Part three of the series of posts on landslides from the Christchurch earthquakes, this time looking at topographic amplification of shaking, as shown by building damage.

Part two of the series of posts on landslides from the Christchurch earthquake sequence. This post shows rockfalls from the Port Hills area.

The first set of images of landslides triggered by the recent Christchurch earthquakes in New Zealand. This set show a house that has been struck by a large boulder.

Two articles have been published this week in Science Express, the rapid online version of the journal Science, on the mechanics of the rupture event of the M=9.0 Tohoku-Oki Earthquake in Japan earlier this year.  Both shed some light on the reasons why the earthquake was so immensely damaging.  In the first, Simons et al. (2011) (NB link is a pdf, as the two below) have investigated the magnitude of …

GNS Science in New Zealand have been working tirelessly since the Christchurch Earthquake to assess and mitigate the hazards associated with rockfalls induced by the shaking.  They have produced an excellent five-minute video, presented by my former PhD student Chris Massey, which provides an overview of the range of rockfall types, describes the damage that they caused, and outlines the approaches that can be used to deal with them.  The …

A brief article highlighting both the ongoing hazards from the Attabad landslide in Pakistan and a major earthquake in the Himalayas

A small number of photos of the state of the earthquake affected areas in Sichuan Province, China.

This post provides details of an analysis of the loss of life from landslides triggered by earthquakes. It is based on a presentation to be given at the International Symposium on earthquake induced landslides in Chengdu this morning. A full PDF of the presentation is available on the site.

A stunning set of GNS images and information about the rockfalls and landslides caused by the February 2011 earthquake in Christchurch, New Zealand

A remarkable video has emerged on Youtube showing liquefaction occurring in real time during the Sendai earthquake.
