Shaken Earth & Fallen Marine: Idea Starting to Germinate!

I'm starting to understand that my book would rather be a collection of "independent but interrelated" stories. My estimation is that the following stories would be relevant:

(1) When the Earth Shook
    My personal experience of the earthquake and how we as family coped with it. It'll be a first-person narrative.
In this story, I'll not only report what happened when the earthquake hit, I will also share my philosophical, psychological and spiritual reflections on the wake of the quake. As an individual, as a society, and as a nation.

(2) Fallen Marine
   The story of US marine helicopter tragedy. I'll add the spices of conspiracy theories surrounding the crash.

(3) When the Everest crumbled
   The account of the death of 22 people at the Everest base camp when the earthquake triggered a massive avalanche

(4) The Last Trekking of so Many
    The account of devastation in Langtang Valley

(5) But God didn't save them!
     The account of several churches collapsing in the earthquake that killed 500 Christians in Kathmandu alone.

(6) The Death Tower
    The killing of 180 people in the country's landmark tower called Dharahara.

(7) Survival Saga
    Accounts of some of the miraculous survivals and rescues.
