Earlier this month, the seismic stations from Madagascar to Canada caught mysterious waves broke more than 20 minutes, pointless for most people.
Researchers and enthusiasts & # 39; earthquakes have seen signs reduced the origins region & # 39; the offshore island of Mayotte, in the Indian Ocean.
But, no one quite sure what caused the strange event.
The waves slowly discovered by Mayotte in 11 & # 39; November are those typically seen after major earthquakes, and are known to travel great distances – but, there was no earthquake like this.
Researchers and enthusiasts & # 39; earthquakes spotted signs reduced the origins region & # 39; off the coast of Mayotte island (shown), in the Indian Ocean. But, no one quite sure what caused the strange event
"I do not think I have seen anything like this," said Göran Ekström, sismologu of & # 39; University & # 39; Columbia who specializes in & # 39; unusual trasmuni, told National Geographic.
But, he adds, "Do not say that, ultimately, their case is exotic".
Twitter Wall brought the attention of seismology community first showed strange phenomenon in the morning of 11 & # 39; in November.
Wall & # 39; Twitter has brought attention from the community of seismology first showed strange phenomenon in the morning & # 39; November 11. Scientists and enthusiasts earthquake left to decrease it
"This is a seismic signal the most odd and unusual". Twitter @matarikipax user wrote along with & # 39; reading & # 39; sismografu from Kilima Mbogo, Kenya.
Over the course of & # 39; that day, others can blur the conversation to indicate where else the waves were detected & # 39; Low frequency: Chile, New Zealand, Canada and Ħawajja.
Signs created waves emerged from Mayotte clean, b & # 39; żigżagġ design primarily & # 39; one type & # 39; wave, it took 17 seconds to repeat, according to National Geographic.
like waves that are known as monochromatic.
The strange waves were traced to a home about 15 miles off the French island, Mayotte
Scientists are working to understand what triggered the mysterious waves in & # 39; that day. S & # 39; now, many suspect to be related to & # 39; continuous seismic swarm in the region began in & # 39; last May.
But even then, there was no corresponding earthquake on 11 & # 39; in November.
The researchers with the French Geological Survey (BRGM) say they can & # 39; be a sign that magma under the volcanic island is moving offshore.
Others say they have & # 39; there was an earthquake "slow" that just went by unnoticed, or underwater eruption.
"The confirmation of tqiegħedha place near the Comoros", the researchers who made the discovery say.
Experts say that the complex geology of the region continued to issue further, potentially filtering few waves to make a clean signal, NatGeo reports.
Scientists plan to investigate the ocean to find additional information & # 39; help explain the mysterious phenomenon.
But in & # 39; this stage, experts agree that there is very little to say we do not know what really was at fault.
HOW WOULD MEZJAR BY THIRD COUNTRIES?
The magnitude of & # 39; earthquake is different from its intensity.
The magnitude of & # 39; earthquake refers to the measurement of energy released in the earthquake originated.
The size is calculated on the measurement on sismografi.
The intensity of & # 39; earthquake refers to how strong stirring to the feeling.
Earthquake & # 39; equal to 5.3 hit the Channel Islands of the Southern California coast on Thursday at 10:30 am
According to the US Geological Survey, "the intensity is determined by the effects on people, human structures and the natural environment".
Earthquakes originate below the earth's surface in & # 39; region called the ipokentru.
During an earthquake, one part of & # 39; sismof remains stationary and one part moves with the face of the earth.
The earthquake then be measured by the difference in the positions still and moving parts of sismografu.
