Flooding risk is a real problem in Vietnam leading the population to build dykes. When focusing on Hanoi and its surrounding, the flooding risk is even higher than in other parts of the country as most of areas in and around Hanoi are below the level of the river. In this framework, subsidence phenomenon which is the result of ground water pumping, is considered critical because of its close re...

This article presents a classification tree with predictive and prescriptive capabilities for the management of ground fractures in crowded suburb Tláhuac, municipality Mexico City. The is trained observations parametrized basic geotechnical geological variables specifications urban environment where they manifest. With tree, complexity scenario affected by subsidence phenomenon cleared because...

In March 1996 an intense swarm of volcano-tectonic earthquakes (-3000 felt by local residents, A/max5.1, cumulative moment of 2.7 x 10 •8 N m) beneath Akutan Island in the Aleutian volcanic arc, Alaska, produced extensive ground cracks but no eruption of Akutan volcano. Synthetic aperture radar interferograms that span the time of the swarm reveal complex island-wide deformation: the western pa...

Compared to opencut mining, underground coal mining is more common in Australia due to its lesser impact on the environment. Although there are several underground mining methods, such as the longwall, pillar, bord, and miniwall, longwall mining is the most commonly used method due to its high efficiency. However, longwall mining does lead to significant ground subsidence. Mining subsidence is ...

China is the world’s largest coal-producing country and mining-related land subsidence happens almost in every coal mining area. In north-west China, land subsidence in coal mining areas is mainly caused by underground mining activities and uncontrolled burnings of subsurface coal seam. As Hoffmann (2004) reported, burning coal-seams can result in extensive subsidence of several meters and typi...

The accurate detection of land subsidence rates in urban areas is important to identify damage-prone areas and provide decision-makers with useful information. Meanwhile, no precise measurements of land subsidence have been undertaken within the coastal Port-Said City in Egypt to evaluate its hazard in relationship to sea-level rise. In order to address this shortcoming, this work introduces an...
