God did not will the events you mentioned terced ojos, god allowed them to happen because mankind has not yet come to the end of themselves. Like you and others they do not agree with a Creator God and so god leaves them alone, for the most part, but repent and be saved and he will never leave you alone. The christians who die in these occurances are finished their earthly trial and will obtain an inheritance with God whom they worshiped. Never worry or be sad about a christian dying, for us it is soon to be with the Lord Jesus.
(onto the question)
nothing will deter the wrath of God. His tribulation period is set in stone. To pray to deter the natural disasters is to pray a miss, to pray that people be saved during those disasters is to pray a hit.
For in every disaster, life of struggle, bad scenario there is always a number of unsaved turning to the God of heaven and earth and of the bible.
Don't forget the biggest earthquake of all time is to happen at the Lords returning.. where geography changes so much that mt Everest is no longer the highest mountain but Zion becomes the highest mountain. We cannot pray this away. Come Lord jesus.
