The Seven Trumpets
When the first trumpet is sounded in Revelation 8:7 hail, fire and blood fall upon the Earth, and a third of its surface, along with a third of its trees and all of its grass, is consumed in flame.

Upon the sounding of the second, a great, flaming mountain falls into the sea.  A third of the oceans turn to blood, a third of the sea creatures are killed, and a third of the ships are destroyed. With the third, the star Wormwood falls upon a third of the rivers and springs, poisoning them and the many men who drink from them.
