Two earthquakes occurred on the 10th of October in Galicia.

The first one was the strongest, with an intensity of 3.2 degrees on the Richter scale. It took place in the Atlantic Ocean, next to the Death Coast, at 9:30 p.m.

A few hours later, specifically, at 11:28 p.m., another earthquake took place in the Atlantic Ocean; but this time closer to the coast and with an intensity of 2.1 degrees.

However, these weren’t the only earthquakes that happened that day. There were two other: the first one in Zafarraya (Málaga), with 3.4 degrees; and the other one, in Salar y Loja (Granada), which was the second of that day and the third one in a series of earthquakes that happened in just three days in that zone.

Also, a third earthquake took place in Galicia the next day, in As Nogais (Lugo), with an intensity of 1.5 degrees.

Why do these earthquakes occur? Because if we think about it, Galicia isn’t an area characterized for them, and if there is any, it is usually soft, because the continental crust of our zone has a large percentage of granite on its composition and it is difficult to move it a lot. In the last 15 years, there were just about 80 earthquakes of more 2 degrees on the Richter scale.

The reason of these movements is the divergent boundary between the North American and the Eurasian plate, because minor earthquakes are one of the characteristics of these boundaries as the tectonic plates move apart.

In the last 15 days the IGN (Instituto Geográfico Nacional) detected two earthquakes in Galicia thanks to the seismographs.
The epicentre of this first earthquake was located the 9/10/15 in the latitude: 43.4725 and in the longitude:-9.6420, 5 kilometres underground in the Atlantic Ocean near to Galicia at 19:30:19. The magnitude of this earthquake was 2.7 and affected the ocean and some points of the galician coast.

The persons who live in this cities didn’t feel the earthquake because the magnitude of it was low and didn’t cause any slight damage.

The epicentre of the second earthquake was located the 14/10/2015 in the latitude : 43.1867
and in the longitude : -9.0233, 11 kilometres underground in Laxe at 22:17:30.The magnitude of this earthquake was 3.2 and affects places near to Laxe, Malpica , San Roque, Zas, Vimianzo and Caramiñas.

Some persons who live in this area felt the earthquake because some objects in their houses started to move which produced some slight damages.

Visit to the Natural Museum

On Tuesday 3rd February, we went to Santiago with the departments of French Language and Bilingual, where we visited LaSalle’s theater to watch a play in French. Then, before lunch, we went to the Natural Museum, where the French pupils were guided by our teacher in this language. And we, the bilingual pupils, stayed in a room of rocks and minerals, because we were preparing the Geologic Olympic Games, and we need to know a lot strange names about geology.
We also met Sarah Phillips, who is Ana’s friend, and she guided us in English through the different exhibitions like a huge map with the most common rocks in Galicia’s different regions, a big mockup of the soil or models of crystallization (with about three thousand pieces!).
The thing that I liked the most was the different colors of the rocks that were there. My favorite rock is the agate, and there was a pretty one there.
There were a lot of beauty minerals and crystals, and we enjoyed the tour so much.

OImagen4ur Biology and Geology teacher talked us about an Olympic Games related to geology, where a lot of Galician High Schools will show they knowledge about rocks, tectonic plates, minerals… Why? Because of the prize.

If you win this Galician phase, you will go to Alicante, to the Spanish Olympic Games, with all-expenses paid. And if you win the Spanish one, you will travel to Brazil, in the worldwide phase! And the best of all, if you win in Brazil they will give you a scholarship to go to Hawaii to study volcanoes for a year! Amazing, isn’t it?
So we went to Santiago, to the Biology Department of USC after studying almost every day to be the best and to win. Yes, we knew that we were not going to win, because we are in 4th of ESO and th
Imagen2e people in 2nd or 1st of BAC have more classes and they studied geology more time than us, but we worked a lot to try to pass the test.
We were four: Samuel, Inés, Iván and me. Alberte wanted to be there to, but he lost the raffle.

