Abstract

A primary objective for next-generation gravitational wave detection is to extend the sensitivity to low frequencies for pre-merger detection and early electromagnetic warning. The main obstacle is the ambient seismic noise. Current detectors benefit from passive and active vibration isolation on the local scale aimed at vibration control of the test masses individually. I discuss some techniques to improve low-frequency ambient seismic noise measurements below 10 Hz. The results are seismic noise site characterization at Gingin and seismic array configuration optimization that provide real time awareness of the low-frequency seismic environment using array seismology to develop global and efficient vibration isolation.
