Important remarks
1. We need time dependence to real time monitor the changes in elastic energy. Without time-dependent tidal effects we wouldn’t no monitor elastic (or any) changes. Sismographs arrive late!
2. We need angular resolved (TM71) information because tidal potentials are vectorial
3. Also, because I cannot see any other way to get Z-information, which is in particular the direction showing largest changes
We are unique
