Are the tribulation trumpets sounding?
Revelation 8:8-11
Then the second angel sounded: And something like a great mountain
burning with fire was thrown into the sea, and a third of the sea became
blood. And a third of the living creatures in the sea died, and a third of the
ships was destroyed.
Then the third angel sounded and a great star fell from heaven burning
like a torch, and it fell on a third of the rivers and on the springs of
water.
The name of the star is Wormwood. A third of the waters became wormwood,
and many men died from the water, because it was made bitter.
