Reader in Seismology
My research in earthquake studies has
in several broad areas of observational
and theoretical seismology over the
last two decades.
The major goal of the work is to
understand the physics of the earthquake
preparation and faulting process, and
to predict expected motion at sites of
engineering interest (the built
environment) due to large earthquakes.
The long-term goal
is to prepare the physical
basis for developing the capability to
predict earthquakes, in future,
if possible. Current research is focussed
on the scaling of small to large earthquakes,
study of very large submarine earthquake
which cannot be studied by any other means
such as GPS or SAR, and study of deep
earthquakes and shapes of deep seismic
zones along with its implications
for mantle dynamics.
