GS-Paper-1 Geography- Earthquake (PT)
According to a recently published study, researchers have developed a new way to improve the prediction of earthquakes.
Vibrations from an earthquake are categorised as P (primary) and S (secondary) waves. They travel through the Earth in different ways and at different speeds. They can be detected and analysed.
Earthquakes usually occur along faults (fractures between rocks which can range from a few millimetres to thousands of kilometres). When two blocks of earth slip past one another, seismic waves are generated in a short span of time and earthquakes occur. The waves travel to the surface causing destruction and are difficult to predict, making it challenging to save lives.
Scientists have attempted to recreate the faults and their sliding in laboratories to try and understand the conditions in them during earthquakes.
However, the actual conditions are so complex that it is difficult to recreate them with full accuracy which makes the prediction of earthquakes difficult.
