Kolkata Earthquake Today (Feb 27, 2026): Mid-Day Tremors Rattle the City

Kolkata’s usual post-lunch lull was suddenly interrupted today as a sharp earthquake shook homes, offices, and high-rises across the city. What began as a faint vibration quickly turned into noticeable swaying—enough to send residents rushing outdoors and social media into overdrive.

Here’s everything we know so far.

Time of Tremor: ~1:22 PM IST
Status: Ongoing updates

Earthquake Details: Magnitude, Epicenter & Impact

• Estimated Magnitude: 5.3–5.5
• Epicenter: Southwestern Bangladesh (Khulna–Dhaka region)
• Depth: Approximately 10 km (shallow)
• Tremor Duration in Kolkata: 5–10 seconds
• Worst Affected Areas in the City: New Town, Rajarhat, Salt Lake, Sector V high-rises

Because the quake was shallow, the shaking felt sharper and more intense—even though the epicenter was outside India.

What Kolkata Experienced This Afternoon

The tremors were brief but strong enough to be felt across multiple neighborhoods.

• Office buildings in Sector V saw employees evacuating through stairwells.
• Residents in New Town and Rajarhat high-rises reported noticeable swaying.
• Several households described ceiling fans and hanging lights shaking visibly.
• In older North Kolkata buildings, residents stepped outside as a precaution.

Within minutes, WhatsApp groups and social feeds were flooded with “Did you feel that?” messages. Google’s earthquake alerts followed shortly after.

Why Did the Tremor Feel Strong in Kolkata?

Although the epicenter was in Bangladesh, Kolkata’s geographical makeup played a major role in amplifying the shaking.

The city is built on alluvial and marshy soil, which tends to intensify seismic waves. When earthquake energy passes through softer ground, it can feel stronger compared to areas built on solid rock. That’s why even a moderate quake can cause significant swaying in high-rise buildings.

Are Aftershocks Possible?

Aftershocks are common following moderate earthquakes. While none of significant magnitude have been officially confirmed in Kolkata yet, experts generally advise remaining cautious for the next few hours.

Earlier tremors were also reported in parts of eastern India earlier today, adding to heightened public sensitivity.

What You Should Do After an Earthquake

Here are immediate safety steps residents should follow:

Stay Outdoors Briefly

If you evacuated, remain in open spaces for some time in case of aftershocks.

Inspect Your Building

Look for:

• Fresh cracks in walls or ceilings
• Tilting structures
• Water leakage or gas smell

If you live in older heritage homes, conduct a careful inspection.

Avoid Rumors

Rely only on verified updates from official agencies. Do not circulate unconfirmed messages about structural collapses or disasters.

Keep Emergency Contacts Ready

Have local emergency numbers saved and accessible.

Damage & Casualty Update (As of Now)

At the time of writing:

• No major injuries reported in Kolkata
• No large-scale structural damage confirmed
• Mostly minor panic and temporary evacuations

Authorities are monitoring the situation closely.

Final Thoughts

Today’s earthquake was a reminder that eastern India, though not the country’s most active seismic zone, is not immune to tectonic movement. Preparedness—not panic—is the best response.

If you felt the tremor, take a moment to check on family and neighbors. Stay alert, stay informed, and stay calm.
