A Natural Disaster, Earthquake

earthquake1An earthquake is the result of a sudden release of energy in the Earth’scrust that creates seismic waves. The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale, also referred to as the Richter scale. These two scales are numerically similar over their range of validity. Magnitude 3 or lower earthquakes are mostly almost imperceptible and magnitude 7 and over potentially cause serious damage over large areas, depending on their depth. The largest earthquakes in historic times have been of magnitude slightly over 9, although there is no limit to the possible magnitude.

Effects of Earthquake

– Shaking and ground rapture

– Landslide and avalanches

– Fires

– Soil liquefaction

– Tsunami

– Floods

– Loss of life and property

– Damages to infrastructure

Major preventive steps during Earthquake

Earthquake is a sudden disaster. Thus to reduce risk from the impacts of earthquake here are some major preventive steps as follow:

– If you are inside your home then search for the safe location ( under table or desk, bed)

– Once you feel the shock of wave then immediately turn off the source off fire

– Don’t panic, take time and go to the safe place

– Once you feel the shock of wave, let the door open and have an emergency exit

– If you’re outside then protect your head from getting injury and stay away from harmful objects

– Follow the instructions given by the employees if you are in any department store, cinema hall or business complex

– Park the car at the left side of the road if you’re driving

– There’s more probability of landslide, so stay away from such prone areas

– Carry the primary things with you while you go to the safe place

– If the means of communication are working then listen to them and follow the instruction
