Undoubtedly Bangladesh is one of the most earthquake prone countries in the world. Cities like Dhaka, Chittagong, Sylhet, Rangpur, Mymenshing & Cox’s Bazar may be considered most vulnerable to seismic hazard. Specifically, Dhaka is one of the most vulnerable mega-city in the world. Since earthquake is not very frequent in our country like Japan, USA or China we are not aware and prepared as we are for flood and cyclone. An infrequent and forgettable hazard causes severest damage. That is why we have to be very careful about the earthquake risk mitigation and response mechanism.
Common concept of disaster risk reduction has three components- prevention, mitigation and preparedness. Since prevention of earthquake hazard is beyond the capacity of human being we can simplify the concept of earthquake risk reduction by mitigation and preparedness. As on response the concept may be immediate search & rescue, emergency management followed by short and long term rehabilitation, reconstruction and redevelopment. To act timely we have to be prepared in an organized and disciplined manner. Therefore we have no way but to have earthquake disaster management plan at all level as an annex/enclosure to National Disaster Management Plan which we are going to have within a very short period.
Earthquake Disaster Management Plan should have two parts – one is earthquake risk mitigation plan and the other is earthquake response/contingency plan. There shall be one national level plan and local level plan for each community (e.g. ward level of city corp.) and each organizations/institutions such as Armed Forces Division(AFD), City Corporation, City Development Authority, Fire Service & Civil Defense Department, Water, Power & Gas Supply Authority, Public Works Department(PWD) and so on. Culture shall have to be developed for continuous sharing and updating such plans to get optimum results. Plans should address all the associated elements and it must be lucid and implementable rather than a shelf material.
Here we can cite guideline for key contents and/or functions of Earthquake Disaster Management Plan.
For Earthquake Risk Mitigation Plan:
The plan should address four major areas of earthquake risk reduction:
- Defining the earthquake hazard
- Learning about earthquake hazards, preparedness, and risk mitigation
- Planning and building for earthquakes
- Living with earthquakes
Defining earthquake hazards should be addressed in the Geo-science section which includes mapping faults, characterizing the size and occurrence of earthquakes along faults, and expanding the seismic station network. Earthquake awareness and education is the major focus of communicating earthquake hazards, preparedness for earthquakes, and earthquake risk mitigation to citizens, professionals, and decision makers. Part of the strategy of this task should be in the Schools Earthquake Awareness Program. In making a more seismically resistant built environment, the plan addresses issues of land use and improvements for existing buildings and new construction, including the mitigation of nonstructural hazards, and utilities and transportation. For living with earthquakes, the plan includes the enhancement of earthquake preparedness, emergency response, and recovery from an earthquake disaster.

For Earthquake Response Plan:
Response Requirements:
In the event of a damaging earthquake, a large number of response requirements will be needed for effective coordination and response of all agencies at all levels of government and in the private sector. In light of this a functional organization for response will be used to guide the process. This will identify, define and assign responsibilities to lead and support agencies within the plan. The emergency response functions are assigned to primary and supporting agencies that would have that responsibility within the plan.
Key issues to address:
Search and Heavy Rescue
Health Service & Welfare
Request for External assistance for search and rescue
Law Enforcement & Security
Emergency Shelter & Mass Care
Fire-fighting/Rescue
Communications
Damage Assessment
Identification Care & Disposal of Dead
Hazardous Material Response
