The first four trumpets = The earth became corrupt in Genesis 6:11, destabilizing the planet.
The fifth and sixth trumpets = The earth was filled with violence in Genesis 6:11.
Between the sixth trumpet and the seventh trumpet is Genesis 6:13-21 & Genesis 7:1-4 wherein God (Revelation 10:1) revealed Himself to Noah (Revelation 10:7).
The seventh trumpet = The earth was destroyed by the Flood (Genesis 7:11-12, 17-23), then Noah and his family entered the new world (Genesis 8:18-19).
