When a recent earthquake rocked Napa Valley and the broader San Francisco area overnight, radio broadcasters across the region quickly went into wall-to-wall coverage. CBS Radio’s KCBS-AM San Francisco aired uninterrupted reports with emergency information and developments, while Cumulus Media’s KGO-AM also went wall-to-wall with updates on the damage. TV broadcasters also quickly responded. The San Francisco Chronicle reports CBS-owned KPIX-TV San Francisco carried KCBS-AM coverage until the station could get reporters into the studio for a live broadcast and up to the Napa Valley where the earthquake was felt the strongest. ABC-owned KGO-TV San Francisco quickly brought in their news anchors to provide emergency updates and show images of the damage as it became available.
