THE CASTAWAYS ARE SHAKEN -- LITERALLY -- WHEN THEY EXPERIENCE A MAJOR EARTHQUAKE, ON "SURVIVOR: VANUATU�ISLANDS OF FIRE," THURSDAY, OCT. 14, ON CBS

"Earthquakes and Shake Ups" -- A major earthquake rocks the island, on SURVIVOR: VANUATU -- ISLANDS OF FIRE, Thursday, Oct. 14 (8:00-9:00 PM, ET/PT), on the CBS Television Network.

While the earthquake rattles the castaways' nerves, both tribes receive an unexpected visit from Vanuatu natives who come bearing a message with great consequences for all tribe members. A trip for one tribe proves cathartic and makes one castaway, in particular, very happy. At the Immunity Challenge, one castaway is caught by a fellow tribe member as they try to secretly communicate with a member of the opposing tribe.

And, the sixth member is voted out of the tribe.
