Puzzle 2: slightly more tricky. The upper photo was taken at 10am on Boxing Day, 26 December 2012. The lower photo was taken 48 hours later at 10am on 28 December 2012, although we believe this fall actually occured late on Boxing Day afternoon.
Answers: In both cases there has been a significant land slip which would have severely injured or killed anyone caught in its way. The cliff is still moving. Just because this site and the BBC showed some impressive video footage last weekend, it doesnt mean the cliff fall is over and the area is now safe. Quite the opposite.
More photos a bit later.
