What happened when the second trumpet blew (Rev 8)?


A burning mountain is cast into the sea, 1/3 of sea becomes blood, 1/3 sea life dies, 1/3 ships destroyed

And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;

And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed. Revelation 8:8-9
