Revelation 8:8-10

Amplified Bible

⁸ The second angel sounded [his trumpet], and something like a great mountain blazing with fire was hurled into the sea; and a third of the sea was turned to blood;^{(A) 9} and a third of the living creatures that were in the sea died, and a third of the ships were destroyed.

¹⁰ The third angel sounded [his trumpet], and a great star fell from heaven, burning like a torch [flashing across the sky], and it fell on a third of the rivers and on the springs of [fresh] waters.
