News of a landslide at the Bingham Canyon copper mine, one of the world's largest open-cast mines, comes as a blow to those of us affected by the current shortage of ammunition. Since cartridge cases and many bullets use copper in their manufacture, this is going to put a further crimp in supplies.
According to BoingBoing, the mine "supplies about 17 percent of U.S. copper consumption and 1 percent of the world’s. When a cog that big loses its teeth, the whole global economic machine goes clunk."
Be that as it may, the report reminded me of another, even more spectacular landslide at the Third Beach open-cast tin mine, near Pantai Remis in Malaysia, in 1993. It was captured on video by a local resident. The footage has been called the most spectacular ever filmed of such an incident, despite its relatively poor quality. Watch as the seaward 'wall' of the open-cast mine gradually collapses, letting in the water (which eventually filled the entire mine, forming a new half-mile-wide and -deep bay in the coastline). It's worth watching in full-screen mode, if you can stand the out-of-focus image.
Note how the dry land flows like water, even before the sea comes roaring in. I wouldn't have liked to be standing anywhere near that lot . . .
