The picturesque Sea Cliff Bridge South of Sydney, Australia has been built only 7 years and is already threatened by a landslide. Portions of the site have moved 1.5 m since 2006. The Australian Roads and Maritime Services (RMS) department reportedly has three options to consider for stabilizing the bridge, and all three involve the construction of a seawall. The project, which was completed in 2005, was designed to avoid rockfall but was not meant to deal with landslide issues. [Source: Illawarra Mercury. Image: SMH]

Geologic Hazard Photos
The National Geodetic Data Center (NGDC) of NOAA has an online collection of photos of various geologic hazards. Many of the photos are from older sets of 35mm slides that have been digitized. They are free to use provided you credit the photographer and the NGDC as the source. The would be really useful for educators and for powerpoint presentations. The only drawback is that they are in TIF format and some of them could use some retouching. (Photo by University of Colorado, made available by NOAA/NGDC)
