A River of Mud and Volcanic Ash at 100km/h...

The recent rains in and around Yogyakarta have given rise to a new Mount Merapi related threat; rivers of mud and volcanic ash.

What is most scary about this photo (courtesy of Antara) is that this river of mud and volcanic ash is flowing at about 100 kilometres per hour. The mud and volcanic ash has been transported from Mount Merapi along the Code River which flows from the side of the mountain right through the centre of Yogya.

Nature at its very best, or is that at its very worst?
