Advisory: Stanford Testing Emergency Sirens

PALO ALTO, CA — Palo Alto and other communities in close proximity to Stanford University should note that the university is testing its outdoor warning sirens between noon and 12:30 p.m. Thursday, Oct. 19. The alarm is part of the annual "AlertSU," test of Stanford's mass notification system used for emergencies.

Activation of the outdoor warning system Thursday will begin with an audible tone lasting approximately 60 seconds. Then a verbal message will be heard through seven sirens at various campus locations. The sirens will be audible throughout the campus and may also be heard in parts of the surrounding communities including Palo Alto, Menlo Park and Los Altos, according to the university.
