"The fundamental work of Beno Gutenberg has inspired and guided an appreciable part of research in modern seismology both from the experimental and the theoretical point of view. Among the several topics of seismology that have benefited from the fundamental contribution of Gutenberg we consider particularly relevant the description of the asthenospheric low-velocity channel the definition of the surface waves magnitude and the Gutenberg-Richter law since they are pivotal tools for seismic hazard assessment. The quite revolutionary model for the lithosphere-asthenosphere system in the European area predicts the existence of almost aseismic lithospheric roots. These roots are located in correspondence of most of the orogenic belts and interrupt the asthenosphere low velocity channel that has been identified by Beno Gutenberg in 1948. The model of the European upper mantle proposed for the first time in 1979 and subsequently refined has stimulated a considerable amount of research which has nicely confirmed the major innovative features of the early model. At present the subduction of the lithosphere at continent-continent collisions supported not only by seismological data is a widely accepted concept within the community of Earth scientists even if it contradicts one of the basic dogmas of the original formulation of plate tectonics. The proposed model for the Alpine-Apennines area supplies a new and unifying framework for the interpretation of the Quaternary magmatism at present generally accepted by petrologists and geochemists. The fundamental work of Beno Gutenberg has inspired and guided most of the research in modern seismology both from the experimental and the theoretical point of view. For a comprehensive review of the activity of the foremost observational seismologist of the 20th century see Knopoff 1999. His earliest and most famous achievement is the accurate determination of the depth of the Earth's core Gutenberg et al. 1912 Gutenberg and Geiger 1912 Gutenberg 1913 Gutenberg 1914 that represented the starting point for his numerous contributions to the study of the Earth system like the investigation of the physical properties of the solid Earth e.g. Gutenberg 1924 Gutenberg 1943 Gutenberg 1959 the continental drift model e.g. Gutenberg 1927a Gutenberg 1927b Gutenberg 1930b and the models of the atmosphere e.g. Gutenberg 1926 Gutenberg 1930a."

Earth-Science Reviews55/1-2 2001 pp. 165-180 Beno Gutenberg 1889 -1960 made several important contributions to the science. He was a colleague and mentor of Charles Francis Richter at the California Institute of Technology and Richter's collaborator in developing the Richter magnitude scale for measuring an earthquake's magnitude. unknown
