The Crescenta Valley Sheriff's Station went into disaster mode Thursday, if only for practice.
As part of the Great California Shakeout — with more than 7 million participants statewide, the nation's largest earthquake safety exercise — the station drilled for a magnitude-7.0 earthquake.
The exercise included a run-through of station evacuation, activation of its Emergency Operations Center and review of individual responsibilities there and in the field.
It all started at 10:21 a.m. with participants reacting to Capt. Dave Silversparre's announcement that a faux-quake had begun.
"Basically it's drop, cover and hold on," explained Sgt. Mike Brandoff of what event organizers, the Earthquake Country Alliance, advise all Californians to do in the event of a temblor.
The Earthquake Country Alliance is a group of government, public-safety and academic organizations that formed to promote quake safety in 2003 on the anniversary of the Jan. 17, 1994, Northridge Earthquake, which registered 6.7 on the Richter scale.
