Impact and aftermath
July 2021
As tropical storm one made landfall in Bangladesh, it brought winds of 70 mph and a storm surge up to 3 meters high and heavy torrential rains and flooding, killing around 11,069 people. Every single person on the island of Urir Char, approximately 500 at the time, is thought to have been swept into the Bay of Bengal. A pilot who flew over the island said it was swept by waves, like it was inside the fireball on an atomic bomb. A total of 1.3 million people were affected. Approximately 137,000 homes were damaged, 102,000 of them were destroyed, 133,00 acres of crops damaged, and 120,000 cattle were killed. The country was relying on a few air force helicopters and some vessels to transport supplies to the survivors of the affected region and it was stated that many areas were still not reachable.1985-05-28 Toll 3,000 and Rising in Bangladesh Cyclone : 'Looked Like Nuclear Holocaust,' Witness Says of Islands Ravaged by Storm and Tidal Wave https://www.latimes.com/archives/la-xpm-1985-05-28-mn-16253-story.html 2026-05-17 Los Angeles Times en-USRahman Khan Sirajur Cyclone Hazard in Bangladesh http://www.adpc.net/casita/case_studies/coastal%20hazard%20assessment/modelling%20cyclone%20hazard%20in%20bangladesh/background_information_on_the_storm_surge_modelling.pdf ADPC.net https://web.archive.org/web/20071119115544/http://www.adpc.net/casita/Case_studies/Coastal%20hazard%20assessment/Modelling%20cyclone%20hazard%20in%20Bangladesh/Background_information_on_the_storm_surge_modelling.pdf 19 November 2007 4 December 20151,400 Dead in Bangladesh; Toll Rising : Island Leveled by Cyclone, Tidal Wave; Thousands Homeless https://www.latimes.com/archives/la-xpm-1985-05-27-mn-6276-story.html Los Angeles Times 27 May 1985Major cyclones in the history of Bangladesh https://www.dhakatribune.com/bangladesh/2021/05/24/major-cyclones-in-the-history-of-bangladesh Dhaka Tribune 24 May 2021https://reliefweb.int/report/bangladesh/bangladesh-cyclone-may-1985-undro-situation-reports-1-10 Bangladesh - Cyclone May 1985 UNDRO Situation Reports 1-10 - Bangladesh
