Everything has a cause and God cares, He cares for each and everyone of us. The problem is that we imagine he works in certain ways and when he doesn't we are disappointed and blame God rather than realising it may be our idea of God that is wrong and not God himself.
There are two causes of tragedy one is man made, road accidents, war, and drugs, to give only three examples. The second cause is natural, two of which would be volcanic eruption and earthquakes that divide the land from the sea and form new land mass. Without these things happening we wouldn't have the world we have today. Death, decay, and regrowth is what atheists call evolution but some Christians might think of it as creation.
Either way that is the way the world is made and to try to say the natural world should be different is not a possibility. Rain falls and causes land-slides and flooding, snow falls and there are avalanches. To say God should change the natural order of things to avoid natural disaster is frankly impossible and for someone who does not believe in God is simply amazing.
Remember we have a responsibility to ourselves and even the simple act of coming to Jesus for forgiveness is down to us but thankfully we are saved by his loving kindness and grace for he said "Come unto me all ye that labour and I will give you rest."