The first test we did was in groups. They gave us a map and four questions to answer, like the scale and the percentage of slope. Then, they gave us a rock and a mineral, and a photo of a fossil and a landscape with a geological phenomenon. We had to explain and identify each image or each thing. I think this p
art was easy because we made a great team. We met another of Ana’s friends: Margarita Smyth. We were so pleased to meet here!
Then, after lunch, we had the individual exam. It was such a difficult test! Then, while the jury was
correcting our exams, we visited the microbiology labs, near to the Biology Department. They were so interesting.
Then, at six o’clock we went back to the room where we did the exams and the
y announced the winners; all the winners were from Rosalía High School…Imagen2

But we learned a lot and I’m sure that, next year, my mates will do a great job and they will win, even if I’m not here!

The Dress, was the more commented in several weeks. If we talk about “The Dress” everybody will know that we are talking about the most famous dress in the world, the most polemic dress in the history of humans, and also the topic most discImagen4ussed in the last years.

What colour is this dress? What do you think? The girl, who asked her friends about the colour of the dress, didn’t think that this could separate the entire world in two teams “White and Gold” and “Black and Blue”. She decided to upload the image into the interne, because her friends cannot determine the colours. Most families in Spain and in many countries, had a huge trouble, it was an illogical discussion. Some famous people and singers have also talked on the social networks, giving their opinion.

People tried to find the solution saying that the colour depends on the screen of the mobile, tablet or computer but scientists had the solution, the culprit is our brain, it’s just an optical illusion. It depends on our eyes and our retina, objects don’t have an specific colour it depends on how the humans see the world. The people who see the dress white and gold is because their brains associate that when the photo was taken the dress was covered by a dark shadow, so their filters tried to compensate for this; changing the dark colours to light colours. But the people who see it in black and blue it’s because their brains work in a different way, and they interpret that there’s more light on the image so they change the colours, in the opposite way of the other people.Imagen5

When the owners of the shop, where the dress was sold, discovered all this trouble, they published the images of their magazine, where we can see that the real dress is black and blue. The shop triplicates their benefits only in two days.

The last 11th of February I have been in a Olympiad about Geology in Santiago de Compostela with three of my classmates, some weeks ago our teacher tell us if we wanted to go to this contest, although we knew that we would have to work a lot we decided to accept the “challenge”. Besides we knew that all of the participants would be older than us and they would be better prepared, just because they had some months to study and we only had some weeks; this was the main disadvantage. Even so, we tried to be the best group.
When we got to the Santiago, we had to go Imagen2to the Biology College in order to meet Ana, our biology and geology teacher. This “competition” was only for people from the province of A Coruña, there were eighty students from different cities and towns. It consisted in two exams, the first was in group and the second one was an individual test.
In the first part we listened to the organizer of the activity and then we had to do an exam about maps, then we had to identify some rocks and minerals, it was a lit bit difficult but then we had time to relax, because it was the time to eat. When we finish we went for a walk, just to think in other things. At three o’clock we had to start the individual test, this was even more hard than the first one, probably most of my answers will be wrong but I tried to do the best I could. After this we visited the labs of the college and we attended some explanations one of them about the soil, because 2015 is the year of soil. When they talk about soil we learnt a lot of things some of them we have learned it the previous week in a trip to a natural history museumImagen3 in the same city.
The winner of the Olympiad will go to Alicante to represent Galicia in a national contest, and there were prizes to the best students, I mean, with the best marks in the exam. The winner was a student, who was older than us and from Santiago.
I think it was a good experience for our future, the next year I would like to go again, and I will be better prepared. In my opinion the Universities must do activities like this for students, this way they can have an idea of what they want to study when they finish compulsory education.

In February we went on a trip to Santiago de Compostela, the capital city of Galicia, where there are a lot of different things to do and to see, such as the Cathedral, the city centre or different museums, in fact, we visited one of them, the Natural History Museum. This museum was so interesting because there we could learn many different things, about the biodiversity, about the geological aspects of Galicia, the soil, etc…

