Fig. 6From: Visualizing heterogeneities of earthquake hypocenter catalogs: modeling, analysis, and compensationSmoothed surfaces of magnitude differences of P&S and E&V catalogs against Abe catalog. a MP&S–MABE, b ME&V–MABE on the plane MABE against the elapsed time (1897–1980) for global earthquakes, c MABE–MUTSU, and d ME&V–MUTSU on the plane MUTSU over the period in years for Japan region. High magnitude differences are shown in purple (in contrast to than light blue). The vertical dotted lines in a–d denote 1922 and 1948Back to article page
