"And we know that all things work together for good to those who love God, to those who are the called according to His purpose." ~ Romans 8:28 (NKJV)
Why does God allow earthquakes, tornados, hurricanes, tsunamis, typhoons, cyclones, mudslides, and other natural disasters? Tragedies such as Hurricane Katrina in 2005, the 2008 cyclone in Myanmar, the 2010 earthquake in Haiti, and the 2011 earthquake/tsunami near Japan cause many people to question God’s goodness. It is distressing that natural disasters are often termed “acts of God” while no “credit” is given to God for years, decades, or even centuries of peaceful weather. God created the whole universe and the laws of nature (Genesis 1:1). Most natural disasters are a result of these laws at work. Hurricanes, typhoons, and tornados are the results of divergent weather patterns colliding. Earthquakes are the result of the earth’s plate structure shifting. A tsunami is caused by an underwater earthquake.
The Bible proclaims that Jesus Christ holds all of nature together (Colossians 1:16-17). Could God prevent natural disasters? Absolutely! Does God sometimes influence the weather? Yes, as we see in Deuteronomy 11:17 and James 5:17. Numbers 16:30-34 shows us that God sometimes causes natural disasters as a judgment against sin. The book of Revelation describes many events which could definitely be described as natural disasters (Revelation chapters 6, 8, and 16). Is every natural disaster a punishment from God? Absolutely not.
In much the same way that God allows evil people to commit evil acts, God allows the earth to reflect the consequences sin has had on creation. Romans 8:19-21 tells us, “The creation waits in eager expectation for the sons of God to be revealed. For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God.” The fall of humanity into sin had effects on everything, including the world we inhabit. Everything in creation is subject to “frustration” and “decay.” Sin is the ultimate cause of natural disasters just as it is the cause of death, disease, and suffering.
