The only time I've felt the earth move was the morning when bruncefield went pop.
One of my cousins lives literally next door to that place.
When the explosion ( which woke me up in Epsom, and I'm deaf, though I didn't know
why I had woken up at that time until I saw the news later ) happened he and his wife were fast asleep.
When it hit the news, my aunt rang them up and the conversation ( honest! ) went something like this:
*ring ring*
"Hello?"
"It's your mum here, are you all right?"
"Yes, we are. Why do you ask?"
"Look out of your window!"
