00:00A giant fissure, of over 3500 km long, opens across Africa.
00:06Routes, houses, even schools, they make a mess.
00:09Today, scientists think that they have finally understood what is the cause.
00:14A huge column of burning rocks, a super panache,
00:18which goes from the depths of the planet.
00:20And it pushes slowly the earth, cm by cm.
00:25It's not a small change.
00:27The continent is divided into two.
00:30And the indices of what is happening might be hidden at thousands of kilometers,
00:34in Hawaii.
00:35And why did the United States suddenly play a role in all this?
00:38Attend a little.
00:39We will arrive.
00:40First of all, it is important to know that the information is not new.
00:44The Africa divided slowly over 25 millions of years.
00:48This is happening in a region called the Rift East African system.
00:52It extends thousands of kilometers from Ethiopia to Mozambique
00:56and it's the biggest system of Rift continental active on the planet.
01:00Here, I want to say,
01:01where the earth is empty and empty,
01:04causing problems,
01:06falling,
01:07and volcanic eruptions.
01:09It's terrifying.
01:10It's the least that we can say.
01:12In 2018, for example,
01:14a huge fissure appeared close to a small village
01:16just west of the capital of Kenya,
01:18Nairobi.
01:19At some places,
01:20it was about 20 meters wide,
01:22so almost the size of two school buses
01:25garés l'un derrière l'autre.
01:26It was absolutely terrifying.
01:28It was very quickly,
01:29and it destroyed a lot of things.
01:31The routes were cut.
01:32The fermes were devastated.
01:34The people were on the nerves.
01:35The ground was literally on their feet.
01:38An old man saw the fissure traverser his house.
01:41He barely had the time to recover
01:43some of his things
01:44before everything goes down.
01:47It's frightening, right?
01:48Because it was happening in the region
01:50of Grand Rift,
01:51in the East Africa,
01:52the panic was spread rapidly.
01:54The media were saying
01:55that it was proof that Africa was divided.
01:58The people who lived
01:59near the crevasse
02:00were told
02:00that it's right,
02:02it's happening.
02:03And many believe it
02:04today.
02:04But that's not really the case.
02:07At least,
02:08not with this crevasse.
02:09Because after the initial panic,
02:11videos and photos
02:12revealed an indication
02:14that they were not
02:15to the movement
02:16of the tectonics.
02:17First indication,
02:18the two sides of the crevasse
02:19correspond not to.
02:20Like when we look at
02:22two pieces of puzzle
02:23which do not correspond,
02:24the boards
02:25just simply aren't aligned.
02:26Second indication,
02:28the two sides
02:28were not a continuous line.
02:30There was a kind of
02:31bridge between the two sides.
02:36Some specialists
02:37croient that the fissure
02:38was once again
02:39full of volcanic sand
02:40from the mont Longono
02:42nearby.
02:42But then,
02:43the region was struck
02:44by the heavy rain.
02:46When the water
02:47was impregnated the soil,
02:48it took off
02:49the sand,
02:50making it visible.
02:51Problem resolved.
02:52But even
02:53that the truth was
02:54appeared,
02:54it was too late.
02:55This event
02:56had released
02:57all the discussion
02:57on the physical
02:58and imminent
03:00of Africa.
03:01But listen,
03:01even if this
03:02has nothing to do with this
03:04phenomenon,
03:04you don't know,
03:05Africa is
03:06quite a bit
03:08Because the continent
03:08is between two
03:09tectonics.
03:11The Somalian
03:13to the East
03:13and the Nubian
03:15to the West.
03:16The problem,
03:17it is that they
03:17separate from each other.
03:19And as soon as they
03:20separate,
03:21the river
03:21in the Rift
03:22African
03:23stops
03:25from the East
03:27and the East
03:31of the East
03:31and the East
03:33of the East
03:33of the East
03:33of the East
03:34and the East
03:35of the East.
03:36But don't worry
03:38about it,
03:39this process
03:39is super,
03:40super
03:41so long
03:41that no one
03:43of us will never
03:44see the end.
03:45The experts say
03:46that the continent
03:47moves around 0,3
03:49inches
03:49to some places
03:50to give you an idea,
03:52it's less than
03:53the length of your fingers.
03:54We can say
03:55without fear
03:56that the process
03:57will take millions
03:58of years,
03:58which is a good news
04:00for the residents
04:00of the region.
04:01But it doesn't mean
04:02that they will not feel
04:03the effects of this
04:04lento rupture.
04:05In fact,
04:06they already are produced.
04:08Let's take a look
04:09for example
04:09the region Afar
04:10in Ethiopia.
04:11In 2005,
04:13this region has shown
04:14how much the Rift
04:15could be imprevisible.
04:16In a very short lapse
04:17of time,
04:19420
04:19tremblements
04:20of land
04:20have struck
04:21the region
04:21opened up a huge
04:23fissure.
04:23What generally takes
04:24centuries,
04:25is produced in only
04:26a few days,
04:27putting completely
04:28into question
04:29what scientists
04:30thought about
04:31the speed of change
04:32geological change.
