A review and new insights on the estimation of the b-valueand its uncertainty

W Marzocchi, L Sandri - Annals of geophysics, 2003 - earth-prints.org
The estimation of the b-value of the Gutenberg-Richter Law and its uncertainty is crucial in
seismic hazard studies, as well as in verifying theoretical assertions, such as, for example …

Minimum magnitude of completeness in earthquake catalogs: Examples from Alaska, the western United States, and Japan

S Wiemer, M Wyss - Bulletin of the Seismological Society …, 2000 - pubs.geoscienceworld.org
