Comparison of crustal and upper mantle heterogeneity in different time periods: Indonesian subduction zone to northern Australia

Sun, Weijia; Fu, Li-Yun; Kennett, Brian


Earthquake events from the Indonesian subduction zone recorded in northern Australia show a long and high-frequency coda associated with both P and S waves. Regional events recorded by Warramunga array in northern Australia can separate out wave propagation through the mantle by focusing on the coherent signal across the medium-aperture array. Most of the incoherent wave components result from structures in the vicinity of the array with small-scale lengths of 1-2 km or smaller. The coherent...[Show more]
