Thunder?

I was reading a book when I heard a big noise along with the windows shivering. 'Earthquake?' I thought. I ran down the stairs to the room where my parents were sleeping. I asked my mom 'Did you heard that?' She said 'That was thunder, sweetheart. Did u get scared?' I replied, 'Yes'. I turned and walked back to my room. In another few minutes the power failed. It took 45 minutes for power to come back and for me to go to sleep. 
I woke up in the morning and my mom met me with a grin on her face. She said 'Do you know what happened yesterday?' I replied with a confused look 'No'. My mom continued 'There was a bomb blast in Rajendranagar (a place which is located 1- 2 km from my house). See the newspaper.' I read the news for details. So that was a neither a thunder nor an earthquake but a blast!
