Power Cable Fire Suspected in Oslo Explosions, Evacuations Underway
Table of Contents
A likely fire in an underground power cable triggered a series of minor explosions and methane gas buildup in Oslo, Norway, prompting evacuations and disruptions to train service on Saturday, December 13. Authorities report no injuries at this time, but investigations are ongoing to determine the full extent of the incident.
Trains Resume Service After Power Outage
Train service in the affected area resumed at 10:45 am local time after a power outage caused by the incident.According to operations manager Roger Aaser, “The power is back and the trains are running as normal again.” The disruption stemmed from an incident connected to the power outage, with emergency services initially responding to reports of accumulating methane gas.
Explosions Lift Manhole Covers, Prompt Evacuations
The series of explosions, described as minor, resulted in four manhole covers being lifted from the street. A duty manager at the 110 central in the South-East, speaking to VG, explained that the explosions occurred within the pipe system. “There have probably been a fire in a power cable that is under the pipe system,” the manager stated. “When the big, thick pipes burn, gas builds up. That gas is heavier than air, and thus stays put. Then when the power comes back on, the gas is ignited. That is probably the cause of the explosion.”
Investigation Focuses on Underground Infrastructure
Currently, the fire brigade and police are collaborating with plumbers and electricians to investigate the cause and scope of the incident. While the extent of the explosions is believed to be limited, some homes in the Sporveien area are being evacuated as a precautionary measure while the investigation continues, according to Aaser.
Despite the explosions, authorities have confirmed there is no damage to buildings or the road network. A senior official with the fire service indicated that the pipe system is highly likely robust enough to withstand such events.
