Strange seismic waves that were rocked around scientists from around the world

The mysterious wave of seismic waves traveled thousands of miles across the world, excluding sensors across Africa, Canada, New Zealand and Hawaii, seemingly without being felt by one person.

Key points:

  • Seismic waves starting from the coast of Mozambique caused sensors in Kenya, Chile, New Zealand and Canada
  • The tremor lasted more than 20 minutes
  • The earthquake was unnoticed until it was erected by an earthquake enthusiast online

Tremors began just off the coast of Mayotte, a French archipelago in the Indian Ocean, between Madagascar and Africa, and would fly under the radar, if not for the Earthquake enthusiast in New Zealand, who was set on the real geological survey of the United States, time seismograms depicts internet.

They published images from Twitter readings, prompting researchers from around the world to try to locate where these bizarre waves came.

Unlike traditional earthquakes that are causing a blow from various high frequency waves, the observations from the Mayotte tremor have collected consistent low-frequency waves that lasted more than 20 minutes. It was as though the planet was ringing like a bell.

Online theorists suggest secret nuclear tests, marine monsters or meteorites as a cause of tremor, but Goran Ekstrom, a seismologist at Columbia University, told National Geographic that it is probably an explanation.

"I do not think I've seen anything like that [but] this does not mean that, in the end, the cause for them is exotic, "he said.

Professor Ekstrom suggests that the seismic event actually began with an earthquake. He thinks he was secretly because he was a slow quake.

The slow earthquakes are quieter than traditional earthquakes, since they come from a gradual release of stress that can stretch over a considerable period of time.

"The same deformation happens, but it does not happen like a blow," said Professor Exstrom.

Since May of this year, Maya has been subjected to what is known as the "earthquake swarm"; a cluster of hundreds of seismic events over a period of days or weeks, but activity has dropped significantly in recent months.

An analysis of French geological research suggests that strange waves may indicate a mass movement of magma under the earth's crust, such as the collapse of the chamber.

The rhythmic movement, such as spraying the molten rock, or a wave of pressure through rheocene through the body of the magma, has the potential to resonate in a similar way to the readings of Mayotte.

The Democratic Republic of the Congo was the site of a similar event in 2002, where similar slow earthquakes and low-frequency waves were linked to a magma chamber that collapsed under the Niagaraon volcano.
