Abstract

This study employed geophysical surveys at 242 locations across the Jammu Region to assess dynamic soil properties and Double Resonance Effect (DRE). This approach facilitated measurements of Resonance Frequency (f₀), H/V Amplitude (

A

), Spectral Shape, and Average Shear Wave Velocity at 30 m depth (

V_{s 30}

), leading to the identification of risk zones. The study categorized sites into distinct resonance classes and provided a comprehensive database for engineers and consultants. Key findings included the identification of high DRE risk areas for earthquake-resilient construction. Additionally, it will help in assessing liquefaction potential and predicting settlement. This study aligns with UN's Sustainable Development Goals 9 and 11 by promoting resilient infrastructure and enhancing urban safety and sustainability through improved construction practices and disaster preparedness in the Himalayas.

将MHVSR和MSOR技术与JFIM相结合，对西北喜马拉雅地区查谟和克什米尔地区的场地和建筑物进行地震易损性评估

在查谟地区的242个地点进行了地球物理调查，评估了土壤的动态特性和双共振效应。这种方法有助于测量30米深度的共振频率（f0）、H/V振幅(A)、频谱形状和平均横波速度（Vs30），从而识别危险区域。该研究将场地划分为不同的共振类，并为工程师和顾问提供了全面的数据库。主要发现包括确定DRE高风险地区进行抗震建设。此外，它将有助于评估液化潜力和预测沉降。本研究与联合国可持续发展目标9和11相一致，通过改善喜马拉雅地区的建筑实践和备灾，促进有韧性的基础设施建设，加强城市安全和可持续性。

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
