Abstract

The purpose of this paper is to present an integrative review of the literature to understand the underlying risks of tectonic plate movements, earthquakes and possible earth tremors on Bangladesh as a country filled with waterways.Design/methodology/approachThis study presents a review of seismic activities to present an overview of the active tectonic architecture of the region and its seismic potential with past consequence in Bangladesh region and its immediate surroundings. For the purpose of this review, peer-reviewed journals and electronic databases are the main sources for identifying studies, along with conference proceedings from the similar events and networks.FindingsReview reveals that Bangladesh sits on three tectonic plates atop the world’s largest river delta and has blind faults, shallow faults and high amplified liquefiable zones. It has experienced few devastating earthquakes but most of the records are not documented and also a lack of proper seismic equipment could not record all the events. Also Bangladesh is ill prepared to tackle the aftermath of any strong earthquake and if an earthquake with 7 Mw or greater magnitude occurred, it would leave Bangladesh blighted by a catastrophic disaster with significant destruction of infrastructure, fire outbreaks resulting from breakdown of gas piping systems, fire from collapsed electrical lines and disruption of water connections both in urban and rural centres with greater impact on industrial cities that may not have adhered to standard building codes.Originality/valueThis paper outlined the necessity of an earthquake hazard catalogue, also preparation in sense of seismic risk mitigation and influence of decision-makers, policy institutes and professionals in ensuring infrastructure development and the building code provides for a safe environment and resilient buildings that can reduce or eliminate the risks.
