What Makes a Sinkhole a Sinkhole?

April 23, 2010 rockman Comments Off

The Florida Geological Survey probably deals with more sinkholes than most agencies. The most frequent geologic cause of sinkholes is dissolution of limestone and other soluble rocks and the collapse of the soil cover over […]

Landslides in China – Sichuan and Guangxi

July 30, 2009 rockman Comments Off

In Sichuan Province, China, they were still in the recovery process from the devastating 2008 earthquake when a series of landslides, rockfall, mudslides and flooding has hit the region. Dave’s Landslide Blog has excellent coverage as usual on the slide pictured here, which blocked a major road, hindering rescue efforts. (Photo Xinhua/Jiang Hongjing)

A remarkable video of the aftermath of a bridge destroyed by one of these rockfall / landslide events is shown below. The destruction is pretty profound. (Via Geology.com)

Also on Dave’s blog, a landslide in Guangxi caused a train to derail, killing 4 people and injuring 50. My heart truly goes out to the people of those portions of China, particularly in Sichuan as they have been through so much.

There and Back Again…Ed Medley

March 27, 2009 rockman Comments Off

Its been a while since I’ve posted in Rockman’s ramblings. But tonight as I try to wind down from a stressful drive back to Tucson from Phoenix on a very windy night, I feel the muse at work. Maybe the martini is helping too! Tonight was a meeting of the Arizona Section of the Association of Engineering and Environmental Geologists (AEG). The speaker was the 2009 AEG Jahns Distinguished Lecturer, Dr. Edmund Medley of Geosyntec Consultants.

He’s perhaps best known for coining the phrase “bimrocks” for block-in-matrix-rock. He’s also written and presented some stuff on terrestrial 3d photogrammetry for geological engineering. He’s an incredibly colorful, energetic, and genuine man who is a very entertaining and gifted writer and presenter. I was glad to meet him after trading a few emails previously. I’m not sure how he would feel about this comparison, but for some reason he reminded me of Bilbo Baggins. (Photo from EdMedley.com)