04:33At the time,
04:34the fissure
04:35extended to more
04:35than 56 km,
04:37and the life
04:38was far away
04:38to be easy.
04:39These recent tremblements
04:40of land
04:41have destroyed
04:42a large part
04:42of the local infrastructure.
04:4437 schools
04:45have been damaged,
04:46leaving
04:465,000 students
04:47without class
04:48and that is
04:49only a part
04:50of the damage.
04:52According to some
04:53predictions,
04:54such as the
04:54tectonic plates
04:55continue to
04:55disappear,
04:56the water will end
04:57inunding this region,
04:58thus creating a new
04:59ocean.
05:00These countries
05:01like the Zambie
05:01and the Uganda
05:02who are today
05:03today
05:03could have one day
05:04one day
05:05could be an excellent
05:06news for them,
05:08because it could
05:08open new routes
05:09commerciales
05:10and transform
05:11entirely
05:12their economies.
05:13But not
05:14too quickly,
05:15we will not
05:16fall into the
05:176th ocean
05:18of Sito.
05:20The process
05:21of separation
05:21will take
05:22five to ten millions
05:23of years.
05:24It is difficult
05:25to tell exactly
05:26when this will happen,
05:27because big events
05:28like the
05:29tremblements
05:30of the earth
05:30could accelerate.
05:32So,
05:33here we know what
05:33we know.
05:34the
05:36Nubian
05:37are in the middle
05:37of a spectacular
05:38separation
05:39and slowly
05:40move along
05:41the other.
05:42Africa is
05:43divided by
05:43two.
05:44The earth will
05:45probably win a new
05:46océan
05:47because of this
05:47but just recently
05:48we didn't know
05:49what caused
05:51all this.
05:51Yes,
05:52these tectonic plates
05:53move.
05:53Why?
05:55Are they
05:55Is this gigantic geological process a for cause something that happens in the earth's mantle?
06:00Or could it have a much bigger and deeper source?
06:04Well, scientists think that they may have finally resolved the mystery.
06:08They believe that the continent is fractured by the presence of a deep panache,
06:13a huge huge rock rock located under the east-african rift.
06:19Representez-vous un énorme marteau souterrain poussant vers le haut, pressant contre la croûte et la fissurant lentement.
06:26Mais voici ce qui est intéressant.
06:27Les scientifiques sont parvenus à cette conclusion grâce à quelque chose qui s'est passé dans une partie du monde
06:33complètement différente, Hawaï.
06:36Sous cet état américain, il y a aussi un panache de roches super chaude qui s'élève des profondeurs de
06:41la planète.
06:42Il fait fondre la croûte au-dessus de lui et c'est ce qui alimente les volcans d'Hawaï.
06:46Au fur et à mesure que la plaque du Pacifique dérive au-dessus de ce panache,
06:50la roche en fusion perce de nouveaux endroits, créant volcan après volcan.
06:54Au cours de millions d'années, c'est ainsi que les îles hawaïennes se sont formées.
06:59Ce panache hawaïen contient des gaz nobles, comme l'hélium et le néon.
07:03Et vous savez où d'autres les scientifiques ont trouvé ces mêmes gaz ?
07:07Et oui, sous le système du rift est-africain. Bingo !
07:11Cette découverte a renforcé la théorie selon laquelle un super panache serait à l'origine de ce qui se passe
07:16en Afrique.
07:17Nous le qualifions de super, parce qu'il pourrait être gigantesque.
07:21Vous voyez, ces mêmes gaz ont été trouvés dans des roches volcaniques du Kenya, jusqu'au Malawi.
07:28Donc, tout indique l'existence d'un super panache unique qui s'étend de l'océan Indien jusqu'à la
07:33mer Rouge,
07:34et non pas d'une multitude de sources isolées.
07:38Si leurs données et recherches sont correctes, les scientifiques estiment que ce super panache sous l'Afrique commence probablement à
07:45la limite noyau-manteau,
07:46qui se situe à environ 2900 km de profondeur à l'intérieur de la Terre.
07:51Bien que les signatures chimiques du système du rift est-africain soient similaires à celles que l'on trouve dans
07:56les roches volcaniques d'Hawaii,
07:58elles ne sont pas identiques.
07:59On pense que le panache hawaïen est un courant étroit de manteaux chauds qui montent, un peu comme le mouvement
08:05à l'intérieur d'une lampe à lave.
08:07Le panache africain pourrait avoir une forme différente et ressembler davantage à une grande masse de matériaux chauds et flottants
08:13qui s'élèvent des profondeurs de la Terre.
08:15Lorsqu'il atteint la surface, ce matériau frappe la couche extérieure, qui est froide et solide,
08:20et se répand en poussant suffisamment fort pour la fissurer et déclencher une intense activité volcanique dans toute la région.
08:27Si cette théorie est correcte, nous sommes en présence d'une force lente, mais inarrêtable,
08:33qui redessinera la carte de l'Afrique et changera le continent à jamais.
08:36...
