摘要：Man ventured out of the caves nearly 15000 years ago and since then tried to explain earth vibrations as mythology. Naturally occurring earthquakes were observed and described over the last two thousand years. Though the Universe is nearly 14 billion years old and the trillions of celestial bodies are continuously colliding, sending gravitational waves passing energy to bodies like micro-earth that are responsible for tectonic plate movement on this macro-earth and earthquakes, the effects are recorded over two years ago. Ever since scientific revolution in 17th century machines became ubiquitous and their vibrations are felt in every day’s life. This paper summarizes these vibrations.
