MYRIAD – Hazard Event Sets (MYRIAD-HES)

A global multi-hazard event set database, spanning from 2004 to 2017, which includes eleven hazards (coldwaves, heatwaves, droughts, earthquakes, extreme wind events, floods, landslides, tropical cyclones, tsunamis, volcanic eruptions, and wildfires). These multi-hazards event sets have been compiled using the MYRIAD – Hazard Event Sets Algorithm (MYRIAD-HESA).

The following table describes the columns present in MYRIAD-HES: <strong>Variable</strong> <strong>Format</strong> <strong>Description</strong> Event "Event" + # The event number of a unique event. Rows with the same event number contain the hazard information of the individual hazards in that event Hazard name The hazard type code "Acronym" + # The unique hazard code starttime yyyy-mm-dd The start time of the hazard endtime yyyy-mm-dd The end time of the hazard Intensity varies, NaN if not Intensity information is known The intensity of the hazard if applicable Unit varies, NaN if not Intensity information is known The unit of the intensity Geometry Well-Known Text (WKT) The geometry of the hazard footprint
