A Natural Disaster, Earthquake

Standard

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.

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)

– 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

I have come to this frightening conclusion that i'm the decisive element. It is my personal approach that creates the climate. It is my daily mood that makes the weather. I possess tremendous power to make life miserable or joyous. I can be a tool of torture or an instrument of inspiration; I can humiliate or humor, hurt or heal in all situations, It is my response that decides whether a crisis is escalated or de-escalated, & a person is humanized or de-humanized. If we treat people as they are, we make them worse. If we treat people as they ought to be, we help them become what they are capable of becoming..
