Overview

The tropical cyclone HAROLD-20 was originated on the 1 April 2020 centered between the Solomon Islands and the eastern coast of Papua . Tropical Cyclone HAROLD moved south-east over the Coral Sea and made landfall over southwest coast of Island (North Vanuatu) on 6 April 2020 around 00.00 UTC, with maximum sustained winds up to 215 km/h.

Based on data of the expected tropical cyclone path of wind speeds zones from Joint Research Centre (Issued on 6 April 2020 00:00 UTC), and population data from WorldPop 2020, UNITAR-UNOSAT conducted a population exposure analysis for Vanuatu. About 42%, of population of Vanuatu living inside wind speed zone of 120 km/h, 9% living inside wind speed zone of 90 km/h and 39% living inside wind speed zone of 60 km/h. About 24%, 7% and53% of buildings in Vanuatu are expected to experience more than 60, 90 and 120 km/h wind speed zone accordingly.
