Earthquake lyrics

This song is describing a relationship gone wrong. The relationship seems to be ruined by the singer, as it is hinted to in the line " I made this mess, I built this fire ". The "Earthquake" in this song is probably the break up. The line " Apparently the kind that would bury us alive " describes how badly the relationship was ruined, in this case it was ruined beyone the point of repair. The singer is asking for forgiveness as he wants the woman back. Now when the singer speaks of the ocean, as in " I sink now to the ocean floor...I lie here on the ocean floor " He is talking about the choice of death or suicide he wishes to take for destroying the relationship.
