Your premise that God is all-powerful and causes only good is also my understanding. The Biblical prophet Elijah also realized God was not in wind, earthquakes, or fire (I Kings, chap. 19). I believe that people can either look at disasters as God-ordained or try to see evidences of God's protection from such disasters.
For example, when the powerful Northridge, California, earthquake of 1994 literally tossed me out of bed, I could have been impressed by its magnitude. But as a former architect, I knew that such disasters often lead to enhanced building codes that enable structures to better withstand future threats. In one building I designed, we made use of maps based on years of flood data that helped to protect the building, ensuring everyone's safety during major flooding.
