Weak tides can be amplified by matching timing
The strange part is the scale mismatch: the modeled stresses are comparable to a gentle hand press, yet the researchers say a fault can respond strongly when the timing matches its natural response timescale, like a swing pushed at the right rhythm. Depending on a fault’s frictional behavior and the tide’s timing and strength, the model produced slow slip and, in some cases, faster slip.
The work modeled one patch of a fault zone in isolation. It is presented as a framework for interpreting tidal patterns in slow earthquakes, not as a demonstrated method for predicting earthquakes.
