  • 1. Earthquake engineering is a multidisciplinary field that incorporates aspects of geotechnical engineering, structural engineering, seismology, and other disciplines to study the behavior of structures and buildings during earthquakes. The goal of earthquake engineering is to design structures that can withstand the powerful forces generated by seismic activity, reducing the risk of damage and collapse. Engineers use advanced analysis techniques, computer simulations, and physical testing to assess the vulnerability of buildings and infrastructure to earthquakes, and to develop cost-effective solutions to improve their resilience. Earthquake engineering plays a crucial role in ensuring the safety of buildings and communities in seismic regions, helping to save lives and mitigate the impact of natural disasters.
