Another day, another sinkhole.
As if Southern Rail needed any more excuses for their appalling services to be disrupted, a small sinkhole was discovered under the tracks at Forest Hill, close to the site of a larger one which affected services last month.
It's not the first this year in the UK: the image above shows a sinkhole taking out one unlucky car in Charlton in May, while there have been more reported across the country over the past couple of years.
And, of course, two days ago, there was this terrifying, swirling, watery monster that appeared in Australia:
Should we be worried? Are these crazy things that we used to see happening elsewhere in the world going to be happening more frequently over here? Will we be sucked out of our beds in the dead of night and swallowed up into a giant sinkhole of doom?
This is what you need to know.
