“…Such discrepancy is probably due to the presence of different lithology, which has different subsidence potentials [50,51], or because the groundwater depletion is uneven, thus it does not affect the east side of CG. Moreover, the presence of buried faults, which act as a barrier to groundwater flow, may produce differential subsidence [45], but such feature is not introduced in our model because of the lack of field data.…”

Land subsidence, Ground Fissures and Buried Faults: InSAR Monitoring of Ciudad Guzmán (Jalisco, Mexico)

Abstract:We study land subsidence processes and the associated ground fissuring, affecting an active graben filled by thick unconsolidated deposits by means of InSAR techniques and fieldwork. On 21 September 2012, Ciudad Guzmán (Jalisco, Mexico) was struck by ground fissures of about 1.5 km of length, causing the deformation of the roads and the propagation of fissures in adjacent buildings. The field survey showed that fissures alignment is coincident with the escarpments produced on 19 September 1985, when a strong earthquake with magnitude 8.1 struck central Mexico. In order to detect and map the spatio-temporal features of the processes that led to the 2012 ground fissures, we applied InSAR multitemporal techniques to process ENVISAT-ASAR and RADARSAT-2 satellite SAR images acquired between 2003 and 2012. We detect up to 20 mm/year of subsidence of the northwestern part of Ciudad Guzmán. These incremental movements are consistent with the OPEN ACCESS Remote Sens. 2015, 7 8611 ground fissures observed in 2012. Based on interferometric results, field data and 2D numerical model, we suggest that ground deformations and fissuring are due to the presence of areal subsidence correlated with variable sediment thickness and differential compaction, partly driven by the exploitation of the aquifers and controlled by the distribution and position of buried faults.

“…Land subsidence consists of collapse or settlement of the surface level that may occur due to some reasons such as the dissolution of subsurface formations, sediment compression [1], loading, drainage, vibration, subsurface mechanical erosion, shrinkage of clay soils, tectonic subsidence, and etc. [2].…”

Abstract. Land subsidence phenomenon due to human activities and natural factors has been observed in the plains of Fars province, which imposes heavy damage to agricultural lands, rural buildings, and historical monuments. In this paper, after identifying and determining rate of damage in Fars province, Marvdasht plain and its damaged villages have been chosen as the case study. The land subsidence map of Marvdasht and villages was presented by the data obtained from state of Groundwater, soil, and soil parameters. Also, the e ects of faults, tectonic situation, dried qanat, occurred earthquakes in this area, and the observed ssured were taken into account. Generally, uncontrolled withdrawals from deep drilling wells caused subsidence and extended damage in other areas. Earthquakes intensi ed the damage to rural buildings and contributed to opening gaps. The altered subsidence identi ed in di erent parts of Marvdasht plain and the damage in rural areas along with the predictions made could represent the progressive damage of this phenomenon in the future. Finally, with respect to the climate, geology, land status, characteristic of soil layers, and regional potential, appropriate solutions for the land subsidence prevention and, consequently, reduction of the related damages were presented.

“…Land subsidence subsidence due to groundwater withdrawal is widespread in the Mexican territory in recent decades in valleys where the aquifer consists of unconsolidated material such as alluvial, lacustrine, or volcano-sedimentary deposits geologically recent [1][2][3][4][5][6]. When the aquifer bedrock is irregular, the land subsidence causes faults and fractures on the surface granular fills damaging the existing urban infrastructure [7,8,3].…”

Abstract. The main objective of this research project is to study the application of structural systems based on light gauge cold-formed steel framing to housing in subsidence zones, having the following scopes: characterize the typical settlements in a discontinuity due to subsidence, to build a laboratory facility to simulate these settlements, to simulate and to evaluate numerically and in laboratory in a full scale model the structural performance of a house subjected to settlements due to subsidence, in terms of its stresses and strains and, eventually, its capacity of retrieval to its nondeformed shape.
