abstract = "{The main focus of this paper is to assess the feasibility of utilizing
dedicated satellite gravity missions in order to detect large-
scale solid mass transfer events (e.g. landslides).
Specifically, a sensitivity analysis of Gravity Recovery and
Climate Experiment (GRACE) gravity field solutions in
conjunction with simulated case studies is employed to predict
gravity changes due to past subaerial and submarine mass
transfer events, namely the Agulhas slump in southeastern Africa
and the Heart Mountain Landslide in northwestern Wyoming. The
detectability of these events is evaluated by taking into
account the expected noise level in the GRACE gravity field
solutions and simulating their impact on the gravity field
through forward modelling of the mass transfer. The spectral
content of the estimated gravity changes induced by a simulated
large-scale landslide event is estimated for the known spatial
resolution of the GRACE observations using wavelet
multiresolution analysis. The results indicate that both the
Agulhas slump and the Heart Mountain Landslide could have been
detected by GRACE, resulting in |0.4| and |0.18| mGal change on
GRACE solutions, respectively. The suggested methodology is
further extended to the case studies of the submarine landslide
in Tohoku, Japan, and the Grand Banks landslide in Newfoundland,
Canada. The detectability of these events using GRACE solutions
is assessed through their impact on the gravity field.}",
