• The vibrations called seismic waves are generated from earthquakes that travel through the Earth and are recorded on instruments called seismographs.
• Types of Earthquakes: Fault Zones, Tectonic Earthquakes, Volcanic Earthquake, Human Induced Earthquakes.
• Earthquake in India:
  • India is one of the highly earthquake affected countries because of the presence of technically active young fold mountains - Himalaya.
  • India has been divided into four seismic zones (II, III, IV, and V) based on scientific inputs relating to seismicity, earthquakes that occurred in the past and tectonic setup of the region.
