Les signes d'avertissement avant les catastrophes peuvent souvent apparaître dans la nature ou dans votre environnement. Par exemple, si vous remarquez des animaux quittant soudainement une zone ou se comportant de manière étrange, cela pourrait être un signe d'un tremblement de terre ou d'une tempête imminente. Une chute soudaine des niveaux d'eau à la plage pourrait signifier qu'un tsunami approche, il est donc important de se déplacer rapidement vers un terrain plus élevé. Si vous voyez des fissures se former dans le sol ou entendez un rugissement fort, cela pourrait être un signe précoce d'un glissement de terrain. Sentir du gaz à l'intérieur pourrait indiquer une fuite, ce qui est un avertissement pour quitter immédiatement les lieux et appeler à l'aide afin de prévenir une explosion. Prêter attention à ces signes peut vous donner une longueur d'avance pour atteindre la sécurité avant qu'une catastrophe ne frappe.

00:00When we see a rainbow, it is often interpreted as a foretaste of luck.
00:05Conversely, the vision of an abyss fish is generally considered as the sign of imminent misfortune.
00:11Let's explore together these ancient legends and the meaning they could have in modern life.
00:19In August 2024, the Californians began their day as usual.
00:24The radiant sun encouraged them to go to the beach to enjoy the beautiful weather.
00:28They went kayaking and diving, when one of them suddenly noticed something unusual.
00:34A very bad-luck fish.
00:37The creature, measuring nearly 4 meters, was a regalec.
00:41A fish of which only about twenty specimens have failed on the Californian coast since 1901.
00:47Inhabiting the dark depths of the ocean, they are often associated with an imminent disaster.
00:52But why?
00:54According to Japanese folklore, these creatures would be announcers of disasters.
00:59Once considered as sea snakes, they are nicknamed the messengers of the palace of the seabed.
01:05They would leave this majestic place only to warn humans of the ravages to come.
01:10And this is why regalecs are perceived as sinister signs.
01:13Their appearance is often followed by a tsunami or an earthquake.
01:17The oceanographers themselves recognize the reputation of this disturbing association.
01:23This is where things take a strange turn.
01:26The regalec failed near the coast of San Diego on August 10.
01:30Two days later, on August 12, a magnitude 4.4 earthquake hit Los Angeles.
01:36And this phenomenon is not new.
01:38In 2011, in Japan, about 20 regalecs were found to have failed along the beaches and coasts of Tohoku.
01:44Shortly after, a magnitude 9 earthquake and a tsunami hit the region.
01:49A similar incident occurred in the Philippines.
01:52On February 8, 2017, a regalec was spotted.
01:56And two days later, a magnitude 6.7 earthquake shook the city and neighboring provinces.
02:02Of course, it is impossible to prove that these events are truly related.
02:06The Seismological Society of America insists that it is only superstition.
02:11And a recent study, having analyzed these coincidences,
02:14concluded that this association had no statistical foundations.
02:19But can we say that there is really no causal link?
02:23For centuries, humans have observed that animals adopted strange behaviors just before natural disasters,
02:30whether they are earthquakes, floods or even tsunamis.
02:34It is as if animals perceive signs that are invisible to us.
02:37In reality, this theory is supported by many scientific studies.
02:42These show that animals are able to perceive subtle environmental changes,
02:47such as fluctuations in the terrestrial electromagnetic field or infrasons.
02:52Elements that humans cannot discern.
02:54This is explained by the fact that most animals have a more extensive auditory range
02:59and particularly refined senses that allow them to detect gases emitted by the earth.
03:05This theory became popular after the devastating 2004 tsunami,
03:09which ravaged several cities and villages in Indonesia.
03:12Most of the alarm systems designed by humans have ceased to work,
03:16failing to warn the population of the imminent disaster.
03:20Some sensors were out of service due to maintenance work,
03:24while other coastal areas were devoid of any tsunami alarm system.
03:28A very sad competition of circumstances.
03:31However, in the minutes and hours before the arrival of the 9-meter wave,
03:35some animals perceived the danger and fled.
03:39Witnesses report that elephants rushed to the heights,
03:43pink flamingos left their nests at low altitudes,
03:46and dogs refused to leave.
03:48A resident observed a herd of buffalos turning their ears to the sea
03:52before launching into the top of a hill.
03:55Many survivors of the tsunami relied on animal reactions as warning signals.
04:00And it was not the first time that man had used animals to save his life.
