Messi’s seismic sorcery literally makes the ground move

-

VIENNA — It’s a scientific fact that when living soccer legends Neymar or Lionel Messi score a goal, the Earth moves and the ground shakes. Don’t believe it?

Ask Jordi Diaz, a researcher at the Institute of Earth Sciences Jaume Almera in Barcelona. He’s got the hard proof.

“We put a seismomete­r inside a building in Barcelona,” he explained at a geoscience­s conference in Vienna, where he presented his findings.

“This allowed us to identify signature vibrations produced by different activities, including traffic or subway trains.” Or soccer matches. By design or not, the instrument — which measures everything from tremors to full-on quakes — was about half a kilometer from Nou Camp stadium, home to the city’s fabled soccer team.

“We get informatio­n every time there is a goal,” he said at a media conference.

“Well, every time Barcelona makes a goal. People jump and the stadium shakes.”

Exhibit A: A graphic display of the Champions League knockout tie last month versus English team Chelsea that saw Messi score twice in a 3-0 Barca victory.

The inky spike provoked by his first goal, after three minutes of play, looked like the liedetecto­r answer when the murderer swears he didn’t do it.

The second goal — an hour later when the game was largely won — didn’t provoke the same level of vertical enthusiasm.

The historic, come-from-behind, 6-1 victory against Paris Saint Germain last year, which put Barcelona into the Champions League quarterfin­als, looked like a crescendo of earthquake­s ending in the Big One.

But a soccer game is not — seismicall­y speaking — the same as a concert.

“Sometimes we have beautiful seismic recordings from rock concerts, particular­ly Bruce Springstee­n or U2,” Diaz said.

“You see what we call ‘harmonic structures’, energy localized in a precise amplitudes.

“This is because people are not jumping, they are dancing.”

He recalled a Springstee­n concert from last year in which “every single song had a particular pattern”.

Marathon races, wind bursts, ocean waves — each has its own seismic signature, he said.

Why bother?

“At first, it was mainly for outreach, to show people how a seismomete­r works,” he said.

But then other — perhaps more practical applicatio­ns — came into focus.

The technique, for example, could be an easy, inexpensiv­e way to conduct a long-term survey of traffic or subway activity.

And it could be handy in providing evidence that transport workers have gone on strike, he added.
