HONOLULU (AP) — A Hawaii tsunami warning that spurred coastal evacuations statewide was downgraded to a tsunami advisory early Sunday, ending the threat of serious damage less than three hours after the first waves hit the islands.

This earthquake is likely associated with relative motion across the Queen Charlotte fault system offshore of British Columbia, Canada. Studies of tectonics in this region suggest plate motions are taken up by strike slip faulting parallel to the plate boundary, accompanied by lesser amounts of thrust motion to accommodate the oblique nature of the plate motion vector between the two plates with respect to the orientation of the main plate boundary fault structure. This oblique component of plate motion may involve either underthrusting of the western edge of the Pacific Plate beneath North America, or be taken up on crustal faults within the North America plate. The October 28th earthquake is consistent with either scenario.
This region of the Pacific:North America plate boundary has hosted 7 earthquakes of magnitude 6 or greater over the past 40 years – the largest of which was a M 6.6 earthquake in 2009, 80 km to the south east of the 2012 earthquake. In 1949, a M 8.1 earthquake occurred closer to the Pacific:North America plate boundary, likely as a result of strike-slip faulting, approximately 100 km northwest of the October 28th earthquake, near the northern extent of Haida Gwaii region (formerly Queen Charlotte Islands).

Get your car ready for winter driving conditions by:
- Make sure your tires are in good shape and are rated for the conditions. Check your spare tire too.
- Carry chains where required by law. Learn how to install the chains properly before you need them.
- Have all belts, hoses, brakes, and steering components checked by a licensed mechanic.
- Change your wind-shield wipers.
- Top up all fluids to the proper levels. Carry extra wind-shield fluid.
- Check your safety kit for blankets, water, food, extra medication, first aid supplies, and road markers
Keep care of yourself by:
- Not driving when sleepy, or under the influence.
- Not driving in poor conditions when it is not necessary.
- Planning your trip carefully and sharing your route with friends and family.
- NOT TEXTING or TALKING on a cell phone. Pull over safely when using a phone.

The Canadian Red Cross recently learned that 64 percent of us use social media. So, what are the expectations in an emergency…. go to http://redcrosstalks.wordpress.com and get all the information. Some of the results are definitely cause for concern.
“Comox is the third busiest marine traffic centre across Canada handling an average of 900 marine incidents and emergencies per year (behind only Victoria and Halifax). In total, the five west coast centres handle 60% of all marine incidents and traffic movements in Canada.”

Public Advisory: Increased flows on Nanaimo River
NANAIMO – The public should use extra caution when using the Nanaimo River for recreation next week, due to increased water flows.
Starting on Monday, Oct. 1, 2012, Harmac Pacific and the City of Nanaimo will be releasing more water from two reservoirs to improve fish access through the rapids into the Nanaimo Lakes spawning areas.
Anyone using the river – especially boaters and swimmers – should be aware of the increased water flows and use extra caution. Increased flows can combine with storms to create strong currents and undertows. The higher water levels are also expected to raise water levels at the Highway 19 bridge later in the week by about 0.3 metres (one foot). The higher water levels may last for two to three days.
Harmac Pacific will be releasing water from its Fourth Lake reservoir, increasing flows from 2.83 to 7.07 cubic metres per second (100 to 250 cubic feet per second) starting Monday, Oct. 1. The City of Nanaimo will be releasing water from its Jump Lake reservoir, increasing flows from 1.00 to approximately 6.80 cubic metres per second (35 to 240 cubic feet per second) starting Wednesday, Oct. 3.
Water release dates vary each year, depending on the number of fish entering the river and river flows resulting from rain. Present river flows are slightly below average for this time of year. Nanaimo Hatchery staff are constantly monitoring fish movements in the river by conducting fish-count swims.
These fall pulse releases of water have been taking place for more than 20 years and are the result of an agreement between several agencies, including Fisheries and Oceans Canada, the British Columbia Ministry of Forests, Lands and Natural Resource Operations, the City of Nanaimo and the Snuneymuxw First Nation, as well as Nanaimo Forest Products, which operates Harmac Pacific.
