The research legacy of the Wenchuan Earthquake: a new review

The research legacy of the Wenchuan Earthquake: a new review Ten years ago the most destructive seismic event in a generation, the Wenchuan Earthquake, struck the Longmenshan in Siichuan Province in China.  I covered the event on this blog – indeed on 12th May 2008, at 07:27 UT, 29 minutes after the Earthquake occurred, I wrote: “it is reasonable to assume that this earthquake will have triggered large numbers of …

Landslides, forests and pandas – conservation and the Wenchuan earthquake

The vast number of  landslides triggered by the May 2008 Wenchuan earthquake, and in its aftermath has been extensively described, not least on this blog.  One of the documented impacts of these landslides was the well-documented loss of habitat of the giant panda (A. melanoleuca) due to extensive forest loss.  However, there is a great deal more to that story than meets the eye, as a newly-published paper by Vina …

Continued debris flow activity in the Wenchuan (Sichuan) earthquake area

A frequently-forgotten but potentially very damaging impact of large earthquakes in mountain areas is the increased occurrence of debris flows and other landslides in the following years.  Whilst these events continue to represent a hazard in their own right, they frequently also cause changes to river dynamics, with resultant high levels of damage.  This problem was illustrated all too clearly in a small village that we visited close to Beichuan …

Beichuan town – the old and the new

On Wednesday I was fortunate to be able to return to Beichuan (see my images of the town, taken last year), the heart of the earthquake-affected areas in Sichuan.  Well, to be more accurate I visited the viewpoint looking down on the town.  It is clear that debris flows continue to be a major problem at this site: For those who don’t know the site I have annotated the image …
