A novel GIS based seismic hazard assessment in Odisha, India

© 2018 Proceedings - 39th Asian Conference on Remote Sensing: Remote Sensing Enabling Prosperity, ACRS 2018 This research was conducted to analyse and estimate the PGA (Peak Ground Acceleration) and seismic amplification of Odisha state in India by using earthquake events recorded by USGS (US geological survey) of the region from the year 1950 to 2015. The analysis also includes for an approximately a range of 300 km from every side of state. Many attempts have been proposed to investigate the PGA in this region during the last decades. Therefore, it was a requirement to implement various methods using some recent viewpoints and methodological approaches. Furthermore, research approaches on seismic hazard analysis need to be updated for currently experienced seismic events. Therefore, the objectives of this research focusing; 1) to ensemble various attributes of seismic events for graphical investigation and, 2) to prepare hazard maps using PGA based on a distinctive GIS approach. Our results clearly showed that the region of Odisha is seismically active and there exists the hazard of ground shaking. It also provides a very accurate evaluation of seismic hazards including the seismic waves that influences surface of the ground based on the amplification map. These findings can be considered for the rapid improvement in earthquake research during recent decades that attempts to study seismic hazards and risks in Odisha
