The Holy Bible, Revelation 16:2

2 And the first went, and poured out his vial upon the earth; and there fell a noisome and grievous sore upon the men which had the mark of the beast, and upon them which worshipped his image.

The Holy Bible, Revelation 8:7

7 The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up.

Journal of Discourses, Orson Pratt 16:43

There must be something connected with the sounding of this trump that is miraculous in order that all nations may hear it. Any sound that can be produced by mortal man does not reach, generally speaking, over about thirty miles from where it originates, which is a very small space indeed. But there will be something connected with the sounding of the trump of the first of the seven angels which will manifest a power which we know nothing of. The sound of that trump will be heard by all people, nations, kindreds and tongues in the four quarters of our globe. I do not know that the sound will be so much louder than some we have heard, but it will be carried by some miraculous power so that all people will hear it.
