Tsunami occurrence and runup history

The governmental, non-contributory HazEL product provides standing unauthenticated retrieval of linked tsunami events and runup observations for arbitrary geographic and time filters. Event outputs identify date, location, cause, validity, and tsunami magnitude or intensity; runup outputs identify the linked event and date, observation location, measurement type, water height and horizontal inundation in metres, arrival or travel time, validity, and checked-quality flags. Pin DOI 10.7289/V5PN93H7, the selected geography and query, retrieval date, and API schema. Treat the answer as heterogeneous historical observations, not a completeness claim or prospective hazard evidence, and do not imply an immutable record revision timestamp.
