Why did my adapter go out, and how do I prevent that?

On Sunday morning we had a power outage here. My Mac's power adapter seems to have gone bad as a result, but none of my other computer parts did. What's the deal?

There was a power outage. Shortly before the outage, we heard what sounded like three gunshots about a quarter mile from here -- two pops and a slightly louder boom (if that info is useful).
My Mac Mini wouldn't start after the power came back on. I reset the PMU and it worked again. But when I turned it on, the white light didn't come on. The fan was REALLY loud, the entire time I had the computer on.
Software-wise, everything looked OK, but I read a forum post that indicated the adapter might be underpowered and decided to turn off the computer and order a new adapter.
New adapter arrived today. Mac is back in perfect shape.
Now, I have another computer plugged into this outlet, in fact 3 surge protectors total, using about two of them only, though. Why would the Mac Mini's adapter be the only thing affected?
And was there a power surge that caused this? I live in Northern California, and I had something similar happen before, albeit across town. When I lived in Seattle, I never had these kinds of problems when the power went out.
I live in a new (last 2 years) house.
If there was a surge, why wouldn't my (new) surge protector protect things? I'm just trying to understand why and what I can do in the future so I don't have to keep losing parts to power problems.
