Detection of earthquake early warnings

In News 
  • Scientists have developed a novel experimental framework in fluid dynamics to describe deformation in disordered soft solids formed by mixing solid grains at significant proportions in a simple liquid which can help in developing early warning systems to minimize damage due to catastrophic events like landslides/earthquakes.
About the Experiment 
  • These systems are comprised of grains that are essentially similar to grains of rice.
  • Rice grains can be packed better into a container by shaking the container.
  • The forces coming from shaking make the grains gradually more compact until it reaches a critical degree of compaction.
  • Interestingly, such critical compaction encodes the information about the interactions between the grains coming from inter-particle friction, the shape of the particles, sticky-ness, and so on.
  • A group of researchers from Raman Research Institute, an autonomous institute of the Department of Science and Technology has proposed a novel experimental framework.
