this book review presents the merits and drawbacks of engineering geology for underground works edited by gattinoni et al. and published by springer in 2014. this book summarizes most of the problems an engineer may encounter in underground design, construction and operation.this book is useful for students and professionals in engineering geology and is also referable for scholars in relevant ...
In recent decades, classical survey techniques (i [...]
On 12 May 2008, the 8.0-magnitude Wenchuan earthquake occurred in Sichuan Province, China, triggering thousands of landslides, debris flows, and barrier lakes, leading to a substantial loss of life and damage to the local environment and infrastructure. This study aimed to monitor the status of geologic hazards and vegetation recovery in a post-earthquake disaster area using high-resolution aer...

Geologic maps are foundational products for natural hazard assessments but developing them submarine areas is challenging due to a lack of physical access the study area. In response, geomorphologic used provide geologic context and spatial information on landforms related geo-hazards risk management. These generated from remotely sensed data, e.g. digital elevation models (DEMs), which introdu...
According to the field investigation data, a meteorological forecast and alarm model of geologic disasters in Hefei Area has been established. This model was based on GIS raster data model in order to be integrated with GIS Digital Terrain Model (DTM) Component Object Model (COM). Some important factors that put premium on geological hazards, such as intraday and five-day forecasting and limina...
The California Seismic Hazards Mapping Act of 1990 directs the California Geological Survey (CGS) to delineate seismic hazard zones of required investigation for earthquake-induced ground failures specifically, liquefaction and seismically triggered landslides. To date, more than 100 official Seismic Hazard Zone maps have been released, covering 200 cities and unincorporated areas in ten counti...
