J.T.,
Actually I don't believe that God or Satan is responsible for earthquakes. Earthquakes are just a part of our existence. I have long stopped playing the blame game of either God or Satan. If there is a God or a Satan earthquakes do happen. And if there is no God or no Satan, they still occur. Earthquakes don't prove or disprove either. What is the purpose of raising such a question if not to try to disprove a god? But if there is a god and he allows earthquakes to occur, than how could your disapproval or unbelief effect him? After all, he is god and you're not, so how could you ask him to render an account to you? And if there is no god as so many maintain, you are still stuck with nearly 30,000 people who died in an earthquake. AND NOT NATURE, NOT THE UNIVERSE OR ANYONE ELSE PREVENTED IT! Nor will anyone stop your death or mine when it comes. But I know it is inevitable. So what does it matter if I die in an earthquake, or natural disaster, or by disease or an accident or murder? I know I'm not here to stay; there is no permanence here and I'm no better or different than the people of Bam or the millions who have preceded us in death. Death is the great equalizer. But I expect the question of why to remain. However, are we asking the wrong question? Should it not be why not instead?
Also, could man at least be partially responsible for building where he does? Since we know that hurricanes, earthquakes, floods, etc. do occur, why do we still concentrate on building along beaches, fault lines, and in flood prone zones? Everyone talks about the "big one" due for California, but no one will leave. And when it does occur, everyone will ask why a god didn't stop it. True, we can't foresee every natural disaster, but even in those areas that we know are risky, we still take the chance, come what may. And as far as chances go, sometimes we lose.
