UNRELEASED PRODUCT — UNDER CONSIDERATION
Status: Under consideration
Last update: 2017-01-11
This catalog will be a compilation of data on non-earthquake seismic sources such as landslide, debris flows, dam collapses, floods, and avalanches that generate seismic signals but are rarely included in common earthquake catalogs.
Exotic seismic sources are non-earthquake seismic sources such as landslide, debris flows, dam collapses, floods, and avalanches that generate seismic signals but are rarely included in common earthquake catalogs. The seismic signals associated with such events contain valuable information about the source time function, energy, and sequence of events that is often not available from other sources.
The Exotic Seismic Events Catalog (ESEC) data product will provide access to source parameter data such as location, and time of the event along with a selection of source-specific parameters for non-earthquake seismic sources that could help to accelerate research in the area of slope failure seismology, which to date has been dominated by only event-specific studies.
The ESEC will initially contain about 100 entries with basic source parameters and references to waveforms. New entries will be added to the database as information regarding new recent and historic events becomes available. The catalog will be searchable and accessible via IRIS’s Searchable Product Depository (SPUD). SPUD will provide a user interface that would allow refinement of source selection parameters and provide a detail page displaying event information along with selected images, maps, links, references and links to all associated materials. Besides pointers to seismic data at the DMC the catalog entries will be simple downloadable text files and associated, source-specific, data such as images (maps, diagrams, photos), GIS files (imagery, shapefiles of outlines). The fundamental source information will include source type, location, and time of the event along with a selection of source-specific parameters (e.g., drop height, runout length, volume).
