A Natural Phenomenon
Beside thunderstorm, we have learnt about the cyclones. To some extent our weatherman predicts the coming of rain and a cyclone. But, earthquake is one natural phenomenon which cannot be predicted.
An earthquake is the sudden shaking of the earth caused by deep layers of the rocks inside. The rocks under the earth slide over one another from time to time, bringing about disturbance of the surface 0f the earth. This disturbance is the earthquake. It is measured on a scale called Richter Scale'. The Richter Scale measures the
magnitude of disturbance on a scale from 1 to 10. The damage begins when the earthquake is 5 or above and disastrous beyond 6.5 or Richter Scale.
The earthquake may cause damage to the buildings, animal and plant population on the earth. Earthquake at a place surrounded with sea may cause TIDAL WAVES in the sea around. The waves move as a high wall of water to distant islands and may brings disaster for the people living along the coastline. Japanese name for tidal waves (or seismic waves) is Tsunami. Last Tsunami occured on 26th Dec, 2004 after an earthquake in Indonesia. Causing more than 10,000 deaths in India along the East coast. Tsunami in India was the result of 20 m high, towering all of seawave, striking the shores, drowning people and the dwellings and taking away all on the way alongwith them while receding.
Today, there is a fashion to construct malls and mutistorey residential and commercial complexes. These are prone to big damage from earthquakes. For the construction of any building precautions be taken to make it
"quake safe", and for this a qualified architect must be consulted. The foundation of the building should be deep, broad and rolling. Roofs should be of light material and the fixtures should be light.
