Washington, Jan 14: Researchers have developed a new and better method to predict earthquakes.
The system uses a micro-tremor data (data for quakes with a magnitude of between -1 and 5) to analyse and estimate the complete stress tensor and monitor changes in the magnitude of stress and the instability of faults, making earthquake predictions more valid.
For their tests, researchers used data for micro-tremors in Iceland from 1990 to 2005 and found that the stress analysis accurately predicted impending earthquakes.
“This experience from Iceland therefore indicates that the sites of coming earthquakes can be determined years before they occur. What is crucial to whether the analysis is reliable is to what extent the small quakes are analyzed," said Ragnar Slunga, the lead scientist behind the project.
"Especially if the method is to be used to warn people immediately before a coming earthquake, a few days or a few hours before the quake, it's necessary to analyse very minor micro-tremors as well," Slunga added.
The project was co-ordinated by the Icelandic seismological network. '
