The tsunami watch in effect this morning for the Queen Charlotte Islands/Haida Gwaii and the Alaska, BC and Washington coasts was cancelled just before 7:00 am.
A small tsunami wave was generated by an earthquake north of Japan at 3:14 am, and there was a possibility of a wave arriving on the west coast and Langara Island around 10 am. Officials watched the situation closely and RCMP on the Queen Charlottes were on duty by 5:30 am.
Areas in Alaska were issued a tsunami warning, while from the Queen Charlottes/Haida Gwaii to Washington, a tsunami watch was in effect between 5:30 am and 7:00 am. Both are now cancelled.
The 8.1 magnitude earthquake in Japan caused a tsunami less than a metre high in northern Japan.
Tsunamis are a series of waves which could be dangerous for several hours after the arrival of a first wave.
