Dramatic footage of sheeting joint collapses in Espirito Santo in Brazil, via Facebook<\/p><\/div>\n
.<\/p>\n
The collapse occurred in Pancas County of Espirito Santo in an area of granite massifs. The video was posted by Heinrich Theodor Frank, who provides the following comment (this is a tidied up Google Translation):<\/p>\n
\nYesterday,<\/span> in the city of Pancas (ES), something happened very scary – and was filmed<\/span>!<\/span>\u00a0 Granites and<\/span> other rocks<\/span>, when they change of course they do so from the outside. Successive rock levels<\/span> are changed and<\/span> the rock begins to form “shells” like an onion [this is exfoliation jointing].<\/p>\nThe same process<\/span> happens with whole mountains, where there is a stress relief process<\/span>. There are good internet pictures of granites in arid regions, where the “shells” are well<\/span> exposed<\/span> because they are not hidden beneath vegetation (search for “spheroidal exfoliation”).<\/span> In<\/span> Pancas the “shells” of granite changed collapsed down the hill – with everything<\/span> that was in<\/span> them. The news is available on the network, but the footage of this is an extraordinary record<\/span> of this event. After an initial collapse, the staff began to film the dust cloud and therefore<\/span>, succeeded in filming the next “shells” sliding downhill. An unpublished video in the world!<\/span><\/span><\/div>\n<\/blockquote>\n<\/div>\n
The video starts after the first collapse (which has clearly generated a vast amount of dust).\u00a0 After a hiatus there is then a series of successive collapses as the joints unload.\u00a0 This is the second major collapse event:<\/p>\n

A cliff collapse from SW China<\/h5>\n
I don’t think I have come across this one before<\/a> (but it is now hard to keep track!).\u00a0 It is a dramatic cliff collapse from China, but the commentary provides no additional information.<\/p>\n
