Relationships Among Magnitudes and Seismic Moment of Earthquakes in the Taiwan Region
The seismic moments (Mo), body-wave magnitudes (mb), and surfacewave magnitudes (Ms) of 201 Taiwan earthquakes with 4.8 ≤_nmb ≤_n6.6 published in the Global CMT catalog from 1976 to 2006 are used to study the correlations among the three source parameters. The resultant relationships are: log(Mo) =...

| description | The seismic moments (Mo), body-wave magnitudes (mb), and surfacewave magnitudes (Ms) of 201 Taiwan earthquakes with 4.8 ≤_nmb ≤_n6.6 published in the Global CMT catalog from 1976 to 2006 are used to study the correlations among the three source parameters. The resultant relationships are: log(Mo) = (1.07 ¡__n0.04) Ms + (18.72 ¡__n0.20); log(Mo) = (1.73 ¡__n0.09) mb + (15.09 ¡__n0.52); and Ms = (1.46 ¡__n0.08) mb - (2.52 ¡__n0.43). The three relationships have high agreement with those of earthquakes in the circum-Pacific seismic belt. This might imply that the tectonic conditions and source properties of the Taiwan region behave like the average ones of the circum-Pacific seismic belt. The relationships between the three source parameters and local magnitude are: log(Mo) = (1.27 ¡__n0.06) ML + (17.23 ¡__n0.35); mb = (0.66 ¡__n0.03) ML + (1.69 ¡__n0.17); and Ms = (1.03 ¡__n0.06) ML - (0.53 ¡__n0.36). |
