Annals of the International Geophysical Year, Volume 30: Seismology is an eight-chapter text that provides seismological data observed during the International Geophysical Year (IGY). The resolution to include seismology in the IGY program has considerably stimulated seismic researches and accelerated the development of nets of seismic stations in many countries. After a brief introduction to seismological stations and equipment, this book goes on dealing with the approved proposal of the U.S.S.R. to establish three seismological stations in the Arctic zone and recommended to other nations that maintain seismological stations in that zone. A chapter presents the microseismological activities observed in various regions, emphasizing their geographical differences. Other chapters present a summary of special seismic crustal studies during the IGY to examine Earth's crust and Antarctic structures. The final chapters contain data on long period waves and the Lg phase, as well as the measurements of the Earth's crust strain. This book will be of value to geophysicists and researchers in the field.
