Im thinking more like the 25th or the 26th. I checked my tide charts for the North bay where I live and the tides will be very big on those to days since it will be a new moon. Tides are always highest on a full moon but lately the new moon has had some big ones.

Big large high tides have always been associated with earth quakes and through research one can see that the biggest earthquakes coincide with the biggest high tides.
