Disaster may occur in different forms and can remain from hour to days and weeks. Following are different types of disasters

Types of Natural Hazards

It is an adverse condition occurred naturally.

Astronomical Hazards

  2. Comet crashes
  3. Geo-magnetic storms
  4. Meteor sowers

Atmospheric Hazards

  1. Blizzards extreme cold, fog, freezing rain or drizzle
  2. Heat waves
  3. Hurricanes
  4. Snow storm, ice dogs and ice storm, frost, hail storms

  4. Landslides
  5. Land subsidence and sinkholes
  6. Sand and dust storms
  7. Submarine slides

Hydrological
