摘 要: | We analyzed the International Seismoogical Center(ISC)catalogue of seismologil publicationsfrom 1980 to 1995 to investigate how much infonformation provided by an earithquake hes beenutilized to obtain a better undertanding of earthauakes and selsmic disaster.We sekect the ISCbulletin which has a wider coverage of seismological journals and languages than the ScientificCitation Index(SCI),so that there is less regional or language bias in the analysis.The earth-quakes in the catalogue span the period from 1975 to 1990.Papers which have direct relationwith an earthquake as defined by the ISC catalogue range from 1 to 10~2 in order of magni-tudes.The logarithm of the maximum number of papers on an earthquake is shown to be prop-ortional to the magnitude of the earthquake,which provides a possibility to define a“normali-zed impact strength”of an earthquake,so that earthquakes with different magnitudes can becompared with each other.Magnitude span of the earthquakes with a certain“impact strengthlevel”an
