should be high it will be more cost effective to do without geophysical
survey. On the other hand, where a large area must be covered in detail
(especially in oil prospecting) but high accuracy is not essential,
geophysical survey can be used. Besides, the choice of the particular
geophysical method requires consideration of a number of geological,
economic, safety, security factors and taking into account
environmental concerns.

My name is Steve Holbrook. I am a geophysicist here at the department
and the kind of work I do – is seismology, particularly active source
seismology which means … the two types of seismologists, the kinds that
listen for the sounds that the Earth makes, earth seismologists. The second
kind which I am, which is the kind of seismologists who do not wait for
