Earth Quake in Islamabad

I had just gone to sleep with an aching stomach and was not yet fully slept when a power jolt shaked all the underconstruction building on 1st floor of which we have got a room. All the previous day I was out in Islamabad and Pindi and had came after evening was well in. Here the night was not good as i was feeling immense pain in my stomach which is still quite there now. After the quake subsided i was unble to go to sleep and remained vigilant for any aftershocks through out the night. The quake was unusully powerful and I felt really worried. I felt it was more powerful than the 2005 one when I was in Peshawar. However no loss of life or any other damage is reported.
