洛杉矶郡火灾官员周二发布的调查报告确认，2025年致命的Eaton火灾系由南加州爱迪生公司一座停用电塔的设备故障所引起[1]。该火灾造成19人死亡，摧毁或损坏超过9000栋住宅和商业建筑，烈火蔓延22平方英里[1]。
调查发现，两次快速连续发生的电弧事件是火灾的直接原因[1]。这两次电弧事件在12秒内迅速发生，导致物质从电塔落到地面，在极端天气条件下引燃干燥的草和灌木丛[1]。Pasadena的一名居民于1月7日拨打911报警，描述发现"高压电塔基部10英寸×10英寸的火"[1]。死者中18人住在West Altadena地区[1]。消防员用了近一个月才扑灭火灾[1]。此次调查历时18个月[1]。
南加州爱迪生公司发言人Kathleen Dunleavy表示，公司"从一开始就认真对待公司在火灾起因中可能的角色"[1]。
Los Angeles County fire officials determined in a report released Tuesday that the deadly 2025 Eaton Fire was ignited by a malfunctioning de-energized electrical tower owned by Southern California Edison Company [1]. The investigation, which took 18 months to complete, found that two rapid electrical arc events occurring within 12 seconds caused material to fall from the tower to the ground, which then ignited dry grass and brush under extreme weather conditions [1].
The fire proved catastrophic in its scope and human cost. It claimed 19 lives, with 18 of the deaths occurring in West Altadena, and destroyed or damaged over 9,000 residential and commercial structures across 22 square miles [1]. Firefighters required nearly a month to extinguish the blaze [1]. A Pasadena resident first reported the fire on January 7 by calling 911 to describe a fire measuring 10 inches by 10 inches at the base of a high-voltage tower [1].
Southern California Edison Company spokesperson Kathleen Dunleavy stated the utility has "taken the role the company may have played in the fire's cause seriously from the outset" [1].
