This research paper aims to present a framework for identifying multi-hazard events from a global disaster database and reclassifying them into different categories. EM-DAT data is used to identify and classify multi-hazard events from 1900 to 2023 at a global scale.

Technical considerations

The study defines multi-hazard events as simultaneous, cascading, or cumulative occurrence of multiple natural hazards. Data is available on request.
