* Hypocentre
- The inner point in the earth surface from where the earthquake originates.
* Epicentre
- The point on the surface of earth just above the hypocentre.
* Seismic wave
The waves of shaking or vibration that travel in different direction from the epicentre.
* Seismographic
- Any instrument used to measure intensity or magnitude, speed and direction of earthquake.
* Richter Scale
- A Scale ranges from 0 to 9 to measure the intensity of earthquake.
- named after American seismologist Charles F. Richter.
- Earthquake with 7 + Richter scale is destructive.
* Volcano

- Turning off electric and gas appliances during earthquake.
- best to assemble in an open place.
- be in touch with radio and tv to know about preventive measures of earthquake.
* Effects of Earthquake
- disappearance of high altitude and formation of newland
- loss of life and property
- destruction of infrastructure of development.
- break out of epidemics and other problems.
- causes natural calamaties like landslide, soil erosion, Tsunami etc
- cracking of earth surface and cause volcano.
