The article “A ’64 Quake Still Reverberates” brings up an really important issue about the recent quakes that hit the West coast of the American continent.In 1964, an devastating earthquake with the magnitude of 9.2 hit the South-central region of Alaska, and kills 125 people.This was the second most powerful earthquake after the one in Chile in 1960, that had the magnitude of 9.5 degrees.2014, 50 years after the earthquake in Alaska, a quake hits the coast of Chile, with a magnitude 8.2, killing 6 people.According to new reachers, the Chile`s 2014 quake was caused by the reverberations of the ’64 earthquake in Alaska.The Chile`s earthquake happened along a fault where stresses had been building.These stresses were caused by the slowly dipped beneath one plate and another, according to scientists.They call it the low-angle megathrust event.Along 50 years , the quake in Alaska that caused stress on the fault, and aggravated it , reflecting in earthquakes as the one that rocked Chile.
It is important to know about geology, and understand how the tectonics plate system works.This plates are what cause the earthquakes, and understanding them can maybe help to forecast a big or even normal earthquake that is coming up.To people,specially those who live near geologic faults, its is also important to be aware about it because earthquakes affect many people, specially those who are not prepared, as for example, the earthquake in Haiti in 2010, which killed hundreds of people.
The article written by Henry Fountain describes with a lot of details how do the tectonic plates work.It also give a lot of examples that helped to understand it.I liked how they mention the details of the research and explained how did scientist came to such conclusion.
Pedro did a great job on his review of the article, A '64 Quake Still Reverberates. I liked how he did a brief summery of some of the major earthquakes on the west coast like the one in Chile and Alaska. In addition, I also liked how he explained how the earthquake in Alaska caused stress on the fault which then affected Chile. I also liked how he explained why knowing this was important because earthquakes affect many people and knowing more about them, can save lives.
ReplyDeleteThere were a few things that Pedro could have improved on. For instance, some of his sentences were slightly confusing, even though the message still came across. Another thing that could be improved on was explaining more on how tectonic plates work. Other than these small details, the review was still very good.
From reading this article, I learned that earthquakes long ago can still affect more recent ones. This is important because maybe that scientists now know this information, it can help them predict where earthquakes might happen. Knowing this can save many lives and limit a lot of destruction.
Pedro did great on this article review. I like that he summarized other earthquakes. I also liked that he explained that the 2014 Chile earthquake was caused by the 64 earthquake in Alaska. It seems unlikely that a geological disaster happening in Alaska years ago could cause an earthquake recently.
ReplyDeleteThere was only one thing he could have changed. For example, there were some wording mistakes. But that doesn't matter because he still did well.
I did not know that the recent Chile earthquake was caused by an Alaskan earthquake decades ago. That comes off as a bit strange because they are two different places and two different years. But I learned that Alaska and Chile and other countries are believed to be connected in a formation known as the ring of fire
