Ripple mystery of & # 39; seismic waves passed by thousands of & # 39; kilometers around the world, attracting sensors across Africa, Canada, New Zealand and Ħawajja, without apparently felt by one person.

Key points:

  • The seismic waves began off the coast of Mozambique led sensors in Kenya, Chile, New Zealand and Canada
  • The shaking lasted more than 20 minutes
  • The quake went unnoticed until it was purchased by the earthquake enthusiast online

The tremors started & # 39; the offshore of & # 39; Mayotte, French archipelago in the Indian Ocean between Madagascar and Africa, and have been flying under the radar if not for entużjatur of & # 39; earthquake in New Zealand was adjusted in The seismograms time appears on the internet.

They asked Twitter to image reading, and led to researchers around the world to try to infer which came these strange waves.

B & # 39; difference from traditional earthquakes, producing shock & # 39; & # 39 different frequencies; frequency, reading from the rigors of & # 39; Mayotte picked consistent waves & # 39; low frequency that lasted more than 20 minutes. It was as if the plant sits like a bell.

Theorists online suggest covert nuclear tests, sea monsters, or meteorite as the cause of the tremors, but Goran Ekström, seismologists at the University & # 39; Columbia, told National Geographic that the explanation x & # 39; likely was directed.

"I do not think I have seen anything like this [but] it does mean that, in the end, their case is exotic, "he said.

The Ekström Professor suggests that the seismic event actually began with the earthquake. He thinks that went undetected because it was slow earthquake.

Slow earthquakes are quieter than traditional quakes due to a slow release & # 39; stress can & # 39; extend over a significant period of & # 39; time.

"The same deformation occurs, but it does a jolt", said Ekström Professor.

From May & # 39; this year, Mayotte has been subject to what is known as "earthquake swarm"; grouping & # 39; hundreds & # 39; seismic events over & # 39; days or weeks, but activity decreased by & # 39; significantly in recent months.

Analysis of the French Geological Survey suggest that strange waves may indicate a mass movement & # 39; magma under the earth's crust, such as chamber collapse.

The rimitiku movement, such as sloshing molten rock, or wave & # 39; pressure tirribetti of the magma body have the potential to resonate with & # 39; similarly for reading & # 39; Mayotte.

Democratic Republic of Congo was the site & # 39; a similar event in 2002, where waves & # 39; low frequency and & # 39; low frequency like it was linked & # 39; room & # 39; magma which comes under the Nyiragongo volcano.
