REGIONAL VIEW

Bangladesh sits at the convergence of the Indian, Eurasian and Burma plates — one of the most seismically complex regions on Earth.

Most significant recent event

21 November 2025 — Narsingdi–Dhaka Earthquake

Magnitude M 5.5 (USGS) · M 5.7 (BMD)

Local time 10:38:26 BST

Epicentre Madhabdi, Narsingdi

Depth ~10 km (shallow)

Distance from Dhaka ~33 km west-southwest

Duration 26 seconds

Max intensity MMI VI — Strong

Aftershocks 4 recorded (M3.3 – M4.3)

A Friday-morning quake with epicentre near Madhabdi in Narsingdi struck close enough to the capital to produce the strongest shaking Dhaka has felt in living memory. Buildings swayed for nearly half a minute; in Old Dhaka, a five-storey building's railing collapsed into Koshaituli, killing three pedestrians. Factories in Gazipur evacuated chaotically. Felt as far as Kolkata, more than 325 km away.

Light · USGS

Dhaka, Dhaka Division

Aftershock-class event with epicentre near central Dhaka at 10 km depth. Came two weeks after the November 21 main shock; raised renewed alarm in already shaken neighbourhoods.

[ Chapter II ]

Three zones, one fragile geography.

§ 02 / 04

ZONE III · HIGH RISK

Northern & Eastern Belt

Encompassing Sylhet, Mymensingh, Rangpur and the northern Chittagong Hill Tracts. Closest to the Indo-Burma subduction front and the Dauki Fault — capable of magnitude 8+ events.

Peak Ground Acceleration0.36 g
Population at risk~32M
Key faultDauki

ZONE II · MODERATE

Central Plains

Dhaka, Tangail, Comilla and surrounding alluvial plains. Soft sediment amplification multiplies shaking intensity. Madhupur Fault runs through the region.

Peak Ground Acceleration0.28 g
Population at risk~50M
Key faultMadhupur

ZONE I · LOW

Southwestern Region

Khulna, Barisal, the Sundarbans delta. Distance from active faults reduces direct risk, but liquefaction of waterlogged soils remains a concern during distant strong events.

Peak Ground Acceleration0.20 g
Population at risk~35M
Key concernLiquefaction

[ Chapter III ]

When the ground speaks, you listen.

§ 03 / 04

Before

Secure heavy objects Anchor bookshelves, cabinets and water heaters to wall studs. Latch cupboard doors.

Map your safe spots Identify sturdy interior walls, under solid tables, away from windows. Practice with family.

Prepare a go-bag Water, dry food, torch, radio, first aid, photocopies of ID, cash. Keep near the exit.

During

Drop, Cover, Hold On Get down on hands and knees. Cover head and neck. Hold on to a sturdy shelter until shaking stops.

Stay where you are Do not run outside during shaking. Most injuries occur from falling debris when people move.

If outdoors Move away from buildings, power lines and trees. Drop to the ground in an open area.

After

Expect aftershocks Smaller follow-up tremors can occur for days or weeks. Be ready to drop, cover and hold again.

Check for hazards Smell for gas leaks. Inspect electrical wiring. Avoid using elevators until inspected.

Listen for official updates Tune to BTV, BBC Bangla, or trusted local radio. Avoid spreading unverified social media reports.
