The Xinjiang earthquake (also known as the Kunlun Earthquake) on 12th February is now known to have triggered at least some landslides. A fascinating image has been posted on Xinhua of some of the hillslopes affected by the earthquake:
These appears to be shallow rockslides in weathered material – interestingly, most of the slips are on the gully flanks, but do not seem to have progressed to full failure. The more I look at this image the more landslides I see! I find some of the images from yesterday interesting too – for example, this image shows clear signs of old landslides – I have annotated the multiple tension cracks on one of these landslides:
The only obvious feature that could be an earthquake induced landslide is highlighted with an arrow (although I am not sure that even this is actually a landslide). There is another possible small slide in the complex further along the valley. If this earthquake was not large enough to reactivate these landslides, I wonder what the original trigger was.
