Dhaka earthquake risk: Gas leaks and fires could compound mass casualties
Synopsis
Key Takeaways
A major earthquake striking Dhaka, Bangladesh's densely packed capital, could unleash a cascade of secondary disasters — including large-scale fires ignited by ruptured gas pipelines and electrical short circuits — dramatically multiplying the death toll beyond structural collapse alone, according to a report by leading Bangladeshi newspaper The Daily Star.
Specialists cited in the report warn that fatalities in earthquake-hit urban areas rise sharply when fires break out in the aftermath, particularly where emergency response infrastructure is inadequate and populations are tightly concentrated.
How Utility Systems Become Hazards
Essential services — electricity, gas, and water — can rapidly transform into sources of catastrophic danger during a powerful tremor. Damaged electrical lines spark short circuits, ruptured gas mains ignite fires, and broken water supply networks cripple firefighting efforts precisely when they are needed most.
Dhaka is considered especially exposed because overhead electricity cables crisscross much of the city, while gas and water pipelines run beneath heavily congested roads and residential neighbourhoods. In a major seismic event, these interconnected systems could trigger a chain reaction of secondary disasters.
Expert Warning: Fire Is Among the Deadliest Secondary Effects
Mohammad Abu Sadeque, former Vice President of the Bangladesh Earthquake Society and Executive Director of the Centre for Housing and Building Research, told The Daily Star that fire is one of the most dangerous secondary effects of earthquakes in vulnerable cities.
According to Sadeque, post-earthquake fires most commonly originate from electrical short circuits. If a major tremor strikes during cooking hours, gas stoves become an additional ignition risk. During night-time hours, electrical faults remain the primary cause — and such fires can spread rapidly once underground gas pipelines rupture, allowing leaking gas to accelerate the flames.
Sadeque also cautioned that seismic events severely disrupt water supply systems: as pipelines fracture and water drains away, residents face acute shortages, making firefighting operations far more difficult while leaving households without stored water in immediate hardship.
He identified Dhaka, Sylhet, and Chattogram as cities at particularly elevated risk, given their extensive underground gas pipeline networks.
Mitigation Measures Recommended
Sadeque urged that fires caused by electrical short circuits can be significantly reduced by installing automatic shut-off devices at the main electrical connection of every building, enabling the power supply to be cut instantly during an emergency. He also stressed that hospitals must rely on early-warning alarm systems to give surgeons time to pause procedures and protect patients, and that oxygen cylinders must be securely anchored to prevent them from toppling during strong tremors.
State of Emergency Preparedness
Following the recent Narsingdi earthquake, Fire Service and Civil Defence Director General Brigadier General Muhammad Jahed Kamal told The Daily Star that a 60-member Special Rescue Team has been placed on standby at Purbachal to respond to emergencies. 'If any fire station becomes unable to operate due to an earthquake, this reserve team will be deployed,' he said.
Kamal added that the department is training 62,000 volunteers nationwide as part of earthquake preparedness efforts. Of these, 55,000 have already completed training, with refresher courses currently underway. He nonetheless cautioned that an earthquake of extremely high magnitude could still overwhelm the department's existing emergency response capacity, underscoring the urgency of broader structural reforms in urban disaster readiness.
