one of the attributes of an act of god is being unpreventable by humans.
in the event of something like this, having the supplies to just weather the fallout would be best. a years worth of supplies on-hand would be a good start.

That may be, but the set of things that humans can prevent gets larger over time. For example, 100 years ago, an asteroid hitting the earth would be an act of God we could do nothing about, but today it is at least within the realm of possibility that we could observe a large asteroid on a collision course and send in a spacecraft or missile to divert it. https://en.wikipedia.org/wiki/Asteroid_impact_avoidance
As much as I hope I never witness this, watching humanity strap a rocket to an asteroid for this purpose would probably rank #1 on the list of Most Bitchin Things Ever.
