Foreword
Measurable earthquakes occur very frequently in many parts of the world. For
example, Shepherd (1992) lists 7283 earthquakes recorded in the Caribbean Antilles
in the 22-year period 1964 to 1985, a rate of about 1 earthquake per day. Some were
due to movements of highly stressed rock at more than 100 km below the ground
surface (Shepherd and Aspinall, 1983). Similar high levels of activity are found in
all seismically active regions of the world.
As the earthquake vibrations travel from the source towards the ground surface,
the energy spreads out and also dissipates, so that energy density reduces with dis-
tance f
