How do volcanoes remind

us that god still cares for

This world

I'm not really religious but I will take a shot looking from your perspective.

He shows that he is still acting around us by showing how powerful he is and that to remind us that he still does things on this earth and still acts around this earth.

There is no proof of a "god", but if there is one, why would the world have tornados, hurricanes, floods, poverty, wars, and etc.?
