Astute readers will have seen that Reuters yesterday ran a syndicated story about the Tumbi Quarry landslide, and the implications for Exxon-Mobil, which was picked up by many mainstream media outlets (e.g. the Guardian today). This blog is quoted in the article. With rather fortunate timing, a few days ago I have received an image of what I am reasonably sure is the site prior to the landslide (compare the features outside the landslide area with the images in this post). I will blog on this properly later today, but as a taster here is the image. I think that this image probably predates the most recent quarry expansion, and may therefore be at least a year old.
At this point I’ll draw your attention to a couple of interesting points. First, there is a number of what appears to be shallow slips – see locations a and b below:
Second, in the unvegetated areas above the quarry scarp are some rather peculiar features running across the hillside (marked c below):
Note the excavator (?) at the toe of the quarry slope, which provides scale. These features on the hillslope might be footpaths, but if so they are very well-trodden.
Comments and interpretations welcome. More later!
