> the tidal force caused by the full moon.

Is that real? Doesn’t seem like it would matter enough. Especially when there was an eruption, why even mention it.

Yes, it's real. Tides are higher around the full moon due to the earth, sun, and moon being (roughly) aligned. If it was already high tide, adding a tsunami on top of it is going to be more impactful than at low tide.
