Isn't that unusual? I thought that aftershocks came a day or so later than the original quake. This thing has me nervous, and I've been in many major quakes.

Not that unusual, really. A Magnitude 6 quake will generate a goodly number of aftershocks in the first couple of hours, much like is happening here. The most interesting thing here is how many there were of sizable magnitude right after the first two shocks, and the increasing depth of the quakes. It DOES look like it's tapering off, though. Should be a couple more in the 3.5 to 4 range in the next few hours.
Aftershocks are 100% random. You can have 50 in the hour following a quake, or only three a week after the quake hits. Some quakes have hundreds of aftershocks, and others have none at all. It's different for every quake.
If you really want to stress, think about this: it's always possible that this is simply a foreshock to a larger quake. The odds of that will decline substantially over the next few days, but there's no way to know until it hits.
