CAUSES AND EFFECTS OF EARTHQUAKES, TSUNAMI AND CYCLONES
What are Earthquakes?
← An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust 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 with a seismometer; a device which also records is known as a seismograph. The moment magnitude (or the related and mostly obsolete Richter magnitude) of an earthquake is conventionally reported, with magnitude 3 or lower earthquakes being mostly imperceptible and magnitude 7 causing serious damage over large areas.

Effects of Cyclones
The main effects of tropical cyclones include:
← Heavy rain
← strong wind
← Large storm surges at landfall
Cyclones in India:
← Cyclones in India generally strike the East Coast; some of the Arabian Sea Cyclones strike the west coast of India as well mainly the Gujarat and North Maharashtra coast. Out of the storms that develop in the Bay of Bengal, over 58 percent approach or cross the east coast in October and November.

← The shorter side of the building should face the storm.
← buildings can be designed on a circular/ellipsoidal plan, so as to impart least wind
