They found that <a href=\"https:\/\/pubs.geoscienceworld.org\/ssa\/srl\/article-abstract\/doi\/10.1785\/0220230385\/636176\/Shake-to-the-Beat-Exploring-the-Seismic-Signals?redirectedFrom=fulltext\" rel=\"noopener\">dancing fans generated vibrations<\/a> in the ground \u2014 <a href=\"https:\/\/www.snexplores.org\/article\/explainer-seismic-waves-come-different-flavors\">seismic waves<\/a> that matched the beat of each song.<\/p>\n<p>The team shared its findings March 13 in <em>Seismological Research Letters<\/em>.<\/p>\n<p>\u201cIt\u2019s really fun to be able to use seismic tools to understand things like music and concerts and events that bring people together,\u201d says Eva Golos. A <a href=\"https:\/\/www.snexplores.org\/article\/scientists-say-seismology-definition-pronunciation\">seismologist<\/a>, she studies earthquakes but was not involved in the new research. Golos works at the University of Wisconsin\u2013Madison.<\/p>\n<aside class=\"sn-conversion rich-text alignright\"\/>\n<h4 class=\"wp-block-heading\">Stadium vibrations<\/h4>\n<p>This isn\u2019t the first time seismologists have measured vibrations from a stadium. In 2011, Seattle Seahawks fans <a href=\"https:\/\/www.snexplores.org\/article\/ground-thumping-cheers-help-scientists\">shook their home stadium<\/a> with cheers after a stunning touchdown. And last July, <a href=\"https:\/\/rock.geosociety.org\/net\/gsatoday\/science\/G589A\/GSATG589A.pdf\" rel=\"noopener\">Swifties rattled the ground<\/a> at a Seattle concert.<\/p>\n<p>The shaking from those events differs from an earthquake. Earthquakes usually last only a few seconds. A \u201cconcert tremor,\u201d in contrast, can last several minutes.<\/p>\n<p>The ground also moves in different ways during quakes and concerts. Earthquakes happen when huge slabs of Earth\u2019s crust, called <a href=\"https:\/\/www.snexplores.org\/article\/scientists-say-tectonic-plate-definition-pronunciation\">tectonic plates<\/a>, shift around. Those motions permanently change the ground. The shaking caused by crowds doesn\u2019t usually deform the Earth.<\/p>\n<p>Concert tremor \u201cis more like splashing on a puddle of water,\u201d explains Gabrielle Tepp. She\u2019s a seismologist at the California Institute of Technology in Pasadena. \u201cYou see the ripples coming out, but then once you\u2019re done splashing, it just goes back to normal.\u201d<\/p>\n<p>Seismologists use similar instruments to detect earthquakes and concert tremors. In the new study, Tepp\u2019s team set up motion sensors in and around SoFi Stadium in Inglewood, Calif. They did this right before Swift\u2019s first Eras Tour performance there. Those instruments measured shaking from the stadium during Swift\u2019s concert on August 5, 2023. Some 70,000 people attended that show.<\/p>\n<p>For many of the songs performed that night, the <a href=\"https:\/\/www.snexplores.org\/article\/scientists-say-frequency\" data-type=\"post\" data-id=\"5203\">frequency<\/a> of the vibrations lined up with the beat of the song. The researchers could identify almost every song that Swift performed using the frequencies and durations of the vibrations.<\/p>\n<section class=\"newsletter-signup__wrapper___lZ0W1 wp-block-house-ads wp-block-newsletter-signup\">\n<picture><source srcset=\"https:\/\/www.snexplores.org\/wp-content\/themes\/sciencenews-sns-child\/client\/src\/images\/cta-module@1x.png 1x,&#10;&#9;&#9;&#9;&#9;https:\/\/www.snexplores.org\/wp-content\/themes\/sciencenews-sns-child\/client\/src\/images\/cta-module@2x.png 2x\" media=\"(min-width: 768px)\"><source srcset=\"https:\/\/www.snexplores.org\/wp-content\/themes\/sciencenews-sns-child\/client\/src\/images\/cta-module-sm@1x.png 1x,&#10;&#9;&#9;&#9;&#9;https:\/\/www.snexplores.org\/wp-content\/themes\/sciencenews-sns-child\/client\/src\/images\/cta-module-sm@2x.png 2x\"><\/source><\/source><\/picture>\n<div class=\"newsletter-signup__container___srNOL\" data-component=\"newsletter-signup\">\n<h3 class=\"newsletter-signup__heading___0EHmb\">\n\t\t\tEducators and Parents, Sign Up for The Cheat Sheet\t\t<\/h3>\n<div class=\"newsletter-signup__message___pemaq\">\n<p>Weekly updates to help you use <em>Science News Explores<\/em> in the learning environment<\/p>\n<\/p><\/div>\n<p class=\"newsletter-signup__thankyou___K6GGN\">Thank you for signing up!<\/p>\n<p class=\"newsletter-signup__error___hCsJI\">There was a problem signing you up.<\/p>\n<\/p><\/div>\n<\/section>\n<p>The stadium shook most during Swift\u2019s performance of \u201cShake It Off.\u201d During that song, the stands released about as much energy as a magnitude 0.85 earthquake. That\u2019s not quite strong enough to be felt by humans, but it releases as much energy as <a href=\"https:\/\/www.mtu.edu\/geo\/community\/seismology\/learn\/earthquake-measure\/\" rel=\"noopener\">blowing up a few ounces of TNT<\/a>.<\/p>\n<p>That energy was released over the full length of the song. An earthquake (or a TNT explosion) usually releases all of its energy in a few seconds.<\/p>\n<p>The difference between an earthquake and a concert tremor is like \u201cthe difference between a firework explosion and a jet engine roaring,\u201d says Tepp. \u201cThey might release the same amount of energy. But the explosion is happening very quickly. It\u2019s all at once. Whereas with a jet engine, you\u2019re releasing [energy] over a longer amount of time. So it\u2019s not as loud at its peak, but it goes on for much longer.\u201d<\/p>\n<div class=\"wp-block-group cheat-sheet-cta is-layout-flow\">\n<div class=\"wp-block-group__inner-container\">\n<h2 class=\"wp-block-heading has-text-align-center\">Do you have a science question?

Was it jumping fans, the sound system or the instruments?<\/p>\n<p>To find out, the team set up a portable speaker next to a motion sensor in their lab and turned the speaker volume all the way up. Then Tepp plugged in her bass guitar and played a simple beat over the speakers. They also blasted Swift\u2019s \u201cLove Story\u201d at the speakers\u2019 highest volume. Tepp even jumped around near the sensor while grooving to the last chorus.<\/p>\n<p>The sensor picked up vibrations that matched those from the concert only when Tepp was jumping around. That suggests that the vibrations measured on August 5 came from fans jumping and dancing, too.<\/p>\n<p>The findings tell scientists about more than just concert tremor. Understanding how a stadium shakes in response to a large crowd could help make buildings safer, says Golos. \u201cWe can also better understand human behavior\u201d using such seismic data, she says. \u201cI think there\u2019s a lot of interesting information hidden in there.\u201d<\/p>\n<aside class=\"sn-conversion rich-text\"\/><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.snexplores.org\/article\/taylor-swift-fans-shake-seismic-waves\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Taylor Swift fans really know how to \u201cShake It Off\u201d \u2014 and shake the ground.
