Correctly interpreting complex scattered wavefields to recover meaningful information about a medium is one of the most fundamental issues broached by seismologists. Such studies encompass the full spectrum of frequencies presented by seismic signals, and methods to identify coherency from otherwise...

Correctly interpreting complex scattered wavefields to recover meaningful information about a medium is one of the most fundamental issues broached by seismologists.

This body of work investigates the use of two different branches of scattered wavefield experiments conducted on very different scales. Works detailing high frequency coda-related seismic interferometry applied to Erebus volcano on Ross Island, Antarctica, and P-wave receiver functions applied to the whole of West Antarctica are developed, with a variety of innovations and implications for future imaging efforts.
