Top 10 Worst Earthquakes of India
It was 26th January 2001, the republic day of India. Students were going to school for republic day celebration. Those who thought republic day as just another holiday were snoring. Leaders all over the country were hoisting the tricolor flag.
As an on-going tradition people were distributing sweets among children. Some were holding flags, some busy attaching a small flag on their shirts. Some were chatting with their friends for planning and enjoying the rest of the day.
Suddenly, news struck that an earthquake has taken place in Gujarat.
As time passed by, the news was that it is a massive one and tremendous loss of life and property took place. Reportedly 30,000 people died and many others got injured. This is the real story of the Gujarat earthquake.
Fifteen years down the line, the situation has improved, but scars remain.
There are more deadly earthquakes that India has seen. Here is the list of ten worst earthquakes that India has seen in its history.

Extreme widespread destruction took place on the following day of Christmas. The calamity was so huge that even islands in the middle of the Indian Ocean disappeared or were in 3-5 meters deep in water.
The newspapers on the following day were full of gory pictures. Mind-numbing loss of human lives with property worth thousands of crores destroyed.
One more thing I remember that newspapers were only reporting about the Tsunami. From the first page till the last page it was only and only about the Tsunami. No Sports, no business news for the following several days.

One of the most fatal natural disaster that Maharashtra has ever faced. Though the magnitude recorded was 6.4 but the destruction that it caused was massive.
The most affected areas were of Latur and Osmanabad. Invariably, this natural calamity brought attention towards this area and now Latur and adjoining areas as well-developed.

Earthquake zones of India
According to a recent study conducted by National Institute of Disaster Management about 59 percent of the area in India is prone to earthquakes. India is divided into 4 seismic zones.
Zone 5 - Very High-Risk Area - 11 % of land area in India is considered as high risk. List of states that fall in this zone are Arunachal Pradesh, Assam, Nagaland, Mizoram, Meghalaya, Tripura, Central Kashmir, Central Himalayas, Northern Bihar, Rann of Kutch, and Andaman and Nicobar Islands.
Zone 4 - High Risk Zone - 18 % of land area - Some parts of Jammu and Kashmir, Uttarakhand, Delhi, Gujarat, Bihar, West Bengal, Koynanagar in Maharashtra, and the whole of Sikkim lie in this zone.
Zone 3 - Moderate Risk Zone - 30 % of land area - Some parts of Haryana, Punjab, Rajasthan, Gujarat, Maharashtra, Telangana, Andhra Pradesh, Uttar Pradesh, Jharkhand, West Bengal, Odisha, Madhya Pradesh, Bihar, Karnataka, Tamil Nadu, and the whole of Dadra and Nagar Haveli, Goa, and Kerala fall in the risk zone.
Zone 2 - Low-risk Zone - 41 % of land area - See below the map to know areas covered in this zone.
Which earthquake hazard zone level you live in ?
Questions & Answers
Is Mumbai in an earthquake zone?
Mumbai falls in the zone 3 level which is a moderate damage risk zone. There have been instances where places marked under zone 3 have witnessed earthquakes of more than 6.0 in magnitude.
Historically, Mumbai has never seen an earthquake of more than 4.5 in magnitude. In simpler terms, one would only experience slight tremors, some disturbances but no major damages.
Mumbai is the most populous city in India, and massive construction has taken place to accommodate so many people. If there happens to be an earthquake in the range of 6.0 to 6.5, the consequences would be highly fatal.
A detailed study published by IIT Bombay in 1999 puts forth many astonishing facts:

What was the depth of these earthquakes?
Depths are divided into three categories:
1) 300 - 700 KM - Deep
2) 70 - 300 KM - Intermediate
3) 0 - 70 KM - Shallow
Shallow earthquakes are the most dangerous, with the next being intermediate earthquakes, and then deep ones.
1) Indian Ocean Earthquake, 2004 - 30 km (19 mi)
2) Kashmir Earthquake, 2005 - 15 km (9.3 mi)
3) Bihar Earthquake, 1934 - 15 km (9.3 mi)
4) Gujarat Earthquake, 2001 - 16 km (10 mi)

9) Uttarkashi Earthquake, 1991 - 11.6 km (7 mi)
10) Koynanagar Earthquake, 1967 - 15 km (9 mi)Helpful 17
What are the most earthquake prone places in India?
Before diving further, below are the terms that will help in understanding this in a better way.
• Zones: India is divided into four seismic zones when it comes to the severity of earthquakes. These are Zone 5 to Zone 2. The Zone 5 lists places with the highest risk, whereas Zone 2 has areas with the lowest risk.
Zone 5: Very High Damage Risk
Zone 4: High Damage Risk
Zone 3: Moderate Damage Risk
Zone 2: Low Damage Risk
• Seismicity: This is defined as the number of times an area is vulnerable to earthquakes. The higher the seismicity level higher are the chances.
• Richter Magnitude Scale: These range from 1.0 to 9.0 and higher. Earthquakes with magnitude 4.9 and lower do not generally cause damage. The ones with Richter magnitude 5.0 to 5.9 are considered moderate in nature. Lastly, magnitudes of 6.0 to 9.0+ cause extreme destruction.
So, the places that are classified in zone 5 are the most prone to earthquakes.
2) Kashmir valley
4) Western and Central Himalayas
5) North and Central Bihar
6) Raxaul, Bihar
7) Rann of Kutch in Gujarat
8) Andaman and Nicobar Islands
10) Patan and Koynanagar in Maharashtra
11) All northeastern states (Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura)
12) Sundarbans forest
14) Majha, North Punjab
15) Western Uttar Pradesh
16) Jalpaiguri and Malda division in Bengal

Is Tamil Nadu at risk of an earthquake?
As per NIDM (National Institute of Disaster Management) Tamil Nadu falls in the moderate risk zone i.e zone 3. Some other states like Maharashtra and Bihar also fall in zone 3 which have seen some huge earthquakes in the past. These are natural calamities and one can take precautions but can't predict mother nature's response.Helpful 4
