Natural disasters can be classified into four categories, according to their causes: meteorological events (e.g. hurricanes), geological events (e.g. earthquakes), hydrological events (e.g. floods) and biological events (e.g. disease). Each type of disaster has its own unique effects on humans, ranging from property damage to loss of life. Meteorological events often cause flooding, wind damage and landslides; geological events may cause earthquakes and tsunamis; hydrological events such as floods and droughts have a devastating effect on agricultural production and human settlements; and biological events such as pandemics and epidemics can result in mass casualties.
