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.
In addition, Vancouver is one of the driest cities in Canada during the summer season, but the rest of the year the high pressure that locks in during the summer moves out and is replaced by the usual low pressure systems (rainy weather) by fall through to mid spring.
