Summary The reading of earthquake diagrams is discussed with special reference to the readings made at individual seismological stations and collected in the International Seismological Summary . It is argued that the most useful readings would result if observers fixed on the really well marked phases only. Interpretation of such phases usually can easily be obtained when the travel times of an earthquake are collected. Minor phases, on the other hand, quite often do not correlate and cannot be interpreted with any certainty. Attention is drawn to the important phases characteristic of epiceatral distances and diagrams are presented.
