Natural disasters are chastisements from God meant to get people to turn to Him with a contrite heart. God bless you.
I agree with this. We can find all over in Sacred Scripture that God is at work in the forces of nature whether for good or ill. The world is God’s creation and He is the first cause of everything that happens and He watches over his creation by His providence as the CCC says:
303 The witness of Scripture is unanimous that the solicitude of divine providence is concrete and immediate; God cares for all, from the least things to the great events of the world and its history. the sacred books powerfully affirm God’s absolute sovereignty over the course of events: “Our God is in the heavens; he does whatever he pleases.” and so it is with Christ, “who opens and no one shall shut, who shuts and no one opens”. As the book of Proverbs states: “Many are the plans in the mind of a man, but it is the purpose of the LORD that will be established.”
304 And so we see the Holy Spirit, the principal author of Sacred Scripture, often attributing actions to God without mentioning any secondary causes. This is not a “primitive mode of speech”, but a profound way of recalling God’s primacy and absolute Lordship over history and the world,and so of educating his people to trust in him. the prayer of the Psalms is the great school of this trust.
308 The truth that God is at work in all the actions of his creatures is inseparable from faith in God the Creator. God is the first cause who operates in and through secondary causes: “For God is at work in you, both to will and to work for his good pleasure.”
Natural disasters are the result of original sin and the sins of human beings since the fall of Adam and Eve. As Ready has said, I believe they are meant for us human beings to turn to God. Jesus said "Or those eighteen people who were killed when the tower at Siloam fell on them*—do you think they were more guilty than everyone else who lived in Jerusalem? By no means! But I tell you, if you do not repent, you will all perish as they did!” (Luke 13: 4-5).
Nothing happens in the world but what God wills to happen or wills to permit to happen (St Augustine) and we can be sure that what God wills is never without a good reason.
Natural disasters are not the principle cause of the death of human beings but sin as St Paul says “Therefore, just as through one person sin entered the world, and through sin, death, and thus death came to all, inasmuch as all sinned” (Romans 5:12). Natural disasters are
instruments of God. If Adam and Eve had not sinned then I believe God would have prevented natural phenomenon from harming them. Even now, if all human beings turned to God, I think God would prevent natural phenomenon from harming human beings.
