The correct answer is - mudslides.
The hurricanes bring in a very large amount of water with them in a very short period of time. Because of this, the soil gets over-saturated with water, and this causes the surface layer of the soil to start moving. The mudslides usually appear at steep places, and they are combination of large amounts of water and soil that have mixed and created fast moving mud river. The mudslides, because of there speed and sudden appearance, are extremely dangerous, and they cause very big damage, both in human lives and material damage.