04:04The first official account dates back to 373 BC.
04:08Although we were not there to see it,
04:11the Greek historian Thucydides reports that rats, fowls and snakes
04:15were seen fleeing the city before a massive earthquake occurred.
04:19So what can animals perceive and humans do not detect?
04:23To find out more, scientists set up biologging beacons
04:27on cows, sheep and dogs living in Italy.
04:31For about six months, they followed these animals.
04:35During this period, more than 18,000 earthquakes were recorded in the region.
04:39What is most surprising is that animals began to change their behavior
04:43up to 20 hours before an earthquake occurred.
04:47Before an earthquake, a phenomenon called a positive hole occurs.
04:51An electric charge rises from the earth's crust to the surface.
04:55This phenomenon alters air molecules in affected areas
04:59and animals seem to be able to detect these signals.
05:02Indications also suggest that animals could detect changes in the phreatic naps.
05:07Before earthquakes, the pressure on the fault lines can release radon,
05:12a gas capable of modifying the chemical composition of underground waters.
05:16Animals dependent on these resources could thus perceive these variations
05:20and react accordingly.
05:23Birds are also particularly sensitive to magnetic field fluctuations
05:28that can occur just before an earthquake.
05:31Another study was carried out near Mount Etna,
05:34one of the most active volcanoes in the world, located in Sicily.
05:37In 2002, a violent eruption destroyed a TV set,
05:41two hotels and several shops near Etna.
05:44Over the years, a group of researchers has undertaken
05:47to monitor the behavior of the goats living on the edge of the volcano.
05:50Their great discovery came in 2012,
05:53when the goats began to behave erratically
05:56about six hours before a new lava eruption.
05:59Scientists have thus been able to predict, retrospectively,
06:02nearly seven disasters in two years.
06:04And all thanks to goats.
06:06In 2014, a group of researchers studying the golden-winged parrots of Tennessee
06:11observed a singular phenomenon.
06:14The birds had suddenly deviated from their usual nesting sites.
06:18These little migrators have traveled 700 km since the Cumberland Mountains,
06:22where they had just arrived after a journey of more than 4,800 km
06:26from South America.
06:28Shortly after the departure of the parrots,
06:30a series of more than 80 tornadoes fell on the region,
06:34causing damage of more than a billion dollars.
06:37The researchers qualify this behavior as evacuation migration.
06:41The birds would have perceived the tornadoes at more than 400 km away.
06:45Infrasounds are key indicators of natural disasters.
06:49Storms and tornadoes generate extremely powerful infrasounds,
06:52capable of traveling over thousands of kilometers.
06:55These are very low frequencies, located below 20 Hz.
06:59Human hearing does not allow us to capture these sounds.
07:02Indeed, our hearing is located between 20 and 20,000 Hz.
07:06This means that we can perceive very low sounds,
07:09such as a deep bass,
07:11up to high-pitched sounds,
07:12such as the buzzing of a mosquito near our ear.
07:16Elephants, for their part, can hear frequencies below 20 Hz,
07:20which makes them experts in disaster detection.
07:24Scientists also believe that the ability to perceive infrasounds
07:27helps birds to avoid storms during their oceanic crossing.
07:32The Pacific Ocean, far from deserving its name,
07:35often reserves violent storms to the brave navigators
07:38who dare to cross it,
07:40and that their satellite instruments can not always detect.
07:43The National Museum of Natural History of Paris
07:46is currently working on a project to follow more than a hundred birds
07:49during their annual crossing of the Pacific.
07:52With the support of the International Space Station,
07:55researchers are trying to understand how these birds react
07:58to natural disasters along the way.
08:00But this idea is not unanimous.
08:02Some scientists say that,
08:04although animals are sensitive to environmental variations,
08:08it would be risky to predict disasters
08:10based on their behavior.
08:12The Institute for Geological Studies of the United States
08:15notes that the majority of observations of unusual behavior
08:18before disasters remain anecdotal,
08:21and that large-scale studies have not yet established direct links.
08:25Although we do not have extraordinary abilities
08:28to anticipate disasters,
08:30some clues may nevertheless warn us of the danger.
08:33For example, if you find yourself in an area where lightning is imminent,
08:37your hair may warn you while standing up.
08:40This phenomenon indicates that lightning is heading straight at you.
08:43So do not waste time and run to shelter.
08:46Enter a building, if possible.
08:48It is the best reaction to adopt in such a situation.
