I live in Hamburg. A couple of weeks ago I had my day screwed over because a bomb was dug up in the city and public transportation went haywire for a day. Last December, Augsburg evacuated 54,000 because of another WW2 era bomb they dug up. When I said this to a local, they responded, "Ja. That happens all the time." I stressed that it was the largest evacuation since the War, and they shrugged, "Meh."
I've only lived in Germany for six months and this has happened twice. I lived in Korea for two years and this never happened. Even though (a truthism?) "more bombs were dropped on Korea than on the entire Pacific theater."
I have my own conspiracy theories about infrastructure in Korea, but that's beside the point. What gives? Were the types of bombs dropped on Korea different from the kind dropped on Germany? Did Korea manage to clean up their battlefields more thoroughly (and with less time) than Germany (and despite their comparative instability)? Were US/UN bombs really THAT concentrated on the north that the south wasn't nearly as affected?

Yes.
The US had an entire fleet of B-29's and razed all of North Korea. The North, China, and (secretly) the Soviets had some MiG's but they were confined to an area north of Pyongyang. Once the lines had stabilized by mid 1951, the US Air Force had a turkey shoot for two years, bombing cities, villages, fields, factories, and eventually (and controversially), dams and other civilian infrastructure. North Korea had no capability to hit the south with planes at that point.
That said, bombs ARE found in Korea. The procedure is to call the army and they send out the bomb squad to remove them. I am personally aware of two incidents within the past ten years, but one of those was NOT an airplane bomb but an artillery shell. It was found on the campus of a university in Daegu. I'll see if I can find the report of it.