The same day of the visit we went to La Salle, where we could see a French play, called “Le fantome de l’opéra”, after this we went to Las Cancelas, a huge shopping centre, where we had lunch. In the afternoon, we went to the Park “Vista Alegre”, and the museum was situated here. Some years ago, when I was in sixth year of primary school, we visited the museum but it was in a different place, inside the Chemistry College. Last year the town hall opened the new building which has more than 25.000 species of animals and plants from all over the world, and they are organized depending of the continents and the habitats where they are from.
There, we met Sarah Philips, an English teacher, that showed us around the museum, and then she helped us to complete a worksheet about the rocks, the minerals and the soil. The soil is one of the most important things on our planet, it allows us to live, it’s our way of life, and we must protect it. Every year we lose hundreds of square meters, due to the expansion of the cities.Imagen1
After the explanation of Sarah, we had a free time, so we visited the rest of the collections. In my opinion it’s a good place to visit, especially for people who are interested in biology and geology. They have everything very organized so it’s so easy to search for something.

Imagen1Last week we went to the Biospain Congress of Santiago de Compostela, it´s an international congress of biotechnology where a lot of people that work or only likes this world can go and see all the stands with machines, new products and presents for the public, a lot of presents for the public.

We left the school at 8:45 and at 9:20 other students of other school got on in the bus because we had to snone it (not enough money). When we arrived at the building of the congress our teachers introduced us to the other pupils of the Pondal, it was a very embarrassing situation, and we couldn´t ask them their telephone numbers!!! (Thank you Ana and Angeles!!)

Then, a woman presented something about what we were going to see and we entered to the event building with our partners. The first thing which we did was the stand of the principal partner, I remember that was the Xunta or from the Spanish goverment.

We walked to all the congress with the woman explaining something about each stand. After these 3 presentations about biological things started and we had permission to be there. They were 30mins each and these were three, total 1h 30mins. The first  conference attended was about the reaction of the body to artificial organs, the second we attended was about another problem related with the human body and the third we attended was about 3D printers and their role in our health

The final part was my favorite part because we could visit the congress with total liberty, the first thing that we did was have a coffee from the buffet because we were very tired!!

It was very interesting and funny, I hope that we will be in another congress!!!Imagen2

BIOSPAIN 2014: Santiago de Compostela.

The last 26th of September we visited Biospain, the biggest congress about biotechnology in Spain. It was organized by Asebio (Asociación Española de Bioempresas). This congress was celebrated in Santiago de Compostela, the capital city of Galicia. This was the 7th international congress, in Spain.

Each year it is celebrated in a different place, one year it is in South America and the next year is performed in Spain. A lot of companies participate in this meeting of biotech, companies from Spain and from all the world, because this way they can advertise them and they also share information with people who is interested in this topic. We could see many varied stands from companies related with things such as; agriculture and medicine.

 Most of them told us something about the thing that they have discovered or they have improved and why they do this. We learnt many uses for biotech, now we know that this is really useful and very important nowadays.

After the visit to the stands we assisted the conferences and some spokesman from important companies explained to us what are they working on now. One of the most important topics was the 3D Printers, they are going to print organs to transplant, this has a lot of advantages, for example this way you don’t need donors. The technology is developing all these machines but they also need a medical component to have the appropriate results.

One of the problems that all of them have is the financing and they cannot improve in some things because the companies don’t share information.

In my opinion they should work together to advance faster. I think most people don’t know many things about biotechnology and about the advances of these companies. Biotech is important in almost all fields and it also can help the people. So, thanks for Asebio and all the companies that are working with biotech. The next year this meeting will be in Chile, I hope that many people can assist, if they visit this place they will learn new things.

Annik Gilles, clinical audiologist at the University Hospital of Antwerp, has presented a study in which it is reported that 20 percent of teenagers perceive a permanent ringing in the ears. This is because we are always listening to music too loud.

Annik Gilles carried out an experiment with 4000 teens. Here they’re the results:

-Only the 5% of the adolescents prevents the loss of the hearing.

-The 75% of us have temporal ringing in the ears.

This is because we use earphones with too loud music and during a long time, and we don’t prevent the damage of the ears. But, how? Using earplugs when we are swimming, listening to music at a

reasonable volume, do not use cotton swabs to clean them or keep clean your ears.

The lack of concentration, problems sleeping, irritability, are for example some of the consequences of continuous ringing in the ear. However the main problem is the total loss of the hearing, and other problems of the balance.
