Investigation of urban earthquake disaster shelter and relief base in Bangladesh

Bangladesh is a south Asian developing country which is used to struggle with various natural disasters and the earthquake is one of them. Bangladesh is of the most earthquake venerable countries of the world^[1] but Bangladesh is ill prepared to tackle the aftermath of any strong earthquake.  Geographical location of Bangladesh makes it ideally suited to earthquake. Bangladesh is surrounded by the regions of high seismicity which include the Himalayan Arc and shillong plateau in the north, the Burmese Arc, Arakan Yoma anticlinorium in the east and complex Naga-Disang-Jaflong thrust zones in the northeast.^[2] It is also the site of the Dauki Fault system along with numerous subsurface active faults and a flexure zone called Hinge Zone.[2] These weak regions are believed to provide the necessary zones for movements within the basin area. Bangladesh is the world’s most densely populated area, any future earthquake shall affect more people per unit area than any other seismically active regions of the world. Here I have tried to discuss about the risks of earthquake disaster in Bangladesh and the historical earthquakes that occurred in Bangladesh.
