Ongoing global historical database of related tsunami source-event and observed runup-location tables, spanning 2100 BC to the present. It emits event source/time/location, cause, validity, magnitude/intensity, maximum water height and historical effects plus runup observation location, arrival/travel time, measurement type, water height, horizontal inundation and location effects. Reporting is heterogeneous and is neither a completeness claim nor prospective hazard. Pin DOI 10.7289/V5PN93H7, retrieval date/query and API schema.
