Advanced LIGO and the next generation of ground-based detectors aim to
capture many more binary coalescences through improving sensitivity and duty
cycle. Earthquakes have always been a limiting factor at low frequency where
neither the pendulum suspension nor the active controls provide sufficient
isolation to the test mass mirrors. Several control strategies have been
proposed to reduce the impact of tele-seismic events by switching to a robust
configuration with less aggressive feedback. The continental United States has
witnessed a huge increase in the number of induced earthquake events primarily
associated with hydraulic fracking-related waste water re-injection. Effects
from these are differ from teleseismic earthquakes primarily because of their
depth which is in turn linked to their triggering mechanism. In this paper, we
discuss the impact caused due to these low magnitude regional earthquakes and
explore ways to minimize the impact of induced seismicity on the detector.
