Earth Quake maybe.”Why can meteors create sonic booms?The American Meteorological Society explained that meteors travel through the atmosphere at extremely high speeds. Larger space rocks that survive longer in the atmosphere can generate pressure waves strong enough to produce sonic booms, as per reports from CBS News, NBC Boston and The Mirror."Friction with Earth's air causes them to begin vaporizing, leaving a bright streak across our sky. Meteors can zip through the air at 25,000 to 160,000 miles per hour (11 to 72 km per second)," they said on their website. "They can penetrate deeply enough into the atmosphere to produce pressure wavesand, thus, sonic booms."As of Saturday, authorities reported no hazards or damage linked to the event, even as the loud boom remained one of the day's biggest talking points across Massachusetts.FAQsWhat caused the loud boom heard across Massachusetts?Meteorologists believe it was caused by a meteor, or bolide, entering Earth's atmosphere.Was there any reported damage?Authorities said there were no immediate reports of damage or hazards.
