Coastal deposits at Tofino, Ucluelet, and Port Alberni in Vancouver Island along the Cascadia subduction zone were re-examined to improve the earthquake history of the southwest coast of Canada. We found sand sheets interbedded within peat and mud, suggesting deposition by strong flows in a low-energy environment. Based on limiting maximum and mini...

To understand distributions of coastal diatoms along Vancouver Island, British Columbia, Canada, this paper describes diatom assemblages observed in 47 surface sediment samples from intertidal environments. One hundred and eighty‐four diatom taxa were identified from five transects crossing tidal flats, salt marshes, and freshwater forests in Tofin...

The International Consortium on Landslides (ICL) was founded at the UNESCO-Kyoto University joint Symposium in January 2002. The ICL also decided to create the International Programme on Landslide (IPL) and a new international journal Landslides in the foundation meeting in 2002. The ICL was registered as a legal body under Japanese law in 2002 as...
Chapter
Here we describe the development of a novel characterization and monitoring technology for unstable natural and engineered slopes. The system is based on time-lapse electrical resistivity tomography (ERT), which is a geophysical technique used to non-invasively image subsurface resistivity to depths of tens of meters. Resistivity is a useful proper...

Article
Full-text available
This paper presents a novel approach to continuously monitor very slow-moving translational landslides in mountainous terrain using conventional and experimental differential global navigation satellite system (d-GNSS) technologies. A key research question addressed is whether displacement trends captured by a radio-frequency “mobile” d-GNSS networ...
Article
This is the second volume focused on geoethics published by the Geological Society of London. This is a significant step forward in which authors address the maturation of geoethics. The field of geoethics is now ready to be introduced outside the geoscience community as a logical platform for global ethics that addresses anthropogenic changes. Geo...
Article
Landslides along a 10 km reach of Thompson River south of Ashcroft, British Columbia, have repeatedly damaged vital railway infrastructure, while also placing public safety, the environment, natural resources, and cultural heritage features at risk. Government agencies, universities, and the railway industry are focusing research efforts on a repre...
Article
To fully understand tsunami hazards along Canada’s Pacific coast we must consider all potential sources including local and region-wide earthquakes, volcanic activity, slope failure events and bolide impacts. Furthermore, as climate changes, future extreme meteorological conditions will exacerbate slope failures on steep and over-steepened slopes,...

In this paper, we examine the influence of the 27 October 2012, Mw 7.8 earthquake on landslide occurrence in the southern half of Haida Gwaii (formerly Queen Charlotte Islands), British Columbia, Canada. Our 1350 km² study area is undisturbed, primarily forested terrain that has not experienced road building or timber harvesting. Our inventory of l...

Landslides in the Western Canadian Sedimentary Basin are widespread, primarily along valley slopes, yet rarely make the news and their impact to the Canadian economy is underappreciated. In preparing this paper, Canadian landslide practitioners from industry and government came together to estimate order-of-magnitude financial costs of prairie land...

A 6.3 m tsunami swept through Kitimat Arm, British Columbia in 1974. An even larger wave struck and damaged the Northlands Navigation dock at Kitimat and the Haisla First Nation docks at Kitamaat Village the following year. Further down the fjord, two large coastal block failures were observed on the fjord walls across from the Gitga'at village of...

Loss of matric suction in the head scarp has the potential to trigger increased movement in metastable landslides. Measurements taken from in-place dielectric permittivity sensors installed in the head scarp and within the slide mass are analyzed based on temporal trends combined with weather station and displacement monitoring data. Fluctuations i...

The Thompson River valley, south of Ashcroft in British Columbia, Canada, has experienced several landslides since the mid-1800s. The national railways that run along the valley cross a number of these landslides. All the landslides occur in glacial deposits, typically sliding on weak clay layers. Some have failed rapidly to very rapidly and are cu...
