Catalogue coverage
Counts describe source records. One tsunami can have many coastal observations and multiple historical accounts. NOAA event IDs link documented observations; Greek reports retain their own identity when there is no shared identifier. Records without coordinates remain searchable and included in relevant statistics.
Statistics describe filtered source records, not independent disasters or a globally complete hazard frequency. Select a record type or source before interpreting distributions. Event maxima and local water heights are separate variables. Missing values and qualitative casualty ranges are excluded from numerical calculations; they are never treated as zero. Negative years denote BCE using the source year convention.
Source library
Use the citation and reuse terms of each inventory.
Methods and reuse
Preserve attribution with downloads.
The complete NOAA feature layers were downloaded in stable object-ID order with pagination. Stable NOAA ID and TSEVENT_ID fields supply provenance and event–observation links. Original text, classifications and coordinates are preserved. Greek blank rows and zero magnitude placeholders are excluded from numerical measures. No proximity-based merges or invented inundation polygons are made.
Original platform text and interface design are CC BY 4.0, except separately credited source data, imagery, basemaps and logos. Source materials retain their original reuse terms.
Contribute a documented record, an inventory or a correction, with its original evidence.
Prepare your submission
Use one row per source record. Leave unknown values blank; include the original identifier and reuse terms. Attach original geometry with its coordinate reference system where available.
