Bangladesh, the most vulnerable country in the world to the impact of natural disasters is also a leader in emergency preparedness and disaster response, particularly for cyclones, tidal surges and floods. This was achieved through 25 years of effort, which was catalyzed through two devastating cyclones, one in 1970 and 1991 that caused the deaths of approximately 500,000 and 300,000 people respectively. Part of what makes Bangladesh so strong at cyclone preparedness and response is the fact that major cyclones seem to hit Bangladesh every 3-4 years. Recurrence of this frequency is quite unique.
On the other hand, major seismic events that lead to major losses occur infrequently. Cities like Dhaka and Kathmandu, which are susceptible to major earthquakes, haven’t experienced a major shake in more than a generation. Unfortunately, a lack of frequency often leads to complacency amongst governments and citizens. Even more problematic is the very rapid accumulation of assets and population in urban environments in South Asia, including Dhaka.
Walking through the streets of Dhaka paints a picture of a city with significant structural vulnerabilities – where poor construction standards, lack of enforcement, and poor maintenance turn many buildings into potential hazards. When a building in Savar collapsed in April 2013 – killing over 1,100 people and injuring thousands more – it was a wakeup call for Bangladesh. The collapse was not triggered by an earthquake, it was the result of catastrophic structural failures, but it was a glimpse into what could happen in the event of a major earthquake.
