"British sinkhole spike prompts warning"

Woo hoo, everybody's into sink holes now, they've even finally got round to blaming them on Climate Change:

Britain is likely to face the strange and disturbing threat of more sinkholes opening up in the weeks and months ahead.

The warning comes from the British Geological Survey (BGS), which has been studying a recent spate of collapses across the country. In a typical year, geologists would expect to see one or two sinkholes appearing, but this month's tally has reached six so far...

Some rocks host networks of natural caverns while others are riddled with old mineshafts. Depending on the soil and rock suspended above of these cavities, a sudden incursion of water from heavy rainstorms can lead to massive strains and, ultimately, to collapse.
