The scene of an emergency response to a possible underground vault fire in downtown San Francisco on Thursday morning has been cleared, fire officials announced.

At about 6 a.m., the San Francisco Fire Department responded to reports of a vault fire in the 100 to 200 block of California Street, fire officials said on social media.

Soon after, fire officials said four PG&E vaults “experienced eruptions,” which led to a power outage, closed streets, evacuations and shelter-in-place orders.

The immediate area was evacuated and a shelter-in-place order was expanded to include 100 to 300 California Street and 100 to 300 Front Street.

SFFD announced at a little after 11 a.m. that the emergency response was over and streets were back open to traffic.

No injuries were reported.

A spokesperson for PG&E said the company responded to “an underground equipment hazard” that was caused by “an issue related to an underground cable” and that as of 9 a.m., only one customer was without power.
