The trumpets in Seraph seem to be loosely based on the trumpets in the Bible. Yu, the second trumpet, appeared with a pillar of flame, which agrees with the mountain of flame Wikipedia describes. The fifth trumpet (Mirai) had Abaddon and looked really creepy. Since the seas are poisoned with acid rain or whatever, it looks like the third trumpet probably appeared when the Apocalypse first began. In the Bible, I believe the trumpets are supposed to appear in numerical order, though.
