Seismic imaging and properties
Contact: Dr Tim Henstock
One of the primary ways to investigate features underneath the surface of the Earth is to use seismic waves. We work with both imaging of features where we try and determine their size and geometry, and remote estimation of physical properties such as P and S wave seismic velocity or quality factor. As a group we work from from the 10s-100s of km scales of plate tectonic processes to very small scales of only a few cm. Working on new methods often runs in parallel with other research projects or the development of new equipment.

Some key aspects of our research are:
- Depth imaging, particularly using multichannel high-resolution seismics
- Tomographic determination of seismic velocity
- Waveform inversion of multi-offset data
- High-resolution 3D imaging using Chirp sources
- Assessment of attenuation in near-surface sediments
Current activities in which we are using this research include:
