Earthquakes are a common occurrence, rumbling below Earth’s surface thousands of times every day. But major earthquakes are less common. Here are some things to do to prepare for an earthquake and what to do once the ground starts shaking.
Safety Tips
* Have an earthquake readiness plan.
* Consult a professional to learn how to make your home sturdier, such as bolting bookcases to wall studs, installing strong latches on cupboards, and strapping the water heater to wall studs.
* Locate a place in each room of the house that you can go to in case of an earthquake. It should be a spot where nothing is likely to fall on you.
* Keep a supply of canned food, an up-to-date first aid kit, 3 gallons (11.4 liters) of water per person, dust masks and goggles, and a working battery-operated radio and flashlights.

* Know how to turn off your gas and water mains.
If Shaking Begins
* Drop down; take cover under a desk or table and hold on.
* Stay indoors until the shaking stops and you’re sure it’s safe to exit.
* Stay away from bookcases or furniture that can fall on you.
* Stay away from windows. In a high-rise building, expect the fire alarms and sprinklers to go off during a quake.
* If you are in bed, hold on and stay there, protecting your head with a pillow.
* If you are outdoors, find a clear spot away from buildings, trees, and power lines. Drop to the ground.
* If you are in a car, slow down and drive to a clear place. Stay in the car until the shaking stops.

In Indian subcontinent Earthquake Zone are categorically distributed as follows:
- Earthquake Zones in Indian Sub Continent
Zone 5: Covers the areas with the highest risks zone that suffers earthquakes of intensity MSK IX or greater. The IS code assigns zone factor of 0.36 for Zone 5. Structural designers use this factor for earthquake resistant design of structures in Zone 5. The zone factor of 0.36 is indicative of effective (zero period) peak horizontal ground accelerations of 0.36 g (36 % of gravity) that may be generated during MCE level earthquake in this zone. It is referred to as the Very High Damage Risk Zone. The state of Kashmir, Punjab,the western and central Himalayas, the North-East Indian region and the Rann of Kutch fall in this zone.
Generally, the areas having trap or basaltic rock are prone to earthquakes.
Generally, the areas having trap or basaltic rock are prone to earthquakes.
Zone 4: This zone is called the High Damage Risk Zone and covers areas liable to MSK VIII. The IS code assigns zone factor of 0.24 for Zone 4. The Indo-Gangetic basin and the capital of the country(Delhi, Jammu)and bihar fall in Zone 4.
Zone 3: The Andaman and Nicobar Islands, parts of Kashmir, Western Himalayas fall under this zone. This zone is classified as Moderate Damage Risk Zone which is liable to MSK VII. The IS code assigns zone factor of 0.16 for Zone 3.
Zone 2: This region is liable to MSK VI or less and is classified as the Low Damage Risk Zone. The IS code assigns zone factor of 0.10 (maximum horizontal acceleration that can be experienced by a structure in this zone is 10 % of gravitational acceleration) for Zone 2.
