Malayalee scientist's discovery in predicting quakes
Observing the data of tectonic turbulence of Parkfield along the San Andreas Fault in California, something interesting struck a team of scientists led by Malayalee researcher Deepa Mele Veedu. It showed a complex deformation style and a possible connection.Â
Â
An isolated tremor source near Parkfield has been producing low frequency quakes in a particular pattern. The tremor pattern oscillated between three and six days in mid 2003 culminating in an earthquake of magnitude of 6.0 in 2004.Â
Â
Till then, scientists believed that moderate intensity tremors below two on Richter scale will not result in massive quakes. Â
Â
The team from Nanyang Technological University (NTU) at its Earth Observatory of Singapore (EOS) led by Deepa has now come up with a path-breaking find that prediction of large quakes is possible, even by observing low vibrations. Â
Â
A release from NTU says slow fault movements or vibrations point to an impending earthquake and these movements also have a discernible pattern. If carefully monitored, even the particular patterns in low-intensity tremors could also be used to predict powerful tremors. A research paper on this has been published in the Nature magazine.Â

Deepa Mele Veedu holds a masters degree in marine geophysics from Cochin University of Science and Technology and M.Tech in exploration Geoscience from IIT Kharagpur. She completed her degree in Physics from Kannur University. A Ph.D scholar at NTU, Deepa is currently working on slow ruptures shortly preceding the 2011 Tohoku-Oki earthquake in Japan and the 2014 Iquique earthquake off the coast of Chile. Â Â
