Global seismology is a science driven by observations, and most major advances in our discipline can be linked to advances in the quality and quantity of seismic instrumentation. Normal-mode seismology was born in the early Sixties, when Caltech and UCLA seismologists identified fundamental toroidal and spheroidal modes in spectra obtained from time series recorded after the great 22 May 1960 Chilean earthquake. In the Eighties, the Harvard centroid-moment tensor project was initiated, and global tomographybecame feasible as a result of high-quality data recorded by the International Deployment of Accelerometers (IDA) and the Global Digital Seismographic Network (GDSN). Today, the Global...
