Another earthquake this morning. I woke up at 4:55 - for no reason at all. Then I heard something like a loud rumble and a moment later, the house shook hard. I felt it much stronger than the last one -- or maybe, my memory has edited the sickening feeling of a house moving around you. It was only a 5.1, compared to 5.6 last time. It was short, over in a few seconds. No (palpable) aftershocks so far, although I lay awake until the kids woke up at 6:30. It wasn't the big one Romania is waiting for. Sigh.
