A tree fell during the graduation ceremony at Diablo Valley College, injuring at least twelve people on Friday evening as attendees gathered to honor the Class of 2025, according to officials.

The incident occurred shortly before 7:00 p.m. near the football field, just as the commencement ceremony was coming to a close.

The Contra Costa County Fire Protection District reported that although the injuries were not life-threatening, significant emergency response was necessary.

Emergency crews were already on site as part of the school’s standard protocol and were able to quickly attend to the injured. 

College officials said that none of the injured individuals were graduating students, as most were around the main stage at the time of the incident.

Out of the approximately 12 people who were injured, officials said only three individuals sought additional treatment at a local hospital.

Diablo Valley College expressed regret over the incident during what was expected to be a celebratory evening.

A statement from the school emphasized their commitment to campus safety, expressing regret over the incident occurring during such an important event. They congratulated all 2,442 graduates and wished them joyful celebrations with their families that evening.

Officials said the cause of the collapse remains under investigation and gave no indications if the tree’s age or if weather played a role.

A nearby weather observation site, located outside of Oakland, indicated winds were gusting upwards of 30 mph around the time of the event.

Despite the unexpected event, officials said that the graduation ceremony was able to conclude, and school operations were not impacted.

“An evaluation of the circumstances surrounding this incident has begun and will continue in the days to come,” school staff stated.
