What is it about?
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.

Why is it important?
Review 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
Perspectives
This article is written in very simple language and presented the risk cause of potential earthquakes in Bangladesh and its surroundings. This can be used by the researcher as a reference to consider the maximum designed earthquake need to consider for a seismic resilient building. Also, the policymakers can use it for risk mitigation plan development.
