Beichuan landslides from Google Earth
The FORMOSAT-2 image of the Beichuan area is now available on Google Earth (see here). The image is interesting as it shows that the landslides were incredibly spatially variable – for example, in the Beichuan area (which is junction of the rivers on the middle right of the image – the Google label is a little way from the main part of the town) the occurrence of landslides is very …

Sichuan – further images of giant landslides
Two further images have been sent to me of giant landslides from the Sichuan earthquake. At the moment I cannot find out where they are from, although they clearly both show the same giant landslide. Note that the valley is completely filled (which means that a lake if forming somewhere upslope) and the amazing flow structures in the landslide mass. I wonder if this is the same landslide as is …
Updated: Sichuan Earthquake aftermath – landslides are taking a terrible toll
In previous posts I have warned that landslides will wreak a terrible toll in the aftermath of the earthquake. Sadly, this appears to be all too true. Xinhua is today carrying this report: More than 200 relief workers, engaged in repairing the broken roads in the quake-stricken Sichuan Province, had been buried in mud flows over the past three days, said Dai Dongchang, an official with the Ministry of Transport …
Beichuan – what happens when a massive rockslide hits a town
I am not normally a fan of Chicken Noodle News (CNN), but they have an interesting report detailing the damage in Beichuan resulting from the impact of the rockslide. It is worth a view. I cannot find a way to link to the original report, but there is a good quality version of it here. AP image captioned: Rescue workers search collapsed buildings in Beichuan, China’s southwest Sichuan province, Sunday …

In particular, images are now available of Doghekou, which is one of the landslides that has blocked the river upstream of Beichuan. These three landslides have together entombed an estimated 300 families, which would indicate …

Satellite imagery of the landslides in the Sichuan earthquake
Now that there is a brief weather window, satellite imagery is starting to emerge of the Sichuan Earthquake zone. At present most of these images are too low resolution to allow detection of the real damage to the buildings (which is notoriously difficult to achieve), but they are excellent for looking at landslides. The best to date that I have seen has come from the Taiwanese Formosat-2 instrument, which is …

Updated 16th May (twice): Sichuan Earthquake landslide images
I thought a thread showing some news images of landslides triggered by the Sichuan earthquake would be useful. The first image shows vividly the likely impact of landslides in this area. AP photo entitled “Buildings are destroyed by landslides following Monday’s powerful magnitude 7.9 earthquake in Beichuan in Mianyang city in southwest China’s Sichuan Province Tuesday, May 13, 2008. A signboard atop the building at left reads: Beichuan Hotel” Xinhua …
