by the Resilience and Emergencies Division of the <a rel=\"noreferrer noopener\" href=\"https:\/\/www.gov.uk\/government\/organisations\/ministry-of-housing-communities-and-local-government\" target=\"_blank\">Ministry of Housing, Communities and Local Government<\/a> to provide assistance to Mansfield District Council, who are managing the site. We visited the landslide on 18 and 19 November 2019 to carry out a walkover survey and LiDAR scan of the landslide and surrounding area. The landslide has been entered into the BGS <a href=\"https:\/\/www.bgs.ac.uk\/geology-projects\/landslides\/national-landslide-database\/\">National Landslide Database<\/a>, ID 20744\/1.<\/p>\n\n\n\n<p>Mansfield District Council employed specialist consultants, Fairhurst, to manage the removal of the landslide debris (reported to us as approximately 1300 tonnes) and design a scheme to stabilise the slope. <\/p>\n\n\n\n<p>From this brief survey, it is clear that this is a complex situation and requires intrusive and detailed geological, geotechnical and hydrogeological analyses to understand the slope stability, taking into account the potentially highly varied depth of weathering in the sandstone, the hydrogeology of the area and the nature of the upper slope where the landslide initiated, including the overburden.<\/p>\n\n\n\n<p><strong>This BGS survey was carried out after the landslide debris had been removed and access to the upper slope was not possible. It is an independent and impartial assessment and is not related to the work that Fairhurst have undertaken on behalf of the Council.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">LiDAR survey<\/h2>\n\n\n\n<p>We carried out a <a href=\"https:\/\/www.bgs.ac.uk\/geology-projects\/geomatic-surveys\/#lidar\">terrestrial LiDAR survey<\/a> using the Riegl VZ-1000. This survey comprised ten scans from eight locations totalling over 735\u00a0million data points. Six of these scans were captured within the quarry and two incorporate a section of the road above the quarry slopes on Berry Hill Lane. From this, we made 3D measurements and observations about the geology. Any future surveys can be compared with this baseline survey to determine change.<\/p>\n\n\n<figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/02\/LiDARextent.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Figure 4: extent of LiDAR survey in Berry Hill quarry showing the landslide of November 2019.

In Nottinghamshire, it is often characterised as weak rock, containing extremely weak members; its strength decreases by 30\u201340 per cent when saturated (Sattler, 2018).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Weathering of the Chester Formation<\/h3>\n\n\n\n<p>Understanding the weathered state of the Chester Formation is an important factor when considering slope stability at the Berry Hill quarry site. This is because the rock is fundamentally weaker and more prone to breaking apart when weathered. According to Spink and Norbury (1990) the weathering of the Sherwood Sandstone Group is defined by the gradual disintegration from competent sandstone into loose sand.<\/p>\n\n\n<figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/02\/SherwoodSandstoneOutcrop_Mansfield.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Map of thickness from the surface to competent rock in the Sherwood Sandstone Group outcrop in Nottinghamshire.

In the case of the Berry Hill quarry landslide, the site (NGR 454764 359605) falls within the area of greatest weathering depth, as determined from a survey of over 500 borehole logs. These were used to produce the interpolated map of weathering thickness to competent rock. <\/p>\n\n\n\n<p>Whilst the upper depth of highly weathered soil (1\u20132\u00a0m depth) is determined primarily by freeze\u2013thaw processes associated with the last glaciation, this deeper weathering leading to very weak rock is possibly linked to deep fracturing. This would potentially provide drainage pathways and cause greater removal of carbonate matrix cements in the rock. <\/p>\n\n\n\n<p>Importantly, there is a high degree of spatial variability in the depth of weathering within the sandstone that is not necessarily visible at the rock face but can lead to changes in its chemical and physical characteristics.<\/p>\n\n\n<figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/02\/faultingPattern_Mansfield.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Maps showing (a) known faulting in the Carboniferous strata underlying the Sherwood Sandstone Group outcrop and that faulting identified from the &#8216;coal abandonment plans&#8217; where the throw is greater than 70 m and (b) the identified faulting pattern in the Carboniferous strata.
