    Geology of tides

    Are earthquakes and/or volcanic eruptions more likely at spring tide than neap tide?

    To the best of my knowledge, no. If tidal deformation does trigger such an event once in a while, I would think of it as the straw that broke the camel's back, that is, perhaps hastening by a few seconds a fault slip that was about to happen anyway.

    In non-scientific language, a definite maybe.

    https://en.wikipedia.org/wiki/Tidal_...of_earthquakes

    Wiki article in link abpve.

    Google "Earth tides and earthquakes" also.

    It requires very careful statistical analysis and locational tidal analysis.

    (edit) And WRT your OP, neither, corellation appears to be WRT in between tidal highs and lows.

    I'm not a hardnosed mainstreamer; I just like the observations, theories, predictions, and results to match.

    There is a fortnightly cycle at the San Andreas, but the peak occurs during the upstroke in fortnightly tide strength, when the rate of change of tidal force is fastest.
