Detecting
earthquakes and nuclear explosions
Cyril
Isenberg, University of Kent.
The science
of seismology is only a hundred years
old. In this time the study of
seismic waves produced by earthquakes has
enabled the solid-liquid-solid structure
of the Earth to be established. The Apollo
missions to the Moon in the 1970s
and the Viking mission to Mars set up
seismometers on the surface of these
planets to determine their internal
structure using the same techniques
developed on Earth. Considerable research
has also been undertaken to distinguish
small nuclear underground explosions
from earthquakes in order to be able
to distinguish between them. Some attempts
have been made by countries to mask
underground nuclear explosions so that
they mimic earthquakes. The lecturer
will demonstrate and explain seismic wave
propagation .
Dr Isenberg was a student
and research fellow in
theoretical solid state physics at
King's College London before taking up an
appointment as Resident Research Associate
at the Argonne National Laboratory
in the USA in the 1960s. He subsequently
joined the academic staff of the Physics
Department of the University of Kent. He
is well known, nationally and
internationally, for his
lecture-demonstrations in physics and the
organization of the annual national
British Physics Olympiad competition
for A2 students. He received an MBE
in 2008 for his outreach activities
in physics .
