Seismic moments of Taiwan’s earthquakes evaluated from a regional broadband array
Earth, Planets and Space volume 60, pages 559–564 (2008)
Abstract
We have taken the seismic moment (Mo) values of 79 earthquakes occurring in the Taiwan region that have been published in the Global centroid-moment tensor (CMT) and regional Broadband Array in Taiwan for Seismology (BATS) catalogues for the period 1996–2005 and compared the values determined from the global and regional networks, respectively. MoG and MoB are used to denote the Mo values published in the Global CMT and regional BATS catalogues, respectively. Our results show that MoB linearly correlates with MoG and that MoB is, on average, approximately equal to 0.37MoG. This difference may be caused by the use of shorter period seismic waves in BATS for estimating MoB. The moment magnitude evaluated from regional BATS seismograms is about 0.3 less than that estimated from global data.
