I'm missing quite a few recent earthquakes, such as Haiti and such, because I don't know how to place them. Very few of these earthquakes had actual measurements, which is a shame.
In different parts of the world the actual probability (per year) of getting a certain PGV varies. In California, 5-10 cm/s would be 'every day', and thus there would not be any additional damage. In eastern North America, 5-10 cm/s might be only 1% chance per year.
