The mysterious waves of seismic waves travel thousands of kilometers around the world, shutting down sensors across Africa, Canada, New Zealand, and Hawaii, seemingly without a single person.
- Seismic waves that start from the coast of Mozambique have triggered sensors in Kenya, Chile, New Zealand and Canada
- The duration lasted more than 20 minutes
- The earthquake remained unnoticed until the earthquake wizard
Horrors began right off the banks of Mayotte, the French Indian Ocean archipelago between Madagascar and Africa, flying under radar, if they were not a New Zealand earthquake enthusiast who was attuned to the realistic work of the US Geological Survey, the time seismogram is online.
Reader readings have gone on Twitter and have led researchers from around the world to try to find out where these bizarre waves come from.
Unlike the traditional earthquakes that cause vibrations of different high frequency waves, Mayotte's tremor reads consistent low-frequency waves that last more than 20 minutes. It was as if the planet was ringing like a bell.
Online theorists suggest hidden nuclear tests, sea monsters or meteorites as the cause of tremor, but Goran Ekstrom, a seismologist at Columbia University, told National Geographic that the explanation was likely.
"I do not think I've seen anything like that [but] it does not mean that eventually their cause is exotic, "he said.
Professor Ekstrom suggests that a seismic event really started with an earthquake. He thinks it went secretly because it was a slow earthquake.
Slow earthquakes are quieter than traditional earthquakes because they come from a gradual release of stress that can prolong for a considerable time.
"The same deformation happens, but it does not happen like poisoning," said Professor Ekstrom.
Since May of this year, Mayotte has been subjected to what is known as the "earthquake swarm"; a group of hundreds of seismic events for several days or weeks, but activity has decreased significantly in recent months.

Analysis according to the French Geological Survey suggests that strange waves can indicate the mass movement of the magma beneath the earth's crust, such as the collapse of the chamber.
Rhythmic motion, like the melting of the molten rock or the pressure wave that is hidden through the magmatic body, has the potential to resonate like the Mayotte readings.
The Democratic Republic of Congo was a similar event in 2002 when similar slow earthquakes and low-frequency waves were associated with a magmatic chamber that collapsed under the volcano Nyiragongo.
