Revised and additional geocentric coordinates of seismological stations

Abstract

The authors have included in a recent paper [Gerl. Beitr. Geophys. 40 (1933) 380] a list of selected seismological stations with carefully verified coordinates, including geocentric latitudes and heights above an arbitrary sphere. Comparison with the publication by K. E. Bullen (The Constants of Seismological Observatories, 1933) revealed certain discrepancies, which have been investigated by direct correspondence with the stations concerned. In the interval a few stations have removed to new positions, or have themselves revised their published coordinates, and other new installations have been made which justify the inclusion of additional stations in a selected list.
