Experts have challenged the news that Mexican football fans caused an artificial earthquake in celebrating their country's 1-0 FIFA World Cup win against Germany.
Social media was abuzz with claims that jubilant celebrations when the country scored its one goal caused a spike in seismic activity.
The claims seemed to have originated from a tweet by seismic monitoring network Simmsa which said an artificial earthquake could have been generated at that time by "massive jumps".
But Mexico's National Seismological Service (SSN) issued a statement on Wednesday saying this was highly unlikely.
It said there were two small earthquakes registered at 10:24am and 12:01pm while the game was played, but the goal happened about 11:35am.
These two small earthquakes were also actually located north of Mexico City.
"These earthquakes are due to the seismic activity typical of the Basin of Mexico," it said.
The Mexican team, known as El Tri, or "the Tri" because its uniform carries the three colours of the Mexican flag, has not progressed past the World Cup last 16 in 28 years.
It was the first time since 1982 Germany failed to win their opening game at a World Cup.
