IN the course of a lecture delivered recently before the Rigaku Kyokai, or Science Society of Tokio, on the causes of earthquakes, Prof. Milne classified the theories as to the cause of these phenomena into three kindsunscientific, 7z/tfjzscientific, and scientific. In the former class he ...
As scientists learn more about the causes of earthquakes, they become better able to predict them.First of all, they know that quakes are _1_ to occur in areas where the tectonic(地壳构造的) plates push _2_ each other. They _3 these areas closely, using different instruments. They _4_...
In layman’s language, an earthquake is the shaking of the earth by some sudden underground activities. The most of theearthquakestake place along thePacific Ring of Firewhich covers the coastal region of the Pacific. Causes of Earthquake The tectonic plates in the earth’s crust are the main...
A letter in which astronomer John Flamsteed expounded his unusual views about the causes of earthquakes survives in a number of drafts and copies. Though it was compiled in response to shocks felt in England in 1692 and Sicily in 1693, its relationship to the wide range of comparable theories...
Earthquakes are the most lethal of all natural disasters. What causes them Geologists explain them in terms of a theory known as plate tectonics. Continents are floating apart from each other, this is referred to as the continental drift. About sixty miles below the surface of the sea, there...

In this article, we will look at the causes of earthquakes around the globe. What is an earthquake? An earthquake is the vibrations of the earth when the surface begins to move as a result of a sudden release of energy. This sudden release also known as a seismic wave is caused by mov...
