Tbilisi: a 500,000 cubic metre landslide, probabkly triggered by road construction<\/h4>\n

In Tblisi in Georgia, a 500,000 cubic metre landslide has developed on the edge of the metropolitan area, probably triggered by construction of a road.\u00a0 The landslide which is described in articles in both Vestnikkavkaza.net<\/a> and JAM News<\/a>, is impressive in scale:-<\/p>\n

The image above shows a very large fissure that defines the mobile block.\u00a0 This appears to be sliding towards the left of the image, where the slope has been cut fro road construction.\u00a0 The image below provides a sense of the motion:<\/p>\n

The under-excavation road is being protected from minor rockfalls by a barrier of what appears to be concrete blocks.\u00a0 This suggests that the movement has been developing for a few days at least.<\/p>\n

The landslide has developed on the margins of a new road linking two residential areas of Tbilisi \u2013 Vashlijvri and Nutsubidze.\u00a0 I believe that the Google Earth image below shows the site.\u00a0 This image was taken in July 2020:-<\/p>\n

The JAM.net article provides some insights from local experts<\/a>:<\/p>\n

\u201cThe earth may descend tomorrow, the day after tomorrow, or in a year, but it will definitely come down. Where and how \u2013 the issue of modeling, it needs to be assessed,\u201d said Geologist Tea Godoladze, director of the National Center for Seismological Monitoring.<\/em><\/p>\n

According to her, geologists and surveyors who have already made the initial assessment have come to the conclusion that cracks in the slope are the result of improper intervention in the environment. And, most likely, a landslide cannot be avoided.<\/em><\/p>\n

The danger exists both in the immediate vicinity of the landslide and in other areas, since the support system is also broken there, said geomorphologist Lasha Sukhishvili.<\/em><\/p>\n

\u201cThe speed of the landslide is still unclear. This can take years. But, for example, due to heavy rain or some vibrations, the process may speed up a little,\u201d said Sukhishvili.<\/em><\/p>\n

Managing a landslide of this scale will be challenging.\u00a0 I am reminded of the Rattlesnake Ridge landslide<\/a>, where the pragmatic solution has been simply to allow it to move whilst monitoring it carefully<\/a>.<\/p>\n
