Researchers are confused by a remarkable seismic ripple that traveled around the world on the morning of November 11th.
Seismic waves buzzed sensors from Africa to New Zealand and Hawaii for about 20 minutes, but it seems no people felt the bizarre ripple, National Geographic was reported.
Twitter users food pie discovered the strange movement on US Geological Survey graphs. He noticed a ” most strange and unusual seismic signal ” on data from Kilimambogo, Kenya, Lusaka, Zambia, Mount Furi, Ethiopia, San Pablo, Spain and Wellington, New Zealand.
The signals, National Geographic reported, resembling the long-standing surface waves that reside from earthquakes alongside other higher frequency waves. But there was no major earthquake that morning to interrupt the ripple.
Stranger still the waves were monochromatic, removed by the fuzzy noise that several different frequencies create.
“I do not think I’ve seen anything like that,” said the seanologist Columbia University at National Geographic ].
“It’s as if you have colored glasses and [are] just look red or something,” added Anthony Lomax, an independent seismologist.
Some researchers find that the strange ripple can be something to do with a seismic storm lashing Mayo TTE, an archipelago in Africa close to where the signal began. But that storm has fallen in wildness since a magnitude 5.8 tremor struck in May.
The French Geological Survey (BRGM), National Geographic stated that a new center for volcanic activity could come near the island. Magma may be on its way deep under the ocean a few kilometers from the beach.
An incredibly slow earthquake, which released stress for a long time, could also have caused the strange ripple, Ekström told the publication. Such events, which are often associated with volcanic activity, may vary from minutes to days. “Same deformation [as a regular earthquake] happens, but it does not happen like a shot,” Ekström says.
But researchers are still far from some. “It’s very hard to really say what the reason is and if someone’s theories are correct,” said Helen Robinson, Ph.D. in Applied Volcanology at the University of Glasgow, National Geographic .
Explanations as imaginative as a sea monster, a weapon test or an extraterrestrial attack have all been shared online. BGRM plans to investigate the bottom of the sea near Mayotte to see if a submarine outbreak occurred. But at the moment the huge planet-filled ripple of November 11 is still a mystery.
