That question is impossible to answer... sorry :(
Vancouver has so many earthquakes because it is along the ring of fire, a fault line.
Just about everywhere on Earth can have earthquakes. Some locations are more known for it than others, but it turns out that one of the largest earthquakes ever in the United States was in Missouri, a location not particularly noted for being earthquake-prone. Anywhere there's a fault, there can be earthquakes. The recent (November 2011) Oklahoma quakes occurred along the Wilzetta fault.
No. Earthquakes in California, Nevada, and Alaska are primarily the result of normal tectonic acitvity. Some earthquakes in Alaska and northern California are associated with volcanoes, but not supervolcanoes. Earthquakes in Colorado, Missouri, and Oklahoma are related to intraplate stresses and have nothing to do with volcanic activity. Some earthquakes in Oklahoma may be triggered by hydraulic fracturing used to extract oil and natural gas.
Because they are on a default line
Oklahoma is located entirely on the North American Plate well away from any plate boundaries. The earthquakes that have been striking Oklahoma are intraplate earthquakes associated with stresses and faults in the interior of the plate.

There are are a great number of very small earthquakes in Oklahoma. In the past 30 days, there have been 162 earthquakes in the northern Oklahoma/southern Kansas region with an average magnitude of about 2.9 and a maximum magnitude of 4.5. These may be related to hydraulic fracturing to extract oil and natural gas.
Oklahoma has had more then 50 small earthquakes in 2010, most within 50 miles of Oklahoma City, OK.

No. Many earthquakes have no impact. The majority of earthquakes are so minor that they can't even be felt.
No because Madagascar is not in-between two continental plates so they don't have many earthquakes.
Earthquakes (big and small) happen so many times a day, it is impossible to put a number on it.
