When violent events happen outside the (1) \_\_\_\_\_\_\_\_\_\_ of humans, they are called natural disasters. Natural forces are the (2) \_\_\_\_\_\_\_\_\_\_ of these events. There are many kinds of natural disasters, and they can result in (3) \_\_\_\_\_\_\_\_\_\_ of life, injury, and damage to property.

Scientists understand the factors that lead to storms, tornadoes, and floods. However, it is much more (5) \_\_\_\_\_\_\_\_\_\_ to predict earthquakes and volcanic eruptions. Some volcanos may leak gases or pour out lava (6) \_\_\_\_\_\_\_\_\_\_ erupting, but others do not give any warnings at all. It is also difficult to predict (7) \_\_\_\_\_\_\_\_\_\_ although scientists are aware of the regions where earthquakes are most likely to (8) \_\_\_\_\_\_\_\_\_\_.
