"Terror and pit and snare await you, people of the earth. Whoever flees at the sound of terror will fall into a pit; whoever climbs out of the pit will be caught in a snare. The floodgates of the heavens are opened, and the foundations of the earth shake." NIV Translation
Those that have rejected the fact that God is the cause of the events on the earth will search for answers to what is happening and what they can do to stop it. This is similar to what is happening now with the effort of the nations to stop global warming but, at this time, it will be a much more intense effort.
In this search, people will fall for the devil's great deception which is to say that: "If we all just band together, we can do anything."
This is the same spirit that caused mankind to gather at Babel and attempt to build a tower to reach the heavens. At that time, God intervened to cause men to speak in different languages so that they could not work together effectively.
In this case, God is going to strike the earth itself as a demonstration of the fact that He is in control.
Others, will seek the intervention of other so-called gods to stop the events of this final judgment.
"The earth is broken up, the earth is split asunder, the earth is violently shaken. The earth reels like a drunkard, it sways like a hut in the wind; so heavy upon it is the guilt of its rebellion that it falls - never to rise again." NIV translation
The physical earth will see great disasters and people will run to and fro looking for a way to make it all stop but this final judgment will continue. In the past, God has dealt with cities and nations in partial judgments but this will be the complete judgment of God. Those past partial judgments brought about at least a temporary repentance and turning to God but this one will be characterized by the total rebellion of the people that are left on the earth. Instead of accepting the grace of God, they will oppose Him until the very end.
