Structural analysis of S-wave seismics around an urban sinkhole; evidence of enhanced subrosion in a strike-slip fault zone

Abstract

Abstract. In November 2010, a large sinkhole opened up in the urban area of Schmalkalden, Germany. To determine the key factors which benefited the development of this collapse structure and therefore the subrosion, we carried out several shear wave reflection seismic profiles around the sinkhole. In the seismic sections we see evidence of the Mesozoic tectonic movement, in the form of a NW–SE striking, dextral strike-slip fault, known as the Heßleser Fault, which faulted and fractured the subsurface below the town. The strike-slip faulting created a zone of small blocks (

“…Sinkhole subsidence and collapse 30 cause substantial economic and human losses globally (Frumkin and Raz, 2001;Wadas, 2017; 31 Closson, 2005). In Italy, a total of 750 sinkholes have been identified by Caramanna et al (2008).…”
