<p>Lightning, one of nature’s most powerful forces, poses a significant threat to lives and livelihoods throughout India. Bihar, in particular, experiences a high frequency of lightning strikes, with rural communities bearing the greatest impact. Despite the severity of this hazard, research on lightning patterns and casualty trends remains limited. This study aims to bridge that gap by analysing lightning flash density and associated casualties in Bihar from 2019 to 2024. The analysis is based on high-resolution data from the Lightning Location Network (LLN) of the Indian Institute of Tropical Meteorology (IITM) and the India Meteorological Department (IMD), alongside real-time casualty records from the Disaster Management Department, Government of Bihar. A detailed spatiotemporal analysis reveals distinct seasonal trends, with lightning activity peaking between May and September. The highest flash densities are recorded in the southern and eastern regions of Bihar, whereas the northern districts experience relatively fewer strikes. Cluster analysis indicates a steady rise in lightning occurrences from March to July, with peak strikes occurring in the late afternoon and early evening hours. Beyond the statistics lies a stark human toll. Rural populations remain vulnerable due to prolonged outdoor exposure and a lack of protective infrastructure. Alarmingly, over 72% of lightning-related casualties involve males, particularly farmers and teenage cattle herders, whose daily activities put them at heightened risk. These findings point to the need for targeted interventions, including advanced early warning systems, widespread public awareness initiatives, and the implementation of robust lightning protection measures to reduce fatalities in high-risk regions. While lightning is an unstoppable natural phenomenon, it’s devastating impact can be mitigated through knowledge, preparedness, and proactive action.</p>
