I came across this interesting product for structural/geotechnical monitoring of cracks in 3 dimensions. Most crack monitors are designed for monitoring in 2 dimensions, this one can measure movement out of the plane of monitoring. I like that the markings are laser-etched so the simple device should last for a long time. Price is $40/each from Quality Plus Engineering, LLC.

Landslide Videos from Brazil
Dr. Dave has posted links to a few scary landslide videos from the recent heavy rains affecting the Santa Catarina province of Brazil. This latest one shows an ambulance being swept off a road by a “small” landslide. The ease with which the vehicle is moved is quite impressive. It didn’t appear that anyone was injured in this particular landslide but I’m sure there might have been some underwear changing involved. Elsewhere in the region people have not been so lucky and there is a heavy death toll. Click through for two videos.
