| Summary | The course covers two areas of seismology: Part I covers Wave theory and Part II Earthquake Seismology. The course content is given in more detail in the syllabus below. |
| Course description |
Part I: Wave Theory
Fundamentals of wave motion; seismic wave types. Stress tensor, strain tensor, stress-strain relations; linearised equations of motion; elastic moduli.
The wave equation: dilatational and rotational solutions; separation of variables; plane and spherical waves.
Reflection and refraction of plane waves at a plane boundary; independence of SH and P and of SV waves; boundary conditions; P, SV and SH waves incident at the free surface of a homogeneous half-space and at general interfaces; energy conversions.
Rayleigh waves for a homogeneous half-space; Love waves for a two-layer half-space. Superposition of plane waves, group velocity, dispersion. Free oscillations, toroidal and spheroidal modes.
Part II: Earthquake Seismology
Introduction to Earthquake Seismology - an example from a recent event.
The Earthquake Source: Focal mechanisms, moment tensors, source time function.
Earthquake Mechanics: Friction and fracture, populations, dynamics, scaling.
Seismic Recording: Sensors, recorders, networks and arrays.
Seismograms: Natural and synthetic, time and frequency domain, combined influence of source, ray path, recording site and instrument.
Earthquake Location: Ray parameters (arrays) and the Geiger method (networks).
Global Earth Structure: Layered structure from travel time tables, 3D structure from seismic tomography.
Seismotectonics: Distribution of seismicity in space, regional stress and strain tensors, relationship to tectonics.
Seismic Hazard: Time-independent and time-dependent, can we predict individual earthquakes?

| Feedback |
Students will be provided with feedback during the course during tutorial sessions and one formative joint presentation on a case study earthquake, including peer review. Teaching staff will respond to requests for information by email and through the LEARN portal, with any queries arising from individuals communicated to the whole class. Students will be invited near the end of the course to provide formal feedback to staff on course delivery. |

Learning Outcomes
On completion of this course, the student will be able to:
- A thorough, critical understanding of advanced seismology and the range of techniques employed in this field.
- A detailed understanding of earthquake seismology
- A detailed understanding of wave equations and their solutions
- An ability to offer professional level insights because much of this course is informed by recent developments.
- An ability to critically review and consolidate this knowledge in tutorials, two formative exercises and the degree exam
