As pointed to in this hymn: the final Judgement and God making all things new is the cure for earthquakes.
Who then shall live? And face the throne,
And face the Judge severe?
When earth and heaven are fled and gone,
O where shall I appear?
You assume that earthquakes are a negative event that must be cured? They are a process, just like the wind. They are as much creative as destructive. Is it kind of presumptive to think they must be ‘cured’?
Maranatha, Jesus!!!
