Telangana Hit with Second-Biggest Earthquake in 55 Years: Why Tremors Are Rare Here

Telangana experienced a rare seismic event today, as a magnitude 5.3 earthquake struck Mulugu district, marking the second-largest earthquake in the region in 55 years. The tremors, felt around 7:27 a.m. on Wednesday, originated at a depth of 40 kilometers, according to the National Center for Seismology (NCS).

While no major damages or casualties have been reported so far, the quake left many residents shaken and wondering why such an event occurred in a region not typically known for seismic activity.

What Happened?

The earthquake, with its epicenter near Mulugu, about 200 kilometers from Telangana’s capital Hyderabad, startled many who were just beginning their day. Several residents reported furniture shaking and household items rattling, but thankfully, no large-scale destruction was observed.

The tremors were strong enough to be felt in nearby districts, and many residents took to social media to share their experiences. Authorities have advised people to stay calm and vigilant, as aftershocks may follow.

Why Are Earthquakes Rare in Telangana?

Telangana lies on the Deccan Plateau, one of the oldest and most stable geological formations in India. The region is considered to have relatively low seismic activity because it is located far from the tectonic plate boundaries that usually generate earthquakes.

India is divided into four seismic zones (Zone II to Zone V), with Zone II being the least active and Zone V the most. Telangana falls primarily in Zone II, indicating a very low probability of significant seismic activity.

What Caused the Earthquake in Mulugu?

Despite being a low-risk zone, certain geological factors can occasionally trigger earthquakes in stable regions like Telangana. These include:

Intraplate Stress: Earthquakes within tectonic plates (as opposed to along plate boundaries) can occur due to accumulated stress over millions of years. Such intraplate quakes are rare but not impossible.
Local Faults and Weak Zones: Geological faults in the region, though dormant for long periods, can occasionally reactivate under certain conditions, releasing pent-up stress.
Human Activities: While there’s no direct evidence linking this quake to human activities, factors like mining or large-scale reservoir constructions (e.g., dams) are known to induce seismicity in some areas.

Telangana’s Earthquake History

The Mulugu earthquake is the second-largest recorded in Telangana in over half a century. The largest earthquake occurred in 1969, when the region experienced a quake measuring 5.7 on the Richter scale. Such events are extremely infrequent, with most past quakes being minor tremors that caused little to no damage.

Preparedness and Response

Telangana’s state disaster management authorities have reassured the public that there is no cause for panic. However, this event serves as a reminder of the importance of being prepared, even in regions with low seismic risks.

Tips for Earthquake Safety:

Identify safe spots in your home, such as under sturdy furniture.
Avoid using elevators during tremors.
Keep an emergency kit with essentials like water, food, and first-aid supplies.

Conclusion

Today’s earthquake in Mulugu was a rare event, reminding us that even geologically stable regions are not immune to nature's unpredictability. While the Deccan Plateau offers a measure of security from frequent seismic activity, occasional tremors can still occur due to various geological factors.

As Telangana recovers from this surprise event, it’s a good opportunity for authorities and residents alike to review and strengthen disaster preparedness measures to ensure safety in the face of such unexpected occurrences.
