths greater than ten meters). The video shows a scar in the hillslope of several 10's of meters high. It can also be seen that there is a very deep weathered soil (or regolith). These events typically move slowly, only several meters per year, but occasionally move faster. This is what happened in this event, the slide already showed slow movement before speeding up. The people living in the town of Maierato were evacuated in time. Whereas the video show the fresh scar, such hillslope scars can be mapped by concave scarps at the top and steep areas at the toe for many years after.
