      [Many thanks, I had not. I will put a post up about it this weekend. D.]

  • Kumamoto earthquake: post-seismic landslides
    One of the most serious concerns about the Kumamoto earthquake in Japan was that the timing, shortly before the rainy season, meant that there was high potential for […]

    • This spike in slides makes perfect sense to me.
      In 1992, we had the 7.1 Petrolia quake sequence here on the north coast of CA.
      In 1995, I came to the coast as a geologist working as a regulator in the timber industry. This was a boom time and I was very busy evaluating numerous timber projects in the mountainous countryside.
      The winter of 1996-1997 was one of the hardest on record, and everything that could blow out, did so, most particularly within 30 to 40 miles of the epicenters. Since that, rainfall was lower (actually went into a drought cycle) and things were relatively quiet, slide-wise.
      This past El Nino winter, we had heavy rains again. Starting to see occasional big slides, but nothing like the years right after the Petrolia sequence.

    • Looks like you might be missing one. The 2012 landslide at the Beaminster Tunnel in Dorset that sadly killed two people. All the southern England ones you show are on the coast; this one was well inland.


      [Good point – I am not sure if this is a mislocation by the team or if they missed the landslide. The latter would be surprising as it was a very high profile event. D]

  • Landslide video: a massive landslide takes out a truck in Peru
    I know nothing about the circumstances of this video, which was reportedly shot on a mountain road in Peru, or how it worked out for the driver of […]

    • Hello Dave,

      I work at the Landslide Research Team of the Geological Survey of Peru, and I can give you some details about this event: It was in the amazonian region of El Marañon and occurred last April 2016. Tree small villages were isolated because of the landslide and it took 3 days to re-open the road. Sadly, 7 person were found dead in the truck.

      All the best!


    • I think this is the landslide shown here from last year. One of the videos must be flipped horizontally, but the truck and pickup both look the same, and the three people in the screen cap above look like the same three at the beginning of the below video. And you’re right, it didn’t end well for the driver. The two videos must have been taken from almost the same place.


    • So sad to watch. They backed away at one point, probably would’ve survived if they’d stayed put out of the way.

    The Croatian news website Dulist has a story this week about a boulder that came to tea in a house in Dubrovnik.  The pictures are quite startling:-

    • The photos early on make me suspect that a significant amount of the upper part of the blockage is composed of large slabs. Indeed the ripple patterns in the channel before the water steeply descends is indicative of flow over a large slab.

      I wonder if this paper addresses the possibility of slabs and their effect on any partial releases. Not willing to buy access to the paper.

  • Granbury, Texas
    Over the weekend an interesting, but to those involved distressing, landslide developed at the town on Granbury in Texas, threatening a four-storey apartment block.  NBCDFW have a couple of […]

    • A comparison of the Fox and Google Earth photos shows that something happened below the current water line. In the GE photo, the wall above the “toe weight” (if that is what it is) is a straight line. In the Fox photo, the center portion of the sea wall is at or below the water line, while the dock or landing on the left is still above it (and appears to be askew). It would be interesting to know what the topography is below the water line. The multiple retaining walls suggest that the ground under the structure was built up and is not the natural slope. If those were cracks in the GE photo, someone should have seen this coming.

    • Note the 1 pre- and 3 post-2014 repairs to the concrete road to the left of the apartment building.

  • The GFDRR ThinkHazard! tool
    Yesterday the new GFDRR ThinkHazard tool was launched.  This is a new web based system for developing countries that allows a basic assessment of hazard across a range of perils on a […]

    • After just five minutes of browsing around the Think Hazard Tool, as a geologic hazard professional I am having an extreme anxiety reaction. While there is language indicating that the tool is for areas where more detailed information is severely lacking like in developing countries, one can search anywhere on the planet. In areas in countries or municipalities that have much higher quality data, there are no links or even language describing where to go to find better site specific data. For example the Colorado Front Range has a detailed history of destructive and deadly flash floods, yet three of the counties most affected by damaging floods mapped and listed as very low or low river flood hazard. In fact, two of the three counties listed as very low hazard contain the bolded language “flood hazard does not need to be explicitly considered for your project” in the description. From a site specific perspective, this is completely false! Further there is no indication where one should look for all the incredible flood hazard resources that are available for development planning in this area that would indicate how completely wrong the bolded statement is. I can understand the drive and even utility for something like this, but it should be completely directed at areas where there is truly no more detailed information or links to better information must be included. Developed areas with maturing natural hazard planning resources should be completely omitted or grayed out with a note that more detailed information is available from local or national governmental authorities and that information should be consulted. The misuse potential of this tool is massive!
