A gas explosion in Remedios de Escalada, a district of Lanús in Greater Buenos Aires, killed one person and injured about 30 on the morning of Friday, 13 November 2026. The blast at 10:52 hit the corner of Coronel Beltrán and Del Valle Iberlucea streets, Infobae, an Argentine daily, reported on 13 and 14 November.
The gas utility MetroGAS says it received an emergency call about a damaged pipe at 9:44 and that a technician arrived at 10:04. Corporate affairs director Alejandro Di Lázzaro gave that timeline to TN, an Argentine TV channel, as Infobae reported on 13 November.
What We Know
Claudio Arale, director of civil defence in Lanús, said a tunnelling machine used by the subcontractor Exgadet damaged a gas distribution pipe during network renewal works, Infobae reported on 13 November. The gas supply was cut at 2:10 a.m. on Saturday, Infobae reported on 14 November.
Five people remain seriously hurt, with burns covering 40% to 90% of the body, and 13 patients are in hospital, Infobae reported on 14 November. Two of the five are in intensive care without ventilators, and the condition of two workers was still pending.
Everyone living or working within 100 metres (about 330 feet) of the blast was evacuated, Infobae reported on 13 November.
Who Is Responsible Is Still Disputed
Prosecutor Yanina Estévez ordered two MetroGAS executives held for questioning, a step Argentine prosecutors call a “demora”, Infobae reported on 13 November. Arale said the prosecutor’s office had requested their detention over breaches of emergency protocols, and Estévez clarified that no one has been arrested.
“Si se hubieran cumplido los protocolos de emergencia, esta situación se podría haber evitado,” Arale said, meaning the blast could have been avoided if the protocols had been followed. MetroGAS said it had not yet been notified of any detention request, Infobae reported on 13 November.
Estévez, who heads local criminal investigation unit No. 6, is to establish the responsibility of MetroGAS and Exgadet, a contractor hired for the network works, according to Infobae on 14 November. The national gas and electricity regulator (Ente Nacional Regulador del Gas y la Electricidad) said it is monitoring the case with MetroGAS and will put its results at the disposal of the courts, Infobae reported on 14 November.
Under Argentine law, suspects are presumed innocent until a court rules.
Why It Matters
The people most affected are residents of the evacuated blocks, the injured workers and families still waiting to learn who the dead person is. With about 30 people hurt and an exclusion zone of 100 metres, the case will test whether the subcontractor’s work and the utility’s emergency response followed the rules.
What Is Not Known
The dead person has not been identified. Infobae reported on 13 and 14 November that no one is still missing, after one person was found disoriented and another report proved a false family alarm, while a report in Página/12, an Argentine daily, under a 14 November address is headlined “one dead and two missing”.
The official cause, the exact order of the emergency response and any charges are not public. We found no announced dates for hearings or for any regulator findings.
