This blog provides commentary on interesting geological events occurring around the world in the context of my own work. This work is, broadly, geological fluid dynamics. The events that I highlight here are those that resonate with my professional life and ideas, and my goal is to interpret them in the context of ideas I've developed in my research. The blog does not represent any particular research agenda. It is written on a personal basis and does not seek to represent the University of Illinois, where I am a professor of geology and physics. Enjoy Geology in Motion! I would be glad to be alerted to geologic events of interest to post here! I hope that this blog can provide current event materials that will make geology come alive.

More on the Oliver, British Columbia, landslide

Photograph from the Oliver Daily News, June 17, 2010.
Also on Dave's Landslide Blog on the same day.

New air photos posted on Dave's Landslide Blog show that the landslide in Oliver last Sunday was triggered by the overtopping and eventual failure of a small earthen dam high up in the catchment basin.  Rural areas all over the world are littered with these earthen dams (simply piles of soil) and many are old ill-maintained.  In this case, hikers had warned authorities two days prior to the failure that the lake behind the dam was overflowing.  The dam subsequently failed through the breach shown in the center of the upper photograph. Authorities did not warn those downstream, and there are now demands that there be compensation. An investigation is underway.

In other news today, a wall in a mining pit in Tasmania collapsed, creating a huge rockslide.

And, I've found another very interesting landslide blog in Darjeeling, India, "Save the Hills".
