According to a recent study, elastic properties and the ability to endure aggression of earth is changed even if an earthquake is observed 6000 kilometers away. Researchers stated that the earth is a spherical ball of an interconnected and interlinked system, where any event occurring at any place has a measurable or unmeasurable effect at any other place, even if these two places differ by 6000 kilometers and if the event may be a large earthquake. These quakes are the reason behind all the major tsunamis, if the hypocentre is below water surface
Earth is a made up of tectonic plates that always keeps on moving slowly but measurably. If in any case these tectonic plates slides or strikes on any other then a big and series of earthquake is observed. The tectonic plates are on the lithosphere, the outer and the only visible shell of the earth. There are seven major tectonic plates in mother earth namely, African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate.
The research headed by Kevin Chao, a postdoc in Massachusetts Institute of Technology’s Department of Earth, Atmospheric and Planetary Sciences, who is also a member of a research team led by Andrew Delorey at Los Alamos National Laboratory. Chao stated that earthquakes are in the form of waves (known as ‘Seismic waves’) keep on moving to infinity with a decreasing amplitude, starting from the hypocentre. It’s just that the effect of these waves can be observed by a seismograph only up to 6000 kilometres. It takes almost 3 weeks for the earth to recover its elastic properties.
“When surface waves pass through, all of these properties rearrange and change. If a fault with high stress is ready to fail, it will accumulate more stresses in the fault, meaning an earthquake could occur at any time,” Chao said.
