will remember the Kolontar dam failure event in Hungary early last month (see image to the left).\u00a0 Based on the images published of the event, I <a href=\"https:\/\/blogs.agu.org\/landslideblog\/2010\/10\/06\/interesting-images-of-the-ajkai-timfoldgyar-tailings-dam-accident-in-hungary\/\">speculated a couple of days later<\/a> here that the failure of the dam might be associated with problems with the foundations.<\/p>\n<p>In the last week newspaper reports in Hungary have suggested that the investigation does indeed suggest that foundation failure may be the cause of the accident.\u00a0 <a href=\"http:\/\/www.blikk.hu\/blikk_aktualis\/harminc-eve-tudtak-hogy-veszelyes-a-tarozo-2032272\/\">This article<\/a> in particular addresses this issue directly.\u00a0 It is in Hungarian, and my skills in that language are somewhat rusty, so I have had to rely upon the Google translation service.\u00a0 My corrected version of the Google translation of the salient part of the article is that the dam was underlain by a slurry \/ grout wall intended to prevent seepage.\u00a0 However, deformation and fracturing of the soil occurred over a 50 metre stretch, allowing the dam wall to move forwards and fail.<\/p>\n<p>The article says that further investigations are needed, but this would seem like a logical interpretation based upon the evidence available from this distance.\u00a0 It will be interesting to see the nature of the final report in due course, and we must of course be careful not to over-interpret until the final investigation is complete.<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content
