**EESC 4949**, Introduction to Seismology (2009)

**http://www.ldeo.columbia.edu/~ekstrom/Courses/EESC4949**

** Course Summary**

Presents an overview of the field of seismology, with a focus on
elastic wave propagation in the Earth and Earth structure.
Phenomenology and physics of seismic body waves, surface
waves and Earth's normal modes. Seismic sources and
seismometry. Seismological constraints
on the structure of the Earth's interior and properties
of the crust, mantle, and core.

**Suggested preparation**

Calculus, differential equations, Fourier series,
college physics.

**Topics**

- stress, strain and the wave equation
- body waves
- surface waves
- normal modes
- seismic sources and noise
- seismometers
- Earth structure; radial density, elastic
and anelastic structure of Earth's
mantle and core. Mantle discontinuities
and mineralogical phase transformations; elastic anisotropy;
partial melt. Lateral heterogeneity of Earth's mantle and core.

** Class Format: **

The course meeting time will mainly be used for informal
lecture presentation. Additional section/lab time will be
scheduled to introduce basic seismological software tools
needed to complete some of the problem sets, and to provide
some hands-on experience working with seismic data.
There will be assignments and exams.
