David Petley from Dave’s landslide Blog has been on a trip to Sichuan Province in China, site of last May’s tragic earthquake and deadly landslides. He has posted a 5-part series at his blog with some incredible pictures and first hand accounts of the effects of the disaster on the landscape and the people and on the reconstruction efforts.

The Utah Geologic Survey has released a "Landslide Susceptibility Map of Utah". They apparently relied quite heavily on GIS based thresholding of existing slope angles but only after they had statistically analyzed failure angles for particular geologic units. So it sounds like they throw the known landslides, the geologic map of Utah and a DEM into the GIS a blend it all up. Perhaps a slight oversimplification!
Indonesia is planning to build what will be the World’s longest suspension bridge to link up its two main islands of Java and Sumatra. The total length will over 30-km with a (max?) height of 70-m so ships can pass underneath. The catch is that the bridge will be located on the Pacific Ring of Fire, the boundary between the Asian and Australian tectonic plates and one of the most seismically and volcanically active areas in the world. There have been several recent earthquakes greater than magnitude 7, not to mention the earthquake that caused the 2004 tsunami. The bridge will be built to withstand a magnitude 9 earthquake. Oh, and in case the seismic concerns weren’t great enough, the bridge will pass within 50-km of the volcano Krakatoa. The estimated cost of the bridge is $12 billion ($AU?).
