several ways of detecting earthquakes

The reading and the lecture are about various ways to detect earthquakes. The author of the reading feels that earthquakes can be identified by animal behavior, headaches of people, and radon emission. However, the tutor challenges all the points made by the author and elaborates hereunder. First of all, the professor implies that predicting earthquakes by the behaviour of animals is not true. He further elaborates by saying that animals react even for a mild shaking of the ground, on which we cannot rely on them. He also adds the point that minor shaking will not emphasize an earthquake. Moreover, the minor change will not lead to earthquakes. On the contrary, the reading posits that earthquakes can be identified through animal behavior as they have sensory abilities. Secondly, the passage mentions that earthquakes can be predicted by the headaches occurring to people. As the human brain has a mineral called magnetite, this mineral will predict the changes in the electromagnetic field by causing illness to people. On the other hand, the tutor argues this point by saying that headaches are the rarest symptoms of earthquakes. Even more, a human brain has a minute amount of magnetite where its sensitivity is barely influenced. Finally, the academician implies that measuring radon emissions is not a practical way to predict earthquakes, because radon can be emitted through various impacts like man-made destruction processes or even with an impact of rock fracture. Furthermore, he says that relying on radon emission is just responded to false alarms. This particular point is contradicted in writing. The writing indicates that by measuring radon emissions will be helpful in detecting the earthquakes as most of the rocks emit radon before an earthquake hits.
