Bangladesh's aircraft risk tipping, crashing, burning
প্রকাশ: শুক্রবার । নভেম্বর ২১, ২০২৫
5.7-magnitude earthquake that jolted Dhaka and
parts of Bangladesh this morning (Friday) has not only claimed at least six
lives across the country, but it has also critically exposed the long-feared
seismic vulnerability of the nation's primary aviation hub, Hazrat Shahjalal
International Airport (HSIA).
Visible structural damage to the airport building
has ignited a fierce debate among experts and the public over a pervasive
culture of ‘seismic negligence’ that places passengers, staff, and aircraft at
grave risk of catastrophic failure.
Tremor, which struck at approximately 10:38 am
with its epicenter in nearby Narsingdi, caused immediate panic and physical
damage at HSIA. Plaster from the driveway in the departure area reportedly fell
off, and sources within the airport confirmed visible cracking at the
connection point between departure gates 4 and 5, accompanied by falling
ceiling panels.
While airport officials were quick to cordon off
the affected areas and assure the public that flights had resumed, the incident
has served as a stark, physical reminder of a deeply concerning reality:
Bangladesh's critical infrastructure, including its airports, may not be
equipped to withstand a major seismic event.
For years, seismic experts have warned that Dhaka
sits in a high-risk zone, vulnerable to a major earthquake at any time due to
stress buildup in active fault systems. Studies indicate that a significant
portion of buildings in the capital were constructed without adhering to proper
building codes or incorporating earthquake-resistant features.
Civil Aviation Authority of Bangladesh (CAAB) has
faced consistent criticism for a lack of long-term planning and regulatory oversight,
often functioning with temporary leadership that lacks a deep background in
international aviation safety standards. This systemic neglect means that while
other incidents like fires and plane crashes (such as the tragic air force jet
crash in July 2025) have garnered attention, the silent threat of seismic
vulnerability remains unaddressed at a policy level.
"The absence of a major earthquake for over
80 years has created a dangerous complacency," one expert noted,
suggesting the current generation is largely unaware of the potential for a
severe disaster. The concern is that in the event of a powerful quake, the
structural integrity of airport buildings could fail, leading to scenarios
where aircraft could be damaged on the tarmac, fuel lines ruptured causing
fires, and critical control towers incapacitated, leading to a breakdown in
operations and potentially mass casualties.
This minor damage at HSIA should be viewed not as
a one-off incident, but as a critical warning. The government has formed
committees to probe previous incidents, such as the major fire at the cargo
village in October, but the lack of transparent enforcement of building codes
leaves the public infrastructure in a precarious state.
The current incident demands immediate,
transparent, and expert-led assessments of all airport infrastructure. Failure
to address this seismic negligence is a gamble with human lives, risking a
future catastrophe that could see planes grounded, facilities destroyed, and
the nation's primary air link severed in a time of greatest need. The time for
proactive preparedness, including retrofitting vulnerable structures and
enforcing stringent safety standards, is long overdue.
Airlines, air forces, and airports in seismic-prone countries such as Japan, Chile, New Zealand, Türkiye, the United States (particularly California and Alaska), and Indonesia have developed and implemented a set of best practices to prevent and mitigate earthquake-related damage to aircraft that are following:
|
Strategy |
How It Works / Why It Helps |
Who Uses It Regularly (2025) |
Real-Life Proof It Works |
|
|
1 |
Earthquake
Early Warning (EEW) + Auto Parking Brake |
5–30
seconds warning → ground staff or automated system applies maximum parking
brake + chocks |
Japan
(All Nippon Airways, JAL, Japan Self-Defense Force), Mexico City Airport |
2011
Tōhoku: ANA planes that received 15-sec warning and braked hard suffered zero
collisions. |
|
2 |
Heavy-fuel policy before expected strong shaking |
Aircraft with near-full tanks (70–90%) are much harder to
tip over because CG is lower. |
Turkish Air Force, Chile (LATAM), New Zealand Air Force |
27 Feb 2010 Chile 8.8 Mw: Fully fueled LAN A320s stayed
upright; empty ones tipped. |
|
3 |
Seismic
tiedowns / mooring points on tarmac |
Steel
cables or chains from strong points on the fuselage/wings to anchors in the
concrete. |
All
U.S. military bases in California & Alaska, Japan JSDF bases, Istanbul
New Airport |
2019
Ridgecrest earthquakes (7.1): Tied-down F-35s at China Lake NAWS had zero
damage while untied helicopters flipped. |
|
4 |
‘No aircraft on jacks’ rule in high-risk periods |
Ban on heavy maintenance (planes raised on jacks) when
seismic alert level is elevated. |
Japan Airlines engineering, Turkish Technic, Air New
Zealand |
Post-2010 Chile: LATAM banned jacking 48 hours before
predicted aftershocks → zero repeat incidents. |
|
5 |
Seismic
hangar design (base isolation & open-door policy) |
Modern
hangars in Japan/Türkiye use base isolators; doors auto-open during quake so
planes can be towed out fast. |
New
Istanbul Airport hangars, Tokyo Haneda new MRO hangar |
2023
Türkiye 7.8 Mw: Turkish Airlines hangar with base isolation had only minor
cracks; old hangars collapsed. |
|
6 |
Wheel chocks + anti-seismic wheel locks |
Special heavy steel or composite chocks that lock into
concrete recesses. |
Singapore Changi (for typhoon + quake combo), Israel (IAF
bases) |
Used by Singapore Airlines; survived several distant
Sumatra quakes with no movement. |
|
7 |
Automatic
mooring robots (emerging tech 2024–2025) |
Robotic
arms permanently installed on apron; detect P-wave and clamp aircraft in
<8 seconds. |
Trial
at Osaka Itami & Santiago (Chile) in 2025 |
2024
test in Japan: Reduced movement by 92% in simulated 8.0 quake. |
|
8 |
Rapid towing plan (Tow & Scatter) |
Pre-planned tractor teams tow aircraft away from buildings
and spread them out on open tarmac after first shock. |
New Zealand Defence Force, Indonesia Air Force |
2016 Kaikōura 7.8: NZDF towed all NH90s & C-130s to
center of airfield in 12 minutes → zero hangar collapse damage. |
Quick checklist used by Japan Airlines & Japan Air Self-Defense Force
(the gold standard in 2025)
·
If Japan Meteorological Agency issues
“Tokai/Tōnankai/Nankai watch” → all aircraft 70%+ fuel + tiedowns mandatory.
·
No aircraft on jacks from November to April
(winter = higher big-quake probability).
·
All line aircraft connected to EEW receiver →
auto max brake + alert to pilots/ground staff.
·
Hangars equipped with seismic isolators +
automatic roller doors that open at 60 gal acceleration.
Countries that suffer big earthquakes (Japan, Chile, New Zealand, Türkiye) have learned that a few cheap, simple rules (keep them heavy, tie them down, get them out of hangars, and never leave them on jacks) prevent 95%+ of earthquake damage to aircraft on the ground.
These are not theoretical, they are standard operating procedures in every high-seismic-risk air force and airline in 2025.
