It was recently reported that an extraordinary seismic event shook Earth on November 11. It was picked up by earthquake sensors that are stationed across the world.
The cause of this disturbance has been unknown for a while, but it seems to be linked somehow to an ongoing seismic swarm that has been rumbling the archipelago of Mayotte in the Indian Ocean for a few months now.
What is still not very clear is what this strange tremors ultimately mean.
“I don’t think I’ve seen anything like it,” seismologist Göran Ekström from Columbia University told National Geographic about the November 11 anomaly.
Anyway, Stephen Hicks, a seismologist at the University of Southampton, tweeted a day after the event on November 12: “Something biggggg, yet strangely slow, sent seismic rumblings around the surface of much of the planet yesterday.”
After that, a discussion that took place on Twitter erupted between various experts who seemed to not quite be able to place their fingers on what happened exactly to trigger all this.
Yep folks, something biggggg, yet strangely slow, sent seismic rumblings around the surface of much of the planet yesterday. The event seems to have happened west of Madagascar. Best analogue so far is a prolonged roof collapse of a volcano magma chamber. Thread👇#twitterscience https://t.co/nb8qsUY8M8

Suggestions were multiple, and they included potential causes such as tectonic earthquakes, landslides, meteorite impact and some of them went so far to guess that the “sea monsters” are to blame.
One plausible theory
Of course, all of these were ruled out, and there was one theory instead that the scientists believed to be the most viable of them all.
Anthony Lomax who is an independent seismology consultant told the MailOnline that the shakes were “almost certainly” triggered by undersea activity to the northeast of Mayotte.
“Inflation/deflation and collapse of volcano calderas, and movement of magma under a volcano can produce a wide variety of seismic signals, including long period and repetitive waves like those observed November 11,” he told the Mail.
More scientists are planning to survey the ocean in order to find out any potential additional data that could help explain the mysterious event.
