SEISAN EARTHQUAKE ANALYSIS SOFTWARE FOR WINDOWS, SOLARIS, LINUX and MACOSX Version 10.0 Editors Lars Ottem¨oller(1) [email protected] Peter Voss(2) [email protected] Jens Havskov(1) [email protected] (1) Department of Earth Science (2) Geological Survey of Denmark and Greenland University of Bergen Øster Voldgade 10 Allgaten 41 1350 Copenhagen K 5007 Bergen Denmark Norway http://seisan.info July 2013 2 Cover The figure on the cover show a screendump of a new Seisan Expolorer function, that show the relationship between estimated magnitudes. Here it is the GlobalCMT MW versus the USGS Mb, note how the Mb saturates around 6.8 [Ekstr¨omet al., 2012].
