Despite being classified as low risk seismic hazard zone, the historic and architecturally significant vintage buildings in Vidarbha region are at serious risk of earthquakes, claimed a study. A study titled “Seismic Response Analysis of Vintage Building (Vidarbha Region) Using Building Information Modelling (BIM): A Review” conducted by Prof Divyani Harpal and Vaishnavi Muraskar claimed that Vidarbha has numerous historically significant old buildings which are at serious risk of seismic activities caused by abrupt energy released along fault lines. The world is separated into seismic zones according to geological characteristics and past earthquake activity in order to evaluate and control the danger of earthquakes.

 

The whole world is divided into five seismic zones; that is Zone I to Zone V. Majority of Vidarbha is located in Zone II, a low to moderate seismic zone. Compared to higher seismic zones such as Zones IV and V, this classification suggests a comparatively reduced probability of severe earthquakes. In comparison to other areas of the nation, the eastern Maharashtra region of Vidarbha is situated in a seismically stable location. The Deccan Traps, a sizeable volcanic province that originated about 65 million years ago, has a significant impact on the area. Despite its low seismic activity, Vidarbha has had a few significant earthquakes over the years. Earthquake in Yavatmal in 1997 was a significant one in Vidarbha. Along with this, earthquake in Kamptee in 2024 and again couple of months ago in Kamptee area raised concern for the administration.

 

The study claimed that because of the historical structure’s age and the absence of contemporary engineering methods during construction, these structures frequently encounter difficulties. The integrity and safety of these buildings are seriously threatened by the seismic activity in the area. It is essential to evaluate these historic buildings’ seismic reactivity in light of the possibility of earthquakes in order to guarantee their safety and preservation, claimed the study. The BIM enables comprehensive seismic risk assessment of both structural and non-structural elements as well as detailed 3D modelling. As per the study, the integration of BIM in seismic risk analysis of Vidarbha’s vintage buildings has proven transformative. The BIM analysis highlights the pressing need for retrofitting strategies to safeguard these historically significant buildings. This proactive approach not only preserves the region’s architectural heritage but also enhances the safety of its inhabitants, claimed the study.
