**1. Introduction**

Over recent years, there has been an explosive growth of interest in the development of novel gel-phase materials based on small molecules. The occurrence of a major earthquake event is still seen as a catastrophe, with devastating consequences over human lives, buildings, and transportation networks, causing a large-scale impact on any society. Indeed, even if becoming particularly devastating to poor, underdeveloped countries, it equally affects populations and several infrastructures in modern, industrialized countries. For global picture, the occurrence of earthquakes can have an outcome, which is reflected in the deep changes in building philosophy or large

investments in seismic design strategies. A number of recent earthquakes are typically referred to not due to only their destructive impact but also owing to the lessons that have been learned, leading, and sometimes to reflect changes or the establishment of turning points in seismic design philosophies. Chhattisgarh (21°17<sup>0</sup> 42.47″ N, 81° 49<sup>0</sup> 41.630 E) is a newly developed state in India. North Chhattisgarh is rich in temples, natural beauty, dense forests, hill stations, water bodies, and industries. The northern portion of the state includes major districts that are Ambikapur, Baikunthpur [Koria], Korba, and Jashpurnagar. India's National Center for Seismology (NCS) and USGS reported a magnitude 4.8 earthquake near Ambikāpur, Surguja district of Chhattisgarh, in the morning on Monday, July 11th, 2022, at a moderately shallow depth. On the same date, earthquake of magnitude 4.3 is reported near Korba district. Further on an earthquake of magnitude of 4.6 on 29 July 2022 is reported by National Center for Seismology, near Baikunthpur [Koria]. Recent seismic activity around the districts of north Chhattisgarh is increased. It is essential that the current study is focused on the seismic vulnerability analysis over the major district headquarters of the north Chhattisgarh region.
