4. Reports say there's very little movement that's being found in the tip? The danger has changed to the whole of the school? [G/LW]
Monitoring shows downward movement of the Quarry Spoil Tip (towards the school). Our previous assessment suggested that the Quarry Spoil Tip was Marginally Stable, i.e., that it was likely to fail at some time in response to destabilising forced reaching a certain level of activity. The information from the inclinometers suggest that the Quarry Spoil Tip is moving and is Actively Unstable, i.e., destabilising forces are producing continuous or intermittent movements.
Refer to report: 26th February 2020 - Godre’r Graig Village Preliminary Hazard and Risk Assessment – 7372e.3337.
Based on conditions at the time of the assessment, the consequences to the school of a landslide were significantly different than for residential houses. The direction of travel of a landslide from the quarry spoil tip would likely be perpendicular to the slope contours, i.e., towards the school – please refer to figures 12-14.
