Each year schools, houses, businesses and many public places participate in the world's largest earthquake drill ShakeOut.
Happening the third Thursday of every October, this year's ShakeOut will kick-off at 10:19 a.m. on Oct. 19.
According to The California Geological Survey there are thousands of faults in California, 500 of which are active and dangerous.
“California is earthquake country,” said Glenn Pomeroy, CEO of the California Earthquake Authority (CEA). “We need to ask ourselves whether we’re prepared to survive and recover when the next damaging earthquake strikes—and if we aren’t, we need to take action now to change that.”
