<p>High-resolution airborne LiDAR and field mapping were used to investigate a 29 km-long section of the Hurunui segment of the Hope Fault concealed beneath beech forest. Approximately 20 km of the dextral strike-slip principal slip zone (PSZ) was identified ...

<p>Analysis of light detection and ranging (lidar) derived topography combined with field data enables measurement of small (&lt;30 m), previously unrecognized dextral offsets beneath dense temperate rainforest along New Zealand&rsquo;s central Alpine fault. ...

Terrestrial Laser Scanner has been used to detect rock falls which have occurred in a limestone cliff during some years, in the difficult configuration of the Subalpine Chains. In a rock wall of width 750m and height 200 m, 130 rock falls larger than 0.1 ...

Three dimensional laser scanning, also known as Light Detection and Ranging (LiDAR) has quickly been expanding in its applications in the field of geological engineering due to its ability to rapidly acquire highly accurate three dimensional positional data. ...

Rock falls from cliffs and other steep slopes present numerous challenges for detailed geological characterization. In steep terrain, rock-fall source areas are both dangerous and difficult to access, severely limiting the ability to make detailed structural ...

We analyzed a combination of airborne and terrestrial LiDAR, high-resolution photography, seismic, and acoustic data in order to gain insights into the initiation, dynamics, and talus deposition of a complex rock fall. A large (46 700 m³) rock fall ...

Yosemite Valley has experienced over 600 rock falls since 1850, but determining the exact source areas, volumes, and failure mechanisms for these rock falls has previously been difficult because of a lack of comprehensive imagery of the cliff faces. We obtained ...

Landslides are a recurring problem on hillslopes throughout the Puget Lowland, Washington, but can be difficult to identify in the densely forested terrain. However, digital terrain models of the bare-earth surface derived from LIght Detection And Ranging ...

A factor limiting preliminary rockfall hazard mapping at regional scale is often the lack of knowledge of potential source areas. Nowadays, high resolution topographic data (LiDAR) can account for realistic landscape details even at large scale. With such ...

In nearly 240 years 53 landslides have occurred along the Quebec City Promontory, causing 88 fatalities mainly by rockfalls. In October 2004 a rockfall reached the road close to the 1889 rockfall event which killed 35 people and injured 30 others. Using a ...
