MYRIAD – Hazard Event Sets (MYRIAD-HES)

<p>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).</p> <p>These multi-hazards event sets have been compiled using the MYRIAD &ndash; Hazard Event Sets Algorithm&nbsp;(MYRIAD-HESA).</p> <p>If you have used MYRIAD-HES in your work, please cite our paper:</p> <p><strong>Claassen, J.N., Ward, P.J., Daniell, J.&nbsp;<em>et al.</em>&nbsp;A new method to compile global multi-hazard event sets.&nbsp;<em>Sci Rep</em>&nbsp;13, 13808 (2023). https://doi.org/10.1038/s41598-023-40400-5</strong></p> <p><strong>Data Description&nbsp;</strong></p> <p>The multi-hazard event sets are provided in a <em>.csv</em> file, where the events are defined in the &lsquo;Event&rsquo; column, and each row corresponds to a single hazard in an event. The following table describes the columns present in MYRIAD-HES:</p> <table> <tbody> <tr> <td> <p><strong>Variable</strong></p> </td> <td> <p><strong>Format</strong></p> </td> <td> <p><strong>Description</strong></p> </td> </tr> <tr> <td> <p>Event</p> </td> <td> <p>&quot;Event&quot; + #</p> </td> <td> <p>The event number of a unique event. Rows with the same event number contain the hazard information of the individual hazards in that event</p> </td> </tr> <tr> <td> <p>Hazard</p> </td> <td> <p>name</p> </td> <td> <p>The hazard type</p> </td> </tr> <tr> <td> <p>code</p> </td> <td> <p>&quot;Acronym&quot; + #</p> </td> <td> <p>The unique hazard code</p> </td> </tr> <tr> <td> <p>starttime</p> </td> <td> <p>yyyy-mm-dd</p> </td> <td> <p>The start time of the hazard</p> </td> </tr> <tr> <td> <p>endtime</p> </td> <td> <p>yyyy-mm-dd</p> </td> <td> <p>The end time of the hazard</p> </td> </tr> <tr> <td> <p>Intensity</p> </td> <td> <p>varies, NaN if not Intensity information is known&nbsp;</p> </td> <td> <p>The intensity of the hazard if applicable</p> </td> </tr> <tr> <td> <p>Unit</p> </td> <td> <p>varies,&nbsp;NaN if not Intensity information is known&nbsp;</p> </td> <td> <p>The unit of the intensity</p> </td> </tr> <tr> <td> <p>Geometry</p> </td> <td> <p>Well-Known Text (WKT)</p> </td> <td> <p>The geometry of the hazard footprint</p> </td> </tr> </tbody> </table> <p>&nbsp;</p>
