Mats Hummels said Germany's tactical approach was wrong after the World Cup holders lost the opening game of their title defence 1-0 to Mexico.
On Sunday, the institute tweeted seismographic readings highlighting the activity at the time when Mexicans celebrated what would be the decisive goal scored by striker Hirving Lozano.
Munich-based newspaper Sueddeutsche Zeitung agreed with "There are reasons to worry" over a picture of the dejected German team, who need to beat Sweden and South Korea to be sure of going through.
Here's the reaction from Mexico City...
Should Germany turn things around and go on a winning run to retain the trophy, they would become the first team since the Brazil side of 1962 to do so.
"We're under pressure now, without question, we have to get six points from the two games, if possible".
"Mexico deserved the win", Hummels conceded. I thought we would not have a chance.
"You could hear already yesterday that players were self-critical", he said.
"He told us to keep playing like we were playing".
"Holy crap I love my country".
Marquez played for Barcelona between 2003 and 2010 and plans to retire after the World Cup.
Following the victory, social media was abuzz and the tournament finally come to life with Mexico defying the odds and beating Germany in their match opener, something unseen since 1982. Possibly by massive jumps during the goal of the selection of #México in the World Cup.
Traditionally, worldwide football has been dominated by teams from Europe and Latin America and there exists a healthy rivalry between the two regions.
