A map of submarine landslide susceptibility in European seas. High susceptibility values indicate a high probability of landslides. This map cannot be compared to the accuracy of studies based on detailed investigations, but provides an overall view on the distribution of landslides susceptibility. The map indicates the probability that landslides may occur in that portion of the seafloor over time, but does not measure when or how frequently an event may occur, nor its possible size. For more details refer to: “Submarine landslides: mapping the susceptibility in European seas”, C. Innocenti, L. Battaglini, S. D'Angelo and A. Fiorentino, Quarterly Journal of Engineering Geology and Hydrogeology, 54, qjegh2020-027, 23 October 2020, https://doi.org/10.1144/qjegh2020-027
-
Submarine landslides, visible on the seabed, mapped by various national and regional mapping projects and recovered in the literature. Points refer to landslide areas smaller than 60 hectares. Note: Project is ongoing and the work is in progress; blank areas do not necessarily correspond to no occurrence
-
Submarine tectonic lines, mapped by various national and regional mapping projects and recovered in the literature. Note: Project is ongoing and the work is in progress; blank areas do not necessarily correspond to no occurrence.
-
Locations of coasts affected by tsunamis of unknown origin, mapped by various national and regional mapping projects and recovered in the literature. In order to allow representation of different events, affected coasts are represented by points located in an average position for each event. Note: blank areas do not necessarily correspond to no occurrence.
-
Submarine volcanoes, mapped by various national and regional mapping projects and recovered in the literature. Lines refer to eruptive fissures or borders of lava flows. Note: Project is ongoing and the work is in progress; blank areas do not necessarily correspond to no occurrence.
-
Submarine landslides scarps, detected on the seabed, mapped by various national and regional mapping projects and recovered in the literature. Note: blank areas do not necessarily correspond to no occurrence.
-
Submarine volcanoes, mapped by various national and regional mapping projects and recovered in the literature. Locally occurrences include their emerged portions. Note: Project is ongoing and the work is in progress; blank areas do not necessarily correspond to no occurrence.
-
Quaternary submarine tectonic lines in geologically active areas, mapped by various national and regional mapping projects and recovered in the literature. Note: blank areas do not necessarily correspond to no occurrence.
-
Submarine landslides, detected on the seabed, outcropping or buried, mapped by various national and regional mapping projects and recovered in the literature. Points represent landslide areas smaller than 4 hectares. (for larger areas, see submarine landslides polygons layer) Note: blank areas do not necessarily correspond to no occurrence.
-
Submarine landslides, detected on the seabed, outcropping or buried, mapped by various national and regional mapping projects and recovered in the literature. Locally polygons are extended on land to include the subaerial portions and/or origin of the landslides. Polygons represent areas larger than 4 hectares. (for smaller areas, see submarine landslides points layer) Note: blank areas do not necessarily correspond to no occurrence.
