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).

Data Description 

The multi-hazard event sets are provided in a .csv file, where the events are defined in the ‘Event’ column, and each row corresponds to a single hazard in an event. The following table describes the columns present in MYRIAD-HES:

Variable

Format

Description

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
