From: Monthly GRACE detection of coseismic gravity change associated with 2011 Tohoku-Oki earthquake using northern gradient approach

Figure 3

Model-predicted and synthetic-data-retrieved northern (latitude-direction) component of coseismic gravity gradient changes due to 2011 Tohoku-Oki earthquake. (a) Model prediction with 300 km Gaussian smoothing only. (b) Model prediction with P3M6 destriping and 300 km Gaussian smoothing. (c) Model prediction with Duan09 destriping and 300 km Gaussian smoothing. (d) Northern gravity gradient changes between the mean of 2 years before and after the earthquake, computed from the synthetic monthly GRACE observations (with seasonal and trend terms removed by time series fitting), with P3M6 destriping and 300 km Gaussian smoothing. (e) The retrieved northern gravity gradient changes same as (d) but with Duan09 destriping and 300 km Gaussian smoothing.
