title: The Euro-Mediterranean Submarine landSlide database (EMSS25) [Dataset]

description: Description of methods used for collection/generation of data: The EMSS21 displays information collected from both the literature and geophysical records. Data from the literature is collected from georeferenced map figures, from which the outline of the landslide deposit and the landslide scar have been digitized. Most information such as age, volume, typology, inferred trigger mechanism and relationship to fluid flow features and metadata is extracted from the relevant article. Area of the deposit and landslide runout is determined from the digitized polygons and polylines, volume (if not available) is determined from area and mean thickness. If the latter is not available, the volume is determined from the Area-Volume relationship for landslides where volume has already been determined. When the data originates directly from geophysical records the outline and scars have been determined from geomorphological interpretation of swath bathymetric maps and interpretation of submarine landslides on a variety of seismic records. In such instances, age information originates from a variety of methods presenting a wide range of accuracies, from radiometric dating to well-seismic correlation as well as ages inferred from mean sedimentation rates. In many instances, landslides identified in the literature are dated with an age epoch only.-- Data Quality Assurance: The EMSS25 Data quality control is carried out according to the standards and flow chart established by the EPOS Tsunami Thematic Core Services and based on the principles expressed by the EPOS Data Policy.

For these reasons and due to its intrinsic nature, the EMSS25 cannot be guaranteed to be complete, accurate and updated in any part, and will be subjected to successive revisions. Although the Institut de Ciències del Mar of CSIC makes every effort to supply the best available information, no warranty, expressed or implied, is provided as to the accuracy and reliability of all the data supplied in the EMSS25. Users are cautioned to consider carefully the nature of the data and information before using it for decisions that concern personal or public safety. Conclusions drawn from the EMSS25, or actions undertaken on the basis of its contents, are the sole responsibility of the user
description: The Euro-Mediterranean Submarine landSlide database (EMSS25) is a catalogue of several morphological and sedimentary features of submarine landslides of the Mediterranean Sea and the Atlantic and Arctic continental margins of Europe. It also contains limited information from other areas of the world oceans. The catalogue is compiled from results in the scientific literature as well as information collected from geophysical data and not published yet. The data set includes polygons and polylines for the landslide deposits, landslide source areas and landslide scars as well as information relative to age, volume, area, runout, thickness, typology, scar elevation, depth, slope as well as relevant metadata. Deposits, sources and scars are linked/related by the MatchingID field. The catalogue includes submarine landslides that span the Miocene to Present day. Nevertheless a clear bias exist towards submarine landslides of younger age and large size. Smaller events, particularly older than Holocene events, are difficult to map/identify on lower resolution geophysical data sets typically collected in deep-water and large sub-surface depths and are likely underrepresented in the database. The catalogue aims to offer improved understanding of mass-wasting processes, the potentially resulting tsunamis and derived geohazard
