Narrative:
At XA45Z, was informed by zan that an aircraft at FL320 had reported moderate to severe turbulence over 56N 160W. I immediately turned on the seatbelt signs and made an announcement. I then told the flight attendant to be seated. Over 56N 160W, we encountered moderate turbulence. 3 flight attendants were injured. Diverted to anc and landed. Turbulence lasted about 15 seconds.
