A series of underground vault eruptions in downtown San Francisco prompted evacuations, an expanded shelter-in-place order and a power outage Thursday morning, fire officials said.<\/p>\n
The San Francisco Fire Department responded just after 6 a.m. near California and Front streets after smoke was reported coming from several underground vaults. Earlier reports had described the incident as a vault fire. <\/p>\n
