WebJan 18, 2024 · The GRACE mission has contributed to the seismic characterization of major earthquakes in offshore regions of the world. Here, we isolate satellite gravity signal (μGal range) for the Japan Earthquake of 2011 using a difference method. Contrary to the existing gravity models, we propose a unit vertical pyramid based five-layer 3-D thrust fault … Web3. GRACE Gravity Model Quality Validation [11] Satellite orbit fits are one traditional measure of the gravity model accuracy. This is a particularly demanding test for the GRACE models because Earth gravity models have previously depended on the tracking to various geo-detic satellites to determine the low degree part of the field,
