  • [1] Mid to low southern latitude hydrophone stations within the Indian Ocean have recorded two distinct types of low-frequency (<100 Hz) tremor that can be correlated with drifting icebergs and glacial features along the Wilkes Land coast of eastern Antarctica. The most common of these signals is a variable harmonic tremor (VHT), with spectral peaks that exhibit frequency fluctuations through time. These signals typically display a 4 to 10 Hz fundamental frequency and may have as many as ten… CONTINUE READING
