All the while, there was a continuous loud roar and rumble. As I reached the top and turned, I saw a man about 10 feet down the hill who was carrying 2 small children. The debris flow caught him and he threw the 2 children toward the hilltop to safety, but the debris flow swept him away. The same wave also swept away 2 women near to him, and I never saw any of them again. It was the most horrible thing I have ever experienced and I will never forget it.
Most books stress large rockfalls and mudslides, and say that they stagger the imagination.
