A Memorable Earthquake today

So I was sitting on the couch in our family room this morning 
writing an email to my cousin, 

when suddenly I heard some rattling. 

The front door was shaking 

and then it sounded like a large animal got on our roof 

and was walking across it. At this point the front door stopped 
rattling, and the windows in the family room took over. 

I could hear Den from his office down the hall yelling to me, 
"We're having an earth quake!"

I could tell it was an earthquake and I kept waiting to feel the 

shaking, but I never did. I felt nothing.

So odd, because even small earthquakes will wake me up. 

Then about 5 minutes later both my phone and Den's, 

let out a loud alert. 

Picking it up, this what we saw:

Why was it sent out 5 minutes after the fact?
No one seems to know. 

Actually, I'd rather have the alert after the earthquake,
than before. 

Bad news is not so hard to take when it's already over.
