Ans: Earthquakes occur on faults - strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
September Weather in Vancouver is mild and comfortable.: Allan Fotheringham once called Vancouver the Canadian city with the best climate and the worst weather. September has the potential to show visitors great Vancouver weather -- mild and clear; however, dull and grey is another possibility. 1  Average September temperature: 14.4ÂºC / 58ÂºF. 2  September average high: 18.3ÂºC / 65ÂºF. 3  September average low: 10ÂºC / 50ÂºF. 4  September is not so rainy in a city famous for its rain.
Re: Best Time To Visit Vancouver Dec. 3, 2006, 2:43 p.m. If you have the luxury of choosing the time you visit Vancouver, it would be nice to follow 1BCTraveler's advice and go in May / June or else in September. That said, if you are forced to visit the area in the busy summer months of July and August, don't despair. Unlike small tourist resort towns that shrink and swell with the seasons, Vancouver is a sufficiently large city that it is able to absorb its summer visitors. At least that's how I feel when I go there.
