RAINFALL INDUCED HAZARDS ANALYSIS OF MIZORAM
Rainfall induced hazards analysis was done for the state of Mizoram. These hazards include landslides, floods, cyclones, hailstorms and storms which greatly affects the state and had a detrimental effect on its economy and well-being of its citizens.
Approach/Methodology adopted
Hazards occurrences data (in this case, the number of villages affected) was collected from Department of Disaster Management & Rehabilitation, Government of Mizoram. Rainfall data was obtained from State Meteorological Centre, Directorate of Science & Technology, Government of Mizoram.
The main basic approach in this study is based on statistical analysis which involves regression analysis to estimate or predict the nature (+ve or -ve) and magnitude of the relationship amongst the hazard occurrence (number of villages affected) and rainfall. Rainfall anomaly index was also employed to determine extreme rainy years and rainfall deficit years.
Significant results brought out as a part of the project
The analysis reveals that there exists strong positive corelation amongst the hazard occurrence (number of villages affected) and rainfall. It shows that most hazards occurrences are induced by heavy rains especially landslides and floods amidst other factors in play. These results of the analysis were compiled and published in a booklet form entitled “Rainfall induced hazards analysis of Mizoram” on 28th October 2020.
