Oslo water usage surges after rare earthquake

A sudden spike in Oslo’s water consumption followed the strongest earthquake in over 20 years, with officials suggesting residents likely woke up and began using water after the tremor, Dagbladet reports.

The city’s water and sewage agency observed an unusual pattern in real-time data: consumption briefly dropped as the quake struck, then surged well above normal levels for a Sunday morning.

“Everything stopped, and people checked what was happening,” said Andreas Normann, senior duty officer at Oslo’s water and sewage agency. “Many may have been woken by the shaking, got up, and started using water—perhaps taking showers afterward.”

Initially, the agency feared the spike could indicate a major leak. However, the drop in usage immediately after the quake ruled that out, Normann explained. The increase was also evenly distributed across all city districts, further confirming no infrastructure damage.

The system operates continuously, monitoring consumption 24/7 to detect anomalies like leaks. Normann noted that while earthquakes are rare in the region, the agency remains vigilant after any unusual event.

“I felt it clearly,” he added. “At first, I thought a neighbor might be renovating, but I quickly realized what it was.”
