When something like this hits, I usually expect to hear the Qs: "Where is God in this tragedy?" or "How could a God of love allow this?"
Very important Qs... and ones we should all ask and attempt to answer.
"Maybe God is putting the brakes on..."
'sending us a warning'
'giving us a wake up call'
'shaking us out of complacency'
'calling us to action'
Or,
"What is a God of love trying to say to us/show us?"
Or,
"If we as humans have messed up this world, what kind of world would a God of love have us build?"
"How would a God of love have us treat one another?"
"How would a God of love have us treat the planet?"
(Hint: The answers can be found in Creation / Christ / His Kingdom / New Creation!)
Instead we need to spend our time casting a vision for a different world. A better Kingdom.
1) Initially: How did we mess up the world so badly / become so vulnerable?
2) In Isolation: How do we cope now we can't rely on all that we knew? And what is it that truly matters in life?
4) As we start to emerge: What new world should we seek to build?
