                                                         Earthquakes

Earthquakes can be defined as the shaking of the earth’s surface which is caused by sudden release of energy creates seismic waves that travel through the earth. It involves the powerful movement of rocks in the Earth’s crust. The largest earthquake ever recorded was a magnitude 9.5 in Chile on May 22, 1960. The destructions caused by earthquakes have an impact on roughly 8,000 people each year and have caused an estimated 13 million deaths in the past 4,000 years. The largest recorded earthquake in the world was a magnitude 9.5 in Chile on May 22, 1960.

Quick Facts: –

  • The 2011 earthquake near Japan increased the Earth’s rotation speed, shortening the day by 1.8 microseconds.
  • The fastest wave, and therefore the first to arrive at a given location, is called the P wave.
  • Aftershocks occur because the displaced fault line and crust are adjusting to the effects of the main earthquake.
  • As per the Japanese mythology, a giant catfish is responsible for the occurrence of an earthquake.
  • A tectonic plate movement of just 20 cm is enough to set off a major earthquake. They move less than 3 inches per year.
  • According to scientists, the animals may sense weak tremors right before an earthquake.
  • Parkfield, California, is known as ‘The Earthquake Capital of the World’ and has a bridge that spans two tectonic plates.
  • The initial point of an earthquake is called hypocenter and the point at ground level above the hypocenter is called epicentre.
