| contents | Evolution of b-values before large earthquakes of mb≥6.0 in the Andaman region SHWETA PRASAD CHANDRANI SINGH Ciencias de la Tierra value Gutenberg Resolution Richter relation Andaman earthquake We have considered six earthquakes of m b ≥6.0 in the Andaman region (2000-2012), with focal depths within 45km, to examine the spatial variations of b-value at epicentre within a one-year period prior to the occurrence of the earthquakes. We have found a correlation between the low b for the one year time interval and the occurrence of large events. The epicentral b-values of six earthquakes are lower than 1.0 and five out of six earthquakes show very low b-value at the epicentre. Our study indicate that b-value may be employed to forecast a major earthquake. 2015 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50541392003 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.3 Vol.13 |
