A Case Study for Lightning Scenario and Awareness Building in Bangladesh

Lightning frequencies have increased recently to an alarming way during the monsoon and summer periods in Bangladesh. As a result it has to accept an annual average death toll of 200-300 people from the lethal lightning strikes in the last decade. Observing the consequences of these lightning causalities, it has been considered as one of the natural disasters since 2016. A secondary data sources have been applied in this study. From observations it found that the northeast regions are mostly affected and farmers and fishermen are the most vulnerable groups to lightning fatalities. The aim of this research to introduce a conceptual model to build lightning awareness to combat lightning fatalities in Bangladesh. This policymakers of Bangladesh could think seriously how to implement this lightning awareness building effectively diminishing the enormous causalities.

Spatial Vulnerability Assessment of Extreme Lightning Events in Bangladesh Using GIS

This study explores human death, injury and overall casualties as a result of ongoing extreme lightning events in Bangladesh. Especially the month of May starting from 2010 to mid-2017 were taken under consideration for this study where, a total of 1811 lightning casualties composed of 339 fatalities and 273 injuries are identified. Spatial and geographic aspects of division wise lightning events are evaluated with the help of ArcGIS.

One seventh of death people are affected during stay in indoor like-house, mosque etc. The rural people affected by lightning fatalities accounted 93%. The analysis shows that the highest lightning vulnerable zone is Sunamganj, Sylhet.J. Environ. Sci. & Natural Resources, 10(2): 11-18 2017
