Last week, the world has produced three earthquakes of a magnitude of 7 degrees and even higher. One of them took place in Myanmar, second in Japan and most powerful in Ecuador. In the world, there are two methods used to prevent loss of life from major earthquakes and installation of devices that warn sound at the time of the earthquake, which warn those ar greater distance from the epicentre with seconds before the quake to strike the region.
Approximately 80% of all earthquakes occur along the Ring of Fire, curb demarcating the Pacific, and there is no less than 452 volcanoes, around 75% of active volcanoes on Earth and slept. Natural events eruptions or meteorite impact can cause earthquakes, but most occur due to movements of continental plates. Earthquakes that occur in a part of the Earth can shake the other side of the planet.
Researchers who have studied the earthquake in 2004 that generated tsunamis in the Indian Ocean, they found that the earthquake has weakened at least a portion of the San Andreas fault in California. 1960 earthquake in Chile generated tremors for several days over the entire surface of the Earth.
An earthquake can not be predicted at present. However, a modern invention can become the solution for saving the lives of people living in areas of high seismic risk. It uses satellites to measure electromagnetic signals that occur when the eartquake is about to occur. A small group of researches has used satellites to study the ionosphere, the upper atmosphere, which is full of electrically charged particles.
They have observed changes in the level of these particles even up to 10 days before the earthquake devastating. The changes we have seen include a lot of electromagnetics signals from the air conductivity, before changes in electromagnetic fields. Scientists can not say, but certainly causing these signals, but have some doubts. The relevant hypothesis is that when the pressure builds up and deform the crust are released small amounts of radon, which is trapped in air pockets.
Radon is radioactive and may give rise to the release of some of electromagnetic signals from the ionosphere. These can be measured both on the ground and in the air, but satellites cover a much larger area.
Scientists from the Mullard Space Science Laboratory at University College London, plan a space mission to test this hypothesis. They hope to can send two satellites into orbit small bottom of the Earth that can capture these signals.
If this method will fuction, earthquakes can be predicted a few hours before their production, thereby saving a lot of lives. There are, of course contesters of this idea, saying that earthquake prediction is impossible. Countries where earthquakes are indeed a problem, such as the United States or Japan, have tried over the years to develop such mechanisms for anticipating earthquakes, but failed. It takes a successful example of this because this kind of ideas to be considered.
This technology use GPS Phone Tracker, which can locate all people under the ground and they can save all.
