Seismotectonics of Offshore British Columbia-Southeastern Alaska and Vicinity
The tectonics of the Pacific margin of North America between Vancouver Island and south-central Alaska are dominated by the northwest motion of the Pacific plate with respect to the North America plate at a velocity of approximately 50 mm/yr. In the south of this mapped region, convergence between the northern extent of the Juan de Fuca plate (also known as the Explorer microplate) and North America plate dominate. North from the Explorer, Pacific, and North America plate triple junction, Pacific:North America motion is accommodated along the ~650-km-long Queen Charlotte fault system. Offshore of Haida Gwaii and to the southwest, the obliquity of the Pacific:North America plate motion vector creates a transpressional regime, and a complex mixture of strike-slip and convergent (underthrusting) tectonics. North of the Haida Gwaii islands, plate motion is roughly parallel to the plate boundary, resulting in almost pure dextral strike-slip motion along the Queen Charlotte fault. To the north, the Queen Charlotte fault splits into multiple structures, continuing offshore of southeastern Alaska as the Fairweather fault, and branching east into the Chatham Strait and Denali faults through the interior of Alaska. The plate boundary north and west of the Fairweather fault ultimately continues as the Alaska-Aleutians subduction zone, where Pacific plate lithosphere subducts beneath the North America plate at the Aleutians Trench. The transition is complex, and involves intraplate structures such as the Transition fault. The Pacific margin offshore British Columbia is one of the most active seismic zones in North America and has hosted a number of large earthquakes historically. https://earthquake.usgs.gov/earthquakes/eventpage/us60007f42/region-info
Whew just got cleaning the sidewalk from that snow fall whopper and started to clean a spot for the driveway garbage can when my neighbour came over and said he measured over 14 inches (35.56 cm)
|Whew just got cleaning the sidewalk from that snow fall whopper and started to clean a spot for the driveway garbage can when … No I said the first night we had 18 inches before I went to bed and 24 at the front gate before we got the rain and after the rain it was 17 inches deep before I started shoveling yesterday morning at 06:00. ________________________________|
Thanks for clarifying, just gotta love those neighbours
My neighbour was struggling with trying to open her overhead garage door, I asked if I could help. She explained with frustration, the stupid door would not open with the garage door opener and the light kept blinking on and off, so she was trying to open it manually. I’m late for an appointment and now the snow Grrrrrrr.
I remember reading, “To avoid crushing injuries, the door will stop abruptly and reverse. Unfortunately, misalignment of the garage door sensors will cause the door to behave erratically. If your door shows any of these problems, consider examining your garage door sensor for obstruction or misalignment:
- Sudden stops and reversals
- Flashing lights, either on the overhead part or on the sensors themselves
- Opens but does not close”
These garage door sensors work when electricity is transformed into an infrared beam of light. This light is emitted from one side of your garage door from a sending unit that sits 4 inches up from the floor. It sends the beam of light to a receiving unit on the other side of the garage door.
I explained that I have used the Garage Door Doctor and had Daryll the technician come and tune up our two Garage doors.
Daryll from Garage Door Doctor came today and replaced the garage door safety sensors and then checked the safe operation of the door. Now where did I put those snow shovels?

The January 16th Public Board Meeting has been cancelled. The reason for this cancellation is that there are no agenda items beyond the acceptance of past minutes and the adoption of reports from the UBID staff. As such, we have decided to cancel the meeting and save the costs associated. An important part of these meetings is the ability for landowners to ask questions of the Board of Trustees. If there are any questions you would have otherwise asked at this meeting, please direct them to Ian Munro, Interim Chair at email@example.com.

Hmmmmm, grant us the serenity to accept the things we cannot change, the courage to change the things we can, and the wisdom to know the difference.
