Seismic vulnerability assessment through RVS for critical infrastructure and commercial built-ups along the national highway 109 in Haldwani, Uttarakhand, India

Author(s): Kritika Bora, Ravindra K Pande
Abstract: Entire Himalayan terrain is recognized as being highly prone to intense seismic activity and in the past, the region has been jolted by four great Earthquakes (Magnitude >8 on Richter scale); Shillong (1897), Kangra (1905), Bihar-Nepal boarder (1934), and Assam (1950) apart from Kumaun earthquake (1720) and Garhwal earthquake (1830). The presence of major thrusts like Main Central Thrust (MCT), Main Boundary Thrust (MBT), Main Frontal Fault (MFF) and Himalayan Frontal Fault (HFF) along with innumerable structural discontinuities like faults, lineaments etc have made the region more vulnerable to seismic activity. As a newly formed state, Uttarakhand has witnessed rapid growth in urban areas. The result of rapid growth of urban areas has led to unplanned growth of towns and cities. Negligence to the skilled construction practices due enormous concentration of population has led to a boom in unsafe infrastructure. With every city growth comes also the growth of critical infrastructure and commercial centers. CIs include a range of engineered systems, assets and facilities which are essential for day-to-day societal functions, as well as continued economic and societal functioning in the aftermath of a disaster event. Therefore, while assessing the vulnerability of housing in newly developing cities one should also need to assess the critical infrastructure like transport and communication, so that the worst-case scenario if a disaster struck could be mitigated. Also, the commercial centers along the national highway which are of economic importance can be assessed for seismic vulnerability.
