Abstract

Do have earthquakes anything to do with oscillations? The question naturally arises since the phenomenon of earthquake appears to be a random, chaotic and unpredictable one, while the term oscillation seems to indicate more towards a periodic and hence predictable event. But we shall presently see that in spite of this apparent contradiction, at least some aspects of earthquakes can indeed be understood better in terms of a particular type of oscillation discussed later. Understanding the dynamics of any system is the primary condition for making any prediction about the system. The efforts to explain tectonic plate movement in terms of oscillations is not absolutely new [1] as we shall soon see, but the present approach is a new effort in this direction with the help of some simple table-top experiments based on apparatus like pressure-cooker and pop-pop boat.
