The Dhaka Profile and Earthquake Risk Atlas is part of the deliverables of the Bangladesh Urban Earthquake Resilience Project (BUERP),a collaboration of the World Bank, EMI, and the Government of Bangladesh. This document is a compilation of physical & socioeconomic profiles, built environment, and earthquake hazards, vulnerability & risks information for Dhaka. showing The visual representations of this information are made straight forward and easy-to-understand by the non-specialist. The document serves as a single reference to find key information about Dhaka and the potential impacts of a Mw7.5 earthquake on the Madhapur Fault which is located about 50 kilometers of the City. The information is intended to be educational first, but to also support science-based earthquake preparedness, response and mitigation planning.
Dhaka, the capital city of Bangladesh, is a fast growing city of more than 14 million people (for the Greater Dhaka) and is prone to many hazards including floods and earthquakes. Bangladesh is the most disaster prone country in the world due to its geographic location and land characteristics. The country endures wide scale flooding and cyclones, droughts, tornadoes, river bank erosions, earthquakes, and tsunamis. Over the past 200 years, several earthquakes have struck Bangladesh measuring between 7.0 and 8.7 on the Richter scale.
The earthquake risk information provided in the Dhaka Profile and Earthquake Risk Atlas is based on the results and findings of the Hazards, Vulnerability and Risk Assessment (HVRA) component of the BUERP. The HVRA provides an understanding of the impact of earthquakes in Dhaka City, including estimating the severity of ground motion, ground failure and consequent physical and socio-economic losses.
The maps, charts, figures, and other data visualizations in this atlas are based on various datasets shared to the BUERP by the Rajdhani Unnayan Katripakhaya (RAJUK), Bangladesh Bureau of Statistics Census of 2011, and Dhaka South City Corporation (DSCC). The original datasets were only modified in that the study area was extracted from a larger data set which is the Dhaka Metropolitan Development (DMDP) Area. No other modifications were made to the data. The earthquake exposure datasets, including some of the hazard and vulnerability information used to develop the risk information (i.e. estimates of potential damage and loss) came from the reports and scientific studies published by CDMP, a project of the Ministry of Disaster Management and Relief of Bangladesh. For the purposes of BUERP, these datasets were analyzed using HazUS, CAPRA GIS and CRISIS2007 software packages to determine the potential damages and losses. The earthquake scenario was a postulated 7.5Mw earthquake on the Madhupur Fault. The 7.5Mw Madhupur Fault earthquake scenario was chosen among other scenarios due to its potential to deal the worst possible damage to Dhaka. Damage impact assessments and projections provided in this study are meant to inform various stakeholders as well as the population of Dhaka on the hazards, vulnerabilities, and risks caused by earthquakes so that they can improve their planning and policy making processes, and be better prepared and informed.
The Dhaka Profile and Earthquake Risk Atlas aims to help in providing essential scientific data and information to improve capacity for earthquake resilience of Bangladesh. The outline of the Dhaka Profile and Earthquake Risk Atlas presented below provides the details on the exposure data and outputs from the earthquake risk assessments.
The readers of this document will be informed about the earthquake hazard, identify physical and socio-economic vulnerabilities and acquire better knowledge of the earthquake risks to Dhaka. The Dhaka Profile and Earthquake Risk Atlas would be able to provide technical and scientific information for the formulation of risk reduction and management strategies and plans. It could also provide foundation for policy making and planning for risk sensitive growth and development. This information could be utilized to improve institutional and community capacity for urban resilience. It could also provide foundation for policy making and planning for risk sensitive growth and development.
