    Boom! A loud rumble barreled across the Philadelphia region this morning.

    Tweets with the word "shook" skyrocketed moments after a loud thunder clap was heard about 10:20 a.m. Was it an earthquake? No, the loud boom heard was thunder.

    NBC10 chief meteorologist Glenn "Hurricane" Schwartz says it was caused by lightning that amplified due to the cold air.
