Release of Douglas Channel tsunami report postponed to November 16

The Northern Gateway Joint Review panel has allowed the Department of Fisheries and Oceans and Natural Resources Canada to delay a report on historic tsunamis and a possible fault line on Douglas Channel until November 16, 2012.

The report was scheduled for release on October 31.

In a ruling released by the JRP on November 1, the panel noted:

In Ruling no. 105 dated 24 September 2012, the Panel stated that the Department of Fisheries and Oceans (DFO) could provide “modelling of the potential wave heights and speeds that may  have resulted from two previously unrecognized submarine slope failures in the Douglas  Channel” (Modelling) and that it should do so by 31 October 2012. The letter from Justice Canada seeks an extension to 16 November 2012 as DFO “requires additional time to complete the peer review and approval processes related to this additional written evidence.”
The Panel believes the Modelling to be relevant, as noted in Ruling no. 105. The Panel is also ofthe view that there is unlikely to be any undue prejudice to any party by permitting its filing to be delayed to 16 November 2012.

Accordingly, the Federal Government Participants’ motion is granted and DFO is permitted to file the Modelling on or before 16 November 2012

A preliminary report was released in early September and outlined evidence of major slope failures on the islands in Douglas Channel and also a possible fault line along part of the Douglas Channel.

The Department of Justice filed the request with the JRP on Monday Oct. 30, 2012, less than 48 hours after a major earthquake of magnitude 7.7 struck off Haida Gwaii just after 8 p.m. Pacific Daylight Time, on Saturday Oct. 27, shaking much of northern BC. There have been numerous aftershocks since the main quake.
