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.

Erosion in Action at Attabad (video available)

Photos of the situation at Attabad on June 7 (left) and June 8 (right).  The rate of erosion of the spillway has diminished during the past week as flow out of the lake now equals flow into the lake.  However, the melt season has not yet begun and discharges will have to increase over the summer.  Apparently authorities are contemplating whether or not to dynamite the region at the top where a large boulder constricts the flow.  Such a move would be very controversial and potentially dangerous, with the possibility of triggering more landslides in this area very real.  One hazard now is that a landslide into the lake will cause overtopping of the spillway and rapid erosion.

There is a new video of the river cutting through the landslide at Attabad.
