Business Insider asked astrophysicist Paul Sutter at The Ohio State University and physicist Mark Boslough at Sandia National Laboratories to help think through the scenario of everyone jumping up on one foot into the air at the exact same time. Assuming all 7 billion people were in the same location (e.g. an area the size of New York City), the results would be:
1) a huge sound like an applause. At 200 decibels (the loudest possible sound ever created on Earth), it could shatter ear drums. For context, a jet engine produces 150 decibels of sound at takeoff, and our pain threshold is at 120 decibels.
2) the ground would begin to shake, and if the jump happened near the coast, it could trigger a tsunami with 100-feet-tall waves.
3) depending on location, possibly an earthquake falling in the 4-8 magnitude range. That means it could be anywhere from a light shake to one that could cause some major destruction to bridges, railways, electric lines, and buildings.
