We estimate the mechanical strength of the Indonesian active continental margin. Values of
effective elastic thickness (Te) were obtained for azimuthally averaged coherence
measurements γ2 (| k|) between Bouguer gravity and topography using a multitaper method
with Hermite tapers. The Te estimates reveal uniform low strength (4–7km) beneath the
entire Indonesian continental margin. The 2D coherence function γ2 (| k|) estimated with the
help of MTM reveals varying anisotropy in the Indonesian margin and illustrates how the …
