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.

Decision to Blast at Attabad

Dave Petley reports that there has been a decision to blast out some of the rocks in the channel at Attabad, but there is no information about which boulders are to be blasted. The large "boulder" at the top of the spillway is shown at the right. There has been considerable erosion around it in the past few days.  For those who raft in the Grand Canyon, the image conjures up nightmares of the bad waves of Lava Falls in the Grand Canyon!

There is, however, a second big boulder downstream and it's not clear to me that blasting the first one will do anything but move the choke point downstream to this boulder.
