Destructive events in nature are morally neutral in themselves.
A flood is just a wave of water passing over dry land. An earthquake is a shaking of the ground, typically caused by the motion of tectonic plates. Other “natural disasters”—volcanic eruptions, heat waves, cold waves, storms, and so on—fit the same pattern. They are changes in an environment caused by natural, physical forces.
We think of them as destructive disasters because of the impact they have on humans and other life-forms. If a flood, quake, or volcanic eruption occurs on a lifeless planet or moon then there is no harm. Such events are only physical evils when they impact life. Otherwise, they just involve natural forces moving matter around.
Sometimes an event is good for some life forms and bad for others. The cataclysm that killed the dinosaurs made the rise of mammals and man possible. If an earthquake causes a fox’s den to collapse, killing the fox, it allows all the rabbits the fox would have eaten to live.
With infinite wisdom and goodness God freely willed to create a world “in a state of journeying” towards its ultimate perfection. In God’s plan this process of becoming involves the appearance of certain beings and the disappearance of others, the existence of the more perfect alongside the less perfect, both constructive and destructive forces of nature. With physical good there exists also physical evil as long as creation has not reached perfection.
Fires are caused by the abuse of disposable BBQs - do you want God to send a thunderbolt into the factory that produces them ? Really?
We have a drought in much of UK because we haven't used our resources wisely. Instead of being proactive and building reservoirs and mending leaks in pipes, Water Companies have concentrated on giving divvies to their shareholders.
Nothing to do with God. More to do with Man's greed.
Now we are experiencing the results of that folly.
