href=\"https:\/\/blogs.agu.org\/landslideblog\/2022\/01\/13\/pau-branco-3\/\">I have been writing about landslides in Brazil all week<\/a>.\u00a0 To cap it off, videos emerged yesterday of another landslide there, this time in the city of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Ouro_Preto\">Ouro Preto in Minas Gerais<\/a>.\u00a0 In fact, there are two remarkable drone videos, and some additional mobile phone videos, of this event.<\/p>\n<p><a href=\"https:\/\/www.youtube.com\/watch?v=DQ-whLDkSfI\">The video that has been most widely circulated is this one<\/a>:-<\/p>\n<iframe

2022 at Morro da Forca.\u00a0 Instability in the slope had been noted by local residents, and the site had been cordoned off.\u00a0 As a consequence there were no casualties, but two buildings dating from the 19th Century were destroyed.\u00a0 Reports indicate that the failure has followed heavy rainfall, although conditions were dry at the time of the landslide.<\/p>\n<p><a

Emdia.<\/a><\/p><\/div>\n<p>.<\/p>\n<p>The second video posted above is interesting.\u00a0 It shows a series of collapses at the toe of the slope as the main mass destabilises and moves.\u00a0 The power of even a comparatively small landslide is clearly illustrated by the rapid and complete destruction of presumably well-constructed historic buildings,<\/p>\n<p>Reports indicate that there (rightly) continues to be concern about the potential for a further failure at this site.\u00a0 The area remains cordoned off.\u00a0 T<a href=\"https:\/\/www.dinheirorural.com.br\/parte-de-morro-desliza-sobre-duas-casas-no-centro-de-ouro-preto\/\">here are concerns about the historic buildings on the other side of the street<\/a>, which include a hotel, a restaurant and the Arts and Convention Center of the Federal University of Ouro Preto (UFOP).<\/p>\n<p>Given the age of the buildings, this slope had presumably been stable for many decades after the initial building works.\u00a0 It would be interesting to know if any modifications to the slope had been conducted in recent years.<\/p>\n<p>Finally, the image above suggests to me that in the upper part of the scarp the landslide might have mobilised existing planes of weakness, but this remains to be confirmed.<\/p>\n<p>Brazil often receives heavy rainfall at this time of the year, and landslides are common.\u00a0 This year appears to have been quite bad again.<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share
