Earthquake of 3.7 Magnitude Hits Mizoram, No Casualties Reported

KKN Gurugram Desk | An earthquake of 3.7 magnitude struck Mamit district in western Mizoram on Sunday, causing mild tremors across the region. The earthquake, which occurred at a depth of 10 kilometers, sent residents rushing out of their homes in panic. According to Mizoram’s Disaster Management Authority, there have been no immediate reports of damage to life or property.

This earthquake marks the second seismic event in the Northeastern region within four days. On February 27, a moderate 5.0 magnitude earthquake hit Morigaon district in Assam, with tremors felt across Guwahati and nearby areas.

Frequent Earthquakes in the Northeastern Region

According to the National Center for Seismology (NCS), the Northeastern region of India is one of the most earthquake-prone zones. The region falls under Seismic Zone VI, making it highly vulnerable to frequent seismic activity.

Key Facts About Earthquake Activity in Northeast India:

• The region experiences more than one earthquake per week.
• Most earthquakes in the area register between 3.0 to 4.0 magnitude.
• States like Assam, Mizoram, Manipur, and Meghalaya frequently experience mild to moderate tremors.
• Due to frequent seismic activity, authorities have encouraged the construction of earthquake-resistant buildings.

The latest earthquake in Mizoram highlights the seismic vulnerability of the region and the need for continuous monitoring and disaster preparedness.

Historical Earthquakes in Northeast India

The Northeastern region of India has witnessed several major earthquakes over the decades, some of which caused widespread devastation.

1. The Great Assam Earthquake of 1950 (Magnitude: 8.7)

One of the most devastating earthquakes in Indian history, the 1950 Assam earthquake recorded a magnitude of 8.7. The tremors were so powerful that they altered the course of the Brahmaputra River, impacting the commercial hub of Guwahati.

2. The 1988 Earthquake (Magnitude: 6.5)

A strong earthquake struck the Northeastern states of Assam and Arunachal Pradesh in 1988, causing over 200 fatalities. The tremors were widely felt across the region, triggering landslides and building collapses.

3. The 2011 Sikkim Earthquake (Magnitude: 6.9)

In 2011, a powerful earthquake measuring 6.9 magnitude hit Sikkim and parts of West Bengal, leading to over 100 casualties. The disaster left thousands homeless and caused significant damage to infrastructure.

4. The 2017 Tripura Earthquake (Magnitude: 5.7)

A moderate earthquake of 5.7 magnitude struck Dhalai district in Tripura, about 20 km northeast of Ambassa, causing panic among residents. Fortunately, no major casualties were reported.

The recurring seismic activity in the Northeast has forced disaster management agencies to conduct regular earthquake preparedness drills and awareness campaigns.

Why is Northeast India Prone to Earthquakes?

The Northeastern region of India lies in the seismically active zone of the Himalayas, making it one of the most earthquake-prone areas in the country.

Factors Contributing to Frequent Earthquakes in Northeast India:

1. Tectonic Plate Movements

   • The region is situated near the boundary of the Indian and Eurasian tectonic plates.
   • Continuous collision and subduction of these plates result in frequent tremors.

2. Himalayan Seismic Belt

   • The Himalayan belt is known for high seismic activity due to continental drift and stress accumulation.

3. Subduction Zones

   • The presence of active subduction zones near the Indo-Burma region leads to regular seismic disturbances.

Due to these factors, earthquake-resistant construction and disaster preparedness measures are essential for mitigating the impact of future earthquakes.

How to Stay Safe During an Earthquake?

Given the frequent seismic activity in Northeast India, it is crucial for residents to follow earthquake safety guidelines.

Precautionary Measures Before an Earthquake

✔ Secure heavy objects and ensure they are properly anchored.
✔ Identify safe spots in your home, such as under sturdy furniture.
✔ Keep emergency kits with essential supplies, including food, water, and medical aid.
✔ Stay informed about seismic activity through official government updates.

What to Do During an Earthquake?

✔ If indoors, drop, cover, and hold on to a sturdy table or desk.
✔ Stay away from windows, doors, and heavy furniture that may topple.
✔ If outdoors, move away from buildings, trees, and power lines.
✔ If driving, stop in a safe open area away from overpasses and bridges.

Steps to Take After an Earthquake

✔ Check for injuries and provide first aid if necessary.
✔ Avoid using elevators as aftershocks can cause them to malfunction.
✔ Inspect your home for gas leaks, electrical damage, and structural cracks.
✔ Stay alert for aftershocks and follow official guidelines for evacuation.

Preparedness is key to minimizing damage and ensuring safety during an earthquake.

Government Initiatives for Earthquake Preparedness in Northeast India

The Indian government and disaster management authorities have been taking proactive steps to enhance earthquake preparedness in the Northeastern states.

Key Measures Implemented:

✔ Installation of Earthquake Early Warning Systems in seismic-prone areas.
✔ Construction of Earthquake-Resistant Buildings in urban and rural zones.
✔ Regular Awareness Programs for schools, offices, and local communities.
✔ Deployment of National Disaster Response Force (NDRF) for quick rescue operations.

The continuous monitoring of seismic activity by National Center for Seismology (NCS) helps in issuing timely alerts and reducing potential risks.

The recent earthquake in Mizoram and the frequent seismic activities in Assam, Manipur, and Meghalaya highlight the need for strict disaster preparedness in Northeast India. While the region has historically witnessed devastating earthquakes, better infrastructure, awareness, and rapid response systems can help reduce the impact of future disasters.

With earthquake-resistant construction, government initiatives, and public awareness, Northeast India is gradually improving its preparedness for seismic events. However, constant vigilance and proactive measures are necessary to ensure the safety of millions of people living in this high-risk zone.
