I’m around 8 miles west of Boston. I was playing on the floor with my daughter and had my ear to the ground- suddenly heard all of the windows shaking, the floor rumbled and an explosion louder than I’ve ever heard before.

Honestly what spooked me the most was seeing nothing on the horizon to help explain it! I am shocked and grateful it didn’t break any windows or cause further damage.

I'm in Watertown on a busy road and was near an open window when it exploded. I thought a truck had slammed into my building and was baffled when I saw everything was fine.
