The January Blackout in Southwest Berlin
In early January, a significant power outage hit affluent neighborhoods in southwest Berlin. The sabotage was claimed by the self-styled Volcano Group, which posted an online statement dismissing sympathy for residents. Federal prosecutors have opened an investigation and will interview a resident, identified as Thomsen, about the incident.
Background, Actors, and the Loose Left-Wing Network
The Volcano Group name has appeared over the past decade in attacks on rail lines, power infrastructure, and the Tesla gigafactory site. The German Interior Ministry links at least 13 incidents to the label. Investigators describe the label as a loose identifier used by a fragmented scene of left-wing activists, with ideological writers and small operational cells of friends or siblings.
Timeline and Impact
- September 2025: Two power pylons in Johannisthal were set on fire, targeting the Adlershof technology park; tens of thousands lost power for days. An online claim read “Some anarchists.”
- January 2024: Blackout in southwest Berlin, claimed by the Volcano Group.
- 2014-2023: Multiple sabotage incidents on rail lines and the Tesla gigafactory, all linked to the Volcano Group label.
Official Statements & Responses
German authorities say the Volcano Group functions as a label for a loosely coordinated activist scene, complicating law-enforcement. The Interior Ministry reiterated its count of 13 attacks and announced tighter monitoring of left-wing publications that detail grievances and sabotage methods. The federal prosecutor confirmed a criminal investigation and scheduled interviews with affected residents.
Criticism & Opposition
Security officials criticize the network’s ad-hoc coordination, noting that its fragmented structure hampers prevention and attribution. Analysts stress the difficulty of identifying individuals when the label is reused across unrelated incidents.
Conflicting Reports & Gaps
Sources disagree on whether the Volcano Group is a single organization or merely a shared label. The Interior Ministry treats it as a cohesive entity for statistics, while investigators describe it as a “scene” without formal hierarchy. The perpetrators of the January blackout remain unidentified.
