Short summary
This research demonstrates impressively, what has been possible by counting with a variety of variables and data sets in order to model landslides in a mega-vulnerable city, in this case Quito in Ecuador. Furthermore, we also compared the previously existing map of landslides in the city based on the current municipality with our new map, which allows an improved, high-resolution view of the potential and most vulnerable sites and zones.

Any sinkhole occurring in a highly active city provokes chaos and disturbance. In the city of Quito a big sinkhole appeared in a critical road interchange called El Trébol. For a few months the city came close to collapse with its traffic in this zone and a state of emergency was declared. During the recovery and reconstruction of the site, the cause was able to be determined as the combined negligence of monitoring of older subterranean infrastructure as well as high precipitation.

Short summary
Subsidence damage in Mexico City and risks for urban infrastructure and inhabitants have important mitigation costs. In this work, we develop a methodology for the estimation of physical vulnerability of the geological media to fracture. Factors conditioning the localization of deformation are analyzed using a deterministic approach. Physical variables were mapped, measured and integrated into a database to estimate a vulnerability index to fracturing (VIF), useful for decision making.

This work reports results of experiments made in analogue materials reproducing the occurrence and propagation of fractures associated with land subsidence driven by groundwater pumping. We compare the physical experimental model results with a numerical model that tests the development of stresses above a bedrock ridge that forms the base of an aquifer.

Short summary
The stress variation induced by overdraft of aquifers in sedimentary basins may cause ground rupture in the form of activation of pre-existing faults or earth fissure generation. The process is severely threatening many areas in China and Mexico. Ruptures yield discontinuity in the displacement and stress fields that classic finite element (FE) models cannot address. We proved how Lagrangian approach provides more stable solutions than Penalty approach.

We present a series of physical experiments that examine with detail the evolution of subsidence in a volcanic maar crater, located in central Mexico. The crater is thought to be connected to the adjacent aquifer, which has been extensively exploited during the last 35 years. Subsidence in the sediments filling the crater show deformation manifested as ring faults and fractures. The results may be relevant to understand the evolution of subsidence in similar volcanic settings elsewhere.

Short summary
An analysis of the deformation conditions of lacustrine materials deposited in the volcanic valley of the Mexico City is presented. Currently geotechnical studies assume that compressibility of granular materials decreases in depth due to the lithostatic load. Our results show that Cc for fine grain materials (lacustrine) can be vertically variable, particularly when soils and sediments are the product of different volcanic materials. These variations need to be considered when modelling LS.

Short summary
In the eastern sector of Mexico City the sub soil consists of high contrasting sequences (lacustrine and volcanic inter bedded deposits) that favor the development of erratic fracturing in the surface. The results of applying the GPR, MASW and SR methods simultaneously show the persistence of the clayey lacustrine material with variable thickness encased by volcanic materials. The contrasting mechanical properties between the two types of material may cause slippage over lithological contacts.

Short summary
Sinkholes in any areas may result deadly or costly. A sinkhole happen to be in a highly trafficked area in Quito, Ecuador. Besides the problems and additional costs of repair, we have found out during our study, that the costs of the people who had to pass this area had to pay much more than the "simple" reconstruction costs. A critical look on historic sinkholes in the central part of the city of Quito, allowed us to identify even huger problems to come in important areas of Quito.
