The northeastern region of India is prone to frequent seismic activity due to the dynamic geological processes occurring there. The convergence of the Indian Plate with the Eurasian Plate leads to the formation of numerous mountain ranges, including the Himalayas, Naga Hills, Shillong-Karbi Massifs, and the Assam Valley. These geological features are characterized by crustal-scale active faults that accumulate stress over time, often resulting in moderate to large earthquakes when released. The study focuses on a significant earthquake event with a magnitude of Mw 6.4 that occurred near the Kopili Fault and Himalayan Frontal Thrust in the eastern Himalayan foreland region on April 28, 2021. The epicenter was situated around Dhekiyajuli in the Sonitpur District of Assam, India. The study explores the environmental impacts associated with the earthquake. PACT, created by the Federal Emergency Management Agency (FEMA) of the United States, stands for “Probabilistic Assessment for Consequences and Treatment” of earthquake risk. It is an electronic tool designed to assess the potential future losses resulting from earthquakes, considering various factors such as casualties, building repair or rebuilding costs, recovery time, and the probability of needing hazardous placards. The development of PACT was influenced by the performance-based seismic engineering framework established by the Pacific Earthquake Engineering Research Center (PEER). By integrating probabilistic methods and engineering principles, PACT provides valuable insights into the potential consequences of earthquakes, helping decision-makers prioritize mitigation and preparedness efforts. It allows for the evaluation of different scenarios and the assessment of the effectiveness of various risk reduction strategies. Overall, PACT serves as a valuable tool for enhancing earthquake resilience by enabling informed decision-making and resource allocation to mitigate the impacts of seismic events.
