June 2009 fatal landslide map
A little late, but here is the map of fatal landslides for June 2009. Regular readers will note a change in the quality of the map (for the better I hope). My achievement of the week is to teach myself GIS from scratch, so that now I can plot the data on decent quality maps. So here it is, plotted on the SRTM digital terrain model (Click on the map …

Guatemala landslide – new satellite image
The Advanced Land Imager instrument of the NASA Earth Observation satellite EO-1 has recently collected an image of the Guatemalan landslide, which they have made available online. The image is here. I have cropped it to show just the slide – it is quite useful:

Costa Rica Earthquake – the aftermath
I thought a brief follow up email to my previous posts about the Costa Rica earthquake would be useful now that we are five days post the event. So what do we now know? Well, first the final death toll is likely to be about 40, most of whom were killed by landslides. Officially, as of today, 19 bodies have been recovered and 21 more are buried under landslide debris. …

Landslide hazard and the Guatemala rockslide
As commenters on my earlier threads have pointed out (thanks to them), the location of the landslide in Guatemala can now be pinpointed using a map produced by CONRED. This map comes from a very useful report, with some good images of the rescue and recovery operation, available here. I have reproduced the map below (click on the map for a better view): Helpfully, this allows the location to be …

The Guatemala landslide – video of the failure in December
The Guatemalan landslide becomes more interesting by the day. It is now apparent that the first failure, which occurred on 14th December and killed five people (the remains of three of whom were not recovered) was also caught on video. This is available on Youtube. I have embedded it below, so should work: If not, then it can be viewed here.
Guatemala landslide
As the Guatemala landslide now fades from media prominence, Reuters have released probably the best image to date of the landslide site: It is now clear that this was a a large rockslide (not a mudslide as reported elsewhere). AP have released a good image of the site: Whilst this Reuters image shows the runout of the landslide quite well: Finally, CONRED released this image of the site to show …

Another video of the Guatemala landslide
It now appears that there are two videos of the Guatemala landslide. The second one, which is not as clear as the original, has appeared on the Telediaro 3 web site. It can be viewed here: http://www.telediario.com.gt/index.php?id=15366&tim;=# Meanwhile, there remains considerable uncertainty as to the number of victims (we may never know for certain I suspect), whilst speculation is intensifying regarding the cause. Given the clear size of the landslide …
