Swallowing up half of the front lawn, it was 35ft wide and 20ft deep. Last week, a hole as deep as a double-decker bus is high suddenly opened up in the back-garden of a house in South-East London, almost swallowing a child’s trampoline as the ground collapsed without warning. Had the poor owner’s daughter been rushing out to play on the trampoline, she could have very easily have been seriously injured or even killed. Two weeks ago, there was a similarly narrow escape for a family living in High Wycombe, when, overnight, a deep hole appeared  without warning in the driveway just next to the house. This time the adult daughter’s car did end up buried at the bottom of the hole, thankfully, while there was no one in it.   And in Kent last week, motorists hoping to use the M2 were left fuming by the motorway’s temporary closure, after a substantial hole — 15ft deep — suddenly appeared in the central reservation. Again, no one was hurt but had the hole opened up just a few yards away, it is obvious what a different story it could so easily have been. More
