The fearsome and unknown failure of Cascadia

The failure of Cascadia may not be as well known as the San Andres fault, but the truth is that it can be as or more lethal than the latter.It is estimated that it can cause earthquakes above 9 degrees and tsunamis that devastate the coast, as happened in 2011 in Japan.

The fearsome and unknown failure of Cascadia

The Cascadia fault is located off the northwest coast of the United States.It is an underwater fault that has an approximate length of 1,100 km.It covers from the province of the British Columbia to Northern California.

The Cascadia fault is not as well known as that of San Andres, perhaps this is because it has not been active in relatively recent years.In fact, according to a study of coastal sediments, pu do establish that the last mega-earthquake that generated this fault occurred in 1700 .

This submarine fault is in the well-known Pacific Fire Belt , place in which 90% of the earthquakes in the world occur.In addition, several researchers have estimated that Cascadia has shaken the earth about 40 times in the last 10,000 years with average intervals of 500 years , although they clarify that in some occasions it has happened in intervals of 200 years.

Scientists estimate that the last earthquake caused by this fault should range between 8.7 and 9.2 degrees.One of the most important aspects Terrorism of Cascadia is that the earthquakes caused by it have a high probability of being greater than 9 degrees , in addition to causing a tsunami that will take the entire coast.

The fearsome and unknown failure of Cascadia

Experts believe that if there is a total breakdown of the fault the consequences would be gigantic.In fact, it is estimated that this earthquake is the worse natural catastrophe facing the United States.It is estimated that the victims would exceed the number of 13,000 and not only because of the devastating effects of the seism, but also because of the subsequent tsunami.It is estimated that the gigantic Waves will collide with the coast just 20 minutes after the earthquake.

Researchers do not believe that the United States is prepared for an earthquake of this magnitude.They go on to take preventive and educational measures so that the population is better prepared, even more taking into account that the last earthquake caused by Cascadia occurred more than 300 years ago.

And you, did you have knowledge about the existence of this fearsome fault?

This factor is No. 1 when trying to maintain and improve your social relationships

One of the fundamental factors for all human beings, after solving the most elementary needs such as food and housing, is that of human relationships; and that is one of the senses of the famous phrase of Aristotle that defined us as "political animals", that is, animals that need to live in society. That is why it is so important to maintain and improve your social relationships , something that is not always easy to achieve, especially if you do not know this simple rule that we will talk about next. This factor is No.1 when trying to maintain and improve your social relationships Emma Seppala is Scientific Director of Research and Education for Compassion and Altruism at Stanford University, and author of several books on human relations and the elements that favor or hinder these interactions. For example, in terms of the most basic relations-and at the same time complex-between humans, such as those between men and women, Seppala does not agree with the psycholo...

Why do we hear "hidden messages" when listening to music backwards?

Have you ever heard music backwards? What do you think happens? In today's article we want to talk to you about what, in the 60s, became a fad. In 1969, Beatles fans had the strong conviction that one of their leaders, Paul McCartney was dead and this fact was being hidden from public opinion. The evidence supporting that belief was the "mysterious messages" that were hidden in the lyrics of his songs when they were heard backwards. In the song "Revolution 9" you hear the phrase "excite me, dead man" in English when the audio is played in reverse.That is one of the messages that made believe that McCartney was dead.But even if all these statements have been categorically denied, we can still find videos on YouTube with Beatles songs played backwards.Have you heard any? If you do, you will realize that these messages are clearly there, another thing is that they mean what they say they mean. Then, if we listen to those messages when we hear th...

The most abundant bird on the planet

On a previous occasion Science Daily Online I published an article about a curious variety of chicken, which was 100% black.Now we will talk a little about the origins of the chicken and how it dispersed throughout the world. "In writing hen one" In Around the day in eighty worlds the writer Argentine Julio Cortazar included a brief science fiction story, in which a chicken tells how, thanks to a NASA experiment, her sisters become intelligent and decide to take over the planet, even if they still do not control the syntax. It is not something that should be completely disdained, if we consider that at this time there should be approximately thirteen billion chickens, roosters and chickens , which makes this species the bird more abundant s work the land. Lineage and history The Gallus gallus domesticus is a subspecies of the wild bird Gallus gallus , from the family of the Phasianidae , which inhabited Southeast Asia.The current roosters and chi...

What does a volcanic lightning sound like? It has been registered and it is not as we thought!

As we have said on more than one occasion, nature often surprises us in the most terrifying way that it knows.One of those ways is, without a doubt, the eruptions of some volcanoes, one of the events more impressive and fearsome that our planet can offer us .The eruption of a volcano is terrible, suffocating, noisy and also usually covers the entire terrain around a dense and thick fog accompanied by ash that can even last several weeks They can also be accompanied by some volcanic lightning , which can add a few electric fireworks and a great deal of noise to a whole spectacle, in itself ostentatious. Catching a volcanic lightning Scientists, to date, even knowing their existence, haven't h They had never heard a volcanic lightning due to the volcano's own thunder, but finally, in March 2018, the research team led by Matthew Haney of the US Geological Survey managed to register a authentic and terrifying volcanic thunder .Although it is something that is scientific...

Why do we remember the pain?

Like many other great findings about science, the discovery about the reasons we remember the pain was a coincidence.From these first Discoveries have conducted different research on pain and suffering as well as on pain memory and chronic pain . In 1954, two researchers at McGill University in Canada accidentally discovered how humans learn to repeat a behavior that is beneficial for our survival. An electrode implanted in the brain of a rat had slipped from its intended place and stopped in the medial beam of the anterior brain , a group of nerve cells that reach from the depths of the brain to the prefrontal cortex.After receiving a series of desc electric argas , the rat showed great interest in the area where he had been exploring when he received the first jolt. At first, the researchers, James Olds and Peter Milner, they thought they had found the region of the brain responsible for governing curiosity. But after conducting further research, Olds and M...

The terrible Tuskege experiment against syphilis

The Tuskegee experiment is one of the most enlightening evidence that human cruelty has no limits.This clinical study appears between 1932 and 1972 was honored to the title "Turk's head." The story you are going to read It will seem like science fiction but it is not.Of course it is not. The Tuskegee experiment: the inoculation of syphilis in an illiterate population of Alabama For most of the century XX, the black population remained in a situation of semi-slavery.They were the ones who performed the worst jobs, had no right to education and were completely marginalized from Caucasian citizenship. Therefore, Dr.Taliaferro, creator of the experiment, did not have no scruple when recruiting more than half a thousand men to perform what was supposed to be a chance to get r free health. All these patients were never informed that they were undergoing an experiment to find out if syphilis medications (very aggressive at that time) were really useful or if their ef...

When the world smells like nothing: anosmia

I have a friend, let's call him Jesus, who after ten years fell from a wall and hit him hard on the head that led him to the hospital, where he took some stitches and examined him carefully to rule out major injuries.Apparently it was fine, and it would be several years before he realized that he did not perceive odors, that in the coup he had lost one of the apparently innocuous senses with which we connected to the world: the sense of smell; loss that the medicine calls anosmia . Thirty years later, after overcoming a bad cold, Jesus discovered that his ability to smell the world had returned, and since then no He has stopped celebrating it in various ways, for example, doing cooking courses and experiencing new dishes with smells and flavors whenever he can and his financial resources allow it. This is not the case with Boak Duncan, native of Leeds (United Kingdom), that after suffering a serious head injury, also due to a fall as a seven-year-old boy, he lost his sense o...
