Predicting Landslides

This post continues on The Trouble With Landslides by investigating in more detail why predicting how landslides will behave is challenging. Small landslides are fairly easy to predict: rockfalls essentially follow trajectories that can be predicted with relatively straightforward physics, … Continue reading

The Trouble with Landslides

Landslides are among the least sexy disasters. Mud and rocks are less photogenic than lava, a single event usually impacts fewer people than an earthquake, hurricane, or tsunami, and anyone who lives in big, flat places will probably never encounter … Continue reading

Transportation Cooridors in British Columbia

Low population density in British Columbia, with populations clustering along the southern border, and strong geomorphic north-south obstructions conspire to limit transportation and communication corridors. The corridors are often multi-purpose with rail, roads, telecommunications, and pipelines in close proximity, and … Continue reading
