Short summary
We provide a comprehensive overview of the content in terms of moment magnitude (Mw) in the Bulletin of the International Seismological Centre (ISC). Mw is the preferred magnitude to characterize earthquakes in various research topics (e.g. Earth seismicity rates) and other applications (e.g. seismic hazard). We describe first the contribution of global agencies and agencies operating at a regional scale and then discuss features of Mw via different sets of comparisons.
