The screams caused an earthquake of American football fans

American football fans screaming so loudly that seismic activity skyrocketed, equivalent to a mild earthquake.

When the Seahawks rugby team scored decisive points in the final seconds of a match on Seattle, Washington, USA stadium on the afternoon of October 29, crowds of fans cheered loudly to the geodesic. seizures at the University of Washington that way a building has recorded shocks equivalent to a mild earthquake, according to Science Alert.

Fans of the Seahawks of America are famous for their deafening screams. Seattle Stadium twice holds the Guinness world record for the most noisy cheering crowd. In 2013, the noise at the stadium reached 136.6 decibels and in 2017 it was 137.6 decibels, while a loud rock concert usually only reached about 120 decibels.

Scientists use seismographs to capture seismic waves, vibrations from earthquakes spreading through the Earth's crust. The results obtained measure the intensity of the earthquake. For example, a mild earthquake of less than two intensity and people hardly feel.

Professor John Vidale of the University of Washington confirmed that the fans shouted so loudly that it seemed like a slight earthquake had occurred."It may be an energy from an earthquake of magnitude. Although vibration is small, it lasts for quite a long time," Professor Vidale said.

This is not the first time humans have caused seismic activity. Mining, hydraulic engineering, groundwater extraction, dams and power plants can all lead to seismic activity at a certain level. The same event happened in 2013, when Seahawk team player scored from a ball, the fans also caused the same vibration.
