This project focused on quick clay or rapid earth flow landslides in Sweden. These landslides are not particularly constrained to steep slopes and have been known to slides even in low-to-moderate angle slopes. Undisturbed quick clay resembles a water-saturated gel. When a mass of quick clay undergoes sufficient stress, it instantly turns into a flowing ooze, a process known as liquefaction.
The goal of the project was to install a permanent monitoring and early warning system to track the evolution of the Maca landslides, located in a high seismicity region (next to Arequipa, Peru). The landslides threatens a village of 900 inhabitants, a very popular and frequented road (500,000 vehicles/year), and pre-Inca terraces, and is subject to rapid acceleration due either to the high seismicity of the area or to periods of intense rainfalls.
This project came about after the southern Indian state, Kerala, experienced >140% rain than normal, during 1-20 August 2018. >1 million people were displaced, 483 were declared dead, and over 1300 landslides affected bridges and roads cutting off towns, villages, and communities’ livelihoods. The main objective of this project is to improve landslide hazard analysis in the district of Idukki, Kerala by using applied geoscience techniques such as Electric Resistivity Survey (ERS), rain gauge network
Geophysics applied to geotechnical study in Ouro Preto, MG – Brazil This project aims to establish and implement a methodology for assessing and classifying geotechnical risky areas in urban centers using non-invasive and low-cost technology approach by using drone, magnetometer, susceptibility meter, spectrometer and electro resistivity meter to directly benefit approximately 48,150 locals and 500,000 tourists, who visit the historic city of Ouro Preto annually, and provide geotechnical analysis utilizing non-invasive geophysics that can be
Each year during the rainy season, residesnts of slums and hillsides in Brazil are put on alert as landslides, floods, and outbreaks of leptospirosis occur. This multi-disciplinary project brought together geophysical, civil engineering, and meteorological data to study, classify, and monitor areas that pose a high risk of landslides in the Rio de Janeiro state of Brazil. Awareness and emergency preparedness training was conducted with local residesnts and geohazards detection systems were installed.
The torrential rainfall in the Balkan region in May of 2014 caused extensive flood damage and thousands of landslides devastating roads, bridges, buildings, and other infrastructure. Current scientific information about the subsurface is essential in reconstruction efforts. Field surveys were conducted to provides detailed geotechnical assessments to reconstruction authorities, and community members are participating in the project.
