Revelation 8:9 is the second trumpet where a third of sea creatures die, continuing the series of 'third' judgments that includes the darkening here.

Revelation 8:7 is the first trumpet with hail and fire burning a third of the earth, sharing the same 'third' pattern as the fourth trumpet here.

Revelation 9:15 releases four angels to kill a third of mankind, repeating the 'third' fraction found in the fourth trumpet's judgment.

Revelation 9:2 describes smoke from the abyss darkening the sun, directly echoing the fourth trumpet's darkening motif.

In Rev 16:8, the sun scorches people with fire—a different sun judgment, showing a sequence of plagues affecting the sun.
