He wrote: of the 1980 earthquake in Irpinia, Italy (Spence et al 1982). The Irpinia mission led to the realization of the value of “There is little room in Engineering Seismology carrying out field investigations as soon as possible after for ‘armchair seismologists’.

The mission also gave rise to the main guiding principles of EEFIT.
