Fluid emissions of non volcanic origin and mud-volcanoes on seafloors, mapped by various national and regional mapping projects and recovered in the literature. Polygons represent areas larger than 4 hectares. (for smaller areas, see fluid emissions points layer) Note: 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. Points refer to specific morphotypes or 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 landslides scarps, detectable on the seabed, 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 events which originated tsunamis, mapped by various national and regional mapping projects and recovered in the literature. Wherever possible, connected events reported in other EMODnet Geology layers are indicated in the Attribute table. Note: 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 volcanic structures and eruption centers, mapped by various national and regional mapping projects and recovered in the literature. Lines represent eruptive fissures or borders of lava flows. 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.

Fluid emissions of non volcanic origin and mud-volcanoes on seafloors, mapped by various national and regional mapping projects and recovered in the literature. Points represent areas smaller than 4 hectares. (for larger areas, see fluid emissions polygons layer) Note: blank areas do not necessarily correspond to no occurrence.

Submarine mud-volcanoes and fluid emissions of non volcanic origin, 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.
