The subsidence reported from the Rainawari, 4 kms north west of Lal Chowk (The city centre of Srinagar) in 1999–2000 was mainly restricted to Surateng (which in local language means a mound of ash) locality of the area. Rainawari, 4 km north west of Srinagar city invariably witnessed land subsidence for the past several decades and in this process most of the structures in the area suffered massive damage including collapse, sags, sinking of floors, temporal and spatial evolution of cracks, swaying, sink holes, colloquially numerous structures started sinking and tilting and major potholes appeared on roadways, thus creating panic in the inhabitants of the area. The surface change phenomena in the present study is strictly restricted to a small area, where extensive underground mining related to pottery industry has a history of hundreds of years. In this context, six ground penetrating radar profiles have been acquired from two main sites namely JLNM hospital and Surteng locality of Rainawari using 200, 500 MHz shielded and 100 MHz rough terrain antennas. In order to investigate the shallow sub-surface, possible locations of sink holes, kinematics of the subsidence phenomena, spatial-temporal evolution of sink holes, effects of subsidence on surface structures, to locate underground caves and cavities, seismic liquefaction features, geometry and trends in near surface tectonic deformation, geotechnical characterization and seismic resilience of the surface structures, the subsurface imaging was acquired using GPR. Major sub-surface observations made were underground cavities, room and pillar mining structures and voids. In addition to the sub-surface structures caused by the mining in the historical past, the surface deformations were observed in the form of cracks developed in the construction.

1999 年至 2000 年间，位于 Lal Chowk（斯利那加市中心）西北 4 公里处的 Rainawari 报告的沉降主要限于该地区的 Surateng（在当地语言中意为一堆灰烬）地区。斯利那加市西北 4 公里处的 Rainawari 在过去的几十年里不断发生地面沉降，在这个过程中，该地区的大部分结构遭受了巨大的破坏，包括倒塌、下陷、地板下沉、裂缝的时空演变、摇摆、下沉孔，通俗地说，许多结构开始下沉和倾斜，道路上出现了主要的坑洼，从而在该地区的居民中造成了恐慌。本研究中的地表变化现象仅限于一小块区域，该区域与陶器工业相关的大规模地下开采已有数百年的历史。在这种情况下，使用 200、500 MHz 屏蔽和 100 MHz 粗糙地形天线从两个主要站点（即 JLNM 医院和 Rainawari 的 Surteng 地区）获取了六个探地雷达剖面。为了研究浅表层、下沉孔的可能位置、下沉现象的运动学、下沉孔的时空演化、下沉对地表结构的影响、定位地下洞穴和空洞、地震液化特征、几何和为了了解近地表构造变形、岩土特征和地表结构的地震弹性的趋势，使用 GPR 获取地下成像。进行的主要地下观测是地下洞穴、房柱式采矿结构和空隙。
