1970 Bangladesh Cyclone

In 1970 one of the deadliest cyclones (Bhloa Cyclone) in history hit Bangladesh killing about 500,000 people.  Winds hit 230 mph which resulted in nearby flooding.  The cyclone hit the densely and heavily populated coastal area around the Bay of Bengal, which is one of the poorest places in the world as well.  The resulting waves took out entire villages leaving many homeless.  This hazard I'd say fits the engineering paradigm as well as the developmental paradigm and the behavioural paradigm.  It fits the engineering paradigm because the city didn't have proper infrastructure to sustain both a large cyclone and the resulting flooding due to the poor state of the country.  It also fit the developmental paradigm because Bangladesh is a least developed country so they suffered more because of their lack of wealth for proper infrastructure and with having such a largely populated area with the population being so dense, many people died.  It fits the behavioural paradigm too because the cyclone hit hardest on the low-lying coast of Bangladesh where they had nothing they could do with the 9 meter storm surge and 4 meter rise in tide level, and this wall of water devastated this area of the country.  The low lying islands off the coast experienced the bulk of the destruction.  When looking how the complexity paradigm fits in with this hazard, since it hit in 1970 and it hit an extremely poor country, there wasn't a significant warning issued out resulting in people not being notified that this intense storm was coming and there wasn't a large response team sent out immediately to try to find survivors and rescue them which could have prevented many people from dying.

I go this picture from http://www.tlitb.org/%E2%80%98when-nature-gets-angry%E2%80%99-the-worst-natural-disasters-caused-by-wind/  and just thought it was incredible how large this storm was.
