I want to know the answer to the following question:
What causes flooding, property damage, and loss of life?
All the background I'm provided with is that "In the 17th century about 2500 people were killed by an avalanche in a village on the French-Italian border; in the 19th century 120 homes in a village near Zermatt were destroyed by an avalanche.". Is that enough to answer the question?
Answer: no
