There are brachot said on phenomena and events. According to the instructions in the Artscroll, one says the lightning/thunder and rainbow blessings no more than once each day unless clouds dissipated and then returned. In that case, they can be said more often. The remaining blessings are said no more than once in every 30 days.
If the remaining blessings (earthquake/comet, the ocean, beautiful things, strange looking things, a Torah scholar, a secular scholar and a gentile king) are made on the idea (a king, like the notion of a thunderclap thunder storm) then I can understand not saying it again, but if the blessing is on the specific iteration (as it appears by the exception regarding a new thunderstorm) then would the same exception be made for the other blessings?
If I see both the Atlantic and Pacific oceans during the same day, or see two different strange looking animals an hour apart, is that like two separate thunder events or does the 30 day rule hold true.
