I have a really old fridge in my apartment. Sometimes when I work with headphones on, I think someone is knocking on the door. Taking off my headphones I realize it was just the fridge that stopped and made the floor shake.
Earlier today the house was shaking once; a bit like someone drove a car into the wall. Except that would probably have made it fall over completely. It seems like it was a little earthquake 8 miles away.
Just a few minutes ago it happened again, but it's not on the page yet. Oh, now it is.
When you are from a country with almost no earthquakes, it takes some years to get used to the occasional realization that even when you live in the middle of the comfortable "civilization", the earth is so powerful and we are so small.
