This document summarizes different types of natural disasters connected to water: storms, floods, tsunamis, and heavy rainfall. Storms are strong gusty winds over bodies of water. Floods occur when water overflows river or lake banks or from heavy rainfall, including areal, riverine, and coastal flooding. Tsunamis are series of waves caused by displacement of water, often due to earthquakes. Heavy rainfall consists of water droplets that have condensed from vapor and fall due to gravity, impacting at increasing speeds with larger droplet sizes. All of these natural disasters can cause loss of life or property damage.
