3. Why did it happen?
The moor had been saturated and the water had no-where to go. It ran down the Valency valley, and into the village.

6. An eyewitness account
Alan Graham was in Boscastle with his family on holiday. He was in the tourist office with them when the flooding started.
"The front door of the visitors centre smashed through and torrents of water came in until, in the end, half the visitors' centre got smashed away," he said.

7. An eyewitness account (cont.)
"We got ourselves on to the roof. We were there for about half an hour in freezing cold rain until the helicopter came along and picked us up, one by one.
"There were 60ft trees just going down the river like matchsticks - as soon as one of those hit the front of the visitors centre, it just wiped away all the structure of it."
