N2  - Seismicity associated with the Koyna Reservoir, western
Maharashtra, is unique because it is one of the few
sites in the world where earthquakes of M ? 5.0 continue
to occur three decades after the initial spurt of
activity. This contrasts with most other seismogenic
reservoirs where temporal patterns of seismicity are
characterized by one or two peaks that taper-off with
time. Persistence of moderate seismicity at Koyna is
enigmatic, considering also the low seismic productivity
of the peninsular shield. Temporal association of
major earthquakes with annual reservoir loading has
been observed for long. In this paper, we report a discernible difference between the spatial pattern of
earthquakes associated with the reservoir loading and
unloading. A conceptual model is proposed to explain
the continued occurrence of earthquakes.
