The science of seismology is just over a hundred years old.
In this time the study of seismic waves has enabled the location of earthquakes, and more recently nuclear explosions, and revealed the solid-liquid-solid structure of the Earth.
This lecture-demonstration will review our knowledge of this field.
In the 1970's the Apollo missions to the Moon and the Viking mission to Mars set up seismometers on the surface of these bodies to determine their internal structure using the techniques developed on Earth.
The results obtained will be examined. All future explorations of the solar system will investigate further seismic studies.
These studies enable us to 'look' into the structure of the planets and their moons.
Refreshments 18:00 and afterwards.
