A Mysterious Seismic Wave Recently SHOOK Earth, And Scientists Can not Explain It



[ad_1]

Scientists are at a loss to explain a seismic event Strange That SHOOK-the planet on November 11 and Earthquake Was picked up by sensors stationed across the globe.

Whiles The Cause of disturbance remaini Print mysterious unknown, it's somehow linked to an Ongoing seismic swarm That's Been Archipelago-the rumbling of Mayotte in-the Indian Ocean for severals months – just pocket What These unusual tremors Ultimately signify remaini unclear.

"I do not think I've Seen Anything like it," Göran Ekström From Columbia University seismologists told National Geographic November 11 about-the anomaly.

Almost exactly half a year before Print Strange signal turned up, seismologists were surprised by Another kind of Abnormal seismic activity in the-Same Vicinity: a swarm of hundred of small and frequent Earthquakes Originating about 50 kilometers (31 miles) off the east coast of Mayotte .

Mayotte 646 mysterious vibration 2The Earthquake Swarm (BRGM)

The network of islands and islets, roughly locateds HALFWAY Between Africa and Madagascar, the governed by France, claimed by the-pocket ALSO the island nation of Comoros.

On-the morning of May 10, Print region rocked by a Quake Was That turned up without warning, and Which did not come alone – being followed by a series of hundred of tremors That have yet to Disappear.

The dramatic These must of – a Magnitude 5.8 event on May 15 – the-largests Quake Was ever recorded form the basin-the Comoros, and whiles the-swarm Has generally lessened in intensity Since, resurgences just a 5.1 Magnitude Print week served as a not-so- That subtle reminder Print earthly turbulence is not over.

Whiles Earthquake swarm sound alarming, they're not necessarily Dangerous events.

Print In case, a preliminary analysis of seismic swarm by-the-the Ecole Normale Supérieure Researchers at the Paris-the tremors Suggest BE can not alone accounted for by tectonic movement, meaning volcanic activity in-the-region must ALSO BE Involved.

Which Brings us to November 11.

Less Than Three Weeks Ago – During-the swarm, on pocket a day whens no swarm tremors were Actually detectable – Scientists Registered something to else: a Strange, long, and flat vibration That hummed consistently, without-the spiky fluctuations That are a signature of usual Quake activity.

INSTEAD, Print "atypical very low frequency signal" – to quote France's Bureau de Recherches Géologiques (BRGM) – repeated in a wave about Every 17 seconds, lasting for about 20 Minutes in total.

'There are a lot Things we do not know, "Research engineer Nicolas Taillefer, the-head of BRGM's seismic and volcanic risk unit, told National Geographic.

"It's something to Quite new in-the Signals on Our stations."

Which is not to say-the team does not have a hypothesis. With What we suspect Already about-the seismic swarm, Researchers-the-the-the best GUESS anomalous vibration Was ALSO linked to volcanic activity, the due Perhaps to a movement of magma the- Huge Indian Ocean.

If so, explain something to else Print Could ALSO: Mayotte is not stationary.

That GPS readings indicate Since July – an after-the swarm began – the island Has shifted approximately 60 mm (2.4 in) to the-east and 30 mm (1.2 in) south.

According to one analysis, movement Could BE Print to the due-the emptying of a magma reservoir Nearby, although Additional Research Would needed to verify services Print.

If out-the hypothesis TURNS To Be Correct, Nobody can say for sure What Happen mights, the-pocket modeling indicates Mayotte May keep moving as long as persists-the swarm.

As for WHETHER we'll Encounter-the mysterious signal again, Nobody know.

"These observations therefore back up-the hypothesis of a combination at-effects of tectonic and volcanic accounting for a geological Phenomenon involving a seismic sequence and a volcanic Phenomenon," the BRGM explains.

"Will hypothesis THIS NEED TO BE Scientific Confirmed by future studies."
