A spring tide—popularly known as a "King Tide"—refers to the 'springing forth' of the tide during new and full moon. A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other.

19 Οκτ 2023 · Tsunamis are caused not by tides, but by underwater earthquakes and volcanoes. Tsunamis are associated with tides because their reach surpasses the tidal range of an area. So-called “ red tides ” also have nothing to do with actual tides .
28 Σεπ 2024 · neap tide, tide of minimal range occurring near the time when the Moon and the Sun are in quadrature. This condition is geometrically defined as the time at which the line from the Earth to the Moon is at right angles to the line from the Earth to the Sun.
7 Ιουν 2019 · The tides are turning in a quest to solve an earthquake mystery. Years ago, scientists realized that earthquakes along mid-ocean ridges — those underwater mountain ranges at the edges of the tectonic plates — are linked with the tides.
What is a neap tide? When the sun and moons are at right angles to each other, there is least gravitational pull, meaning the tidal range is at its lowest. The neap tide occurs 7 days after the spring tide. A neap tide is where the sun and moon are at their least aligned point. Not to scale.
When the Sun is at a right angle to the Moon, moderate tides, called neap tides, result. From our view on Earth, these tides coincide with certain lunar phases since they occur when the Moon reaches specific positions in its orbit.
20 Δεκ 2006 · Neap tides occur when the Sun and Moon are aligned at right angles from the Earth at first- and third-quarter phases of the Moon. The result is that spring tides are higher than neap tides (Fig. 1 E). The period of time from new Moon to new Moon is called the synodic month, which has a modern period of 29.53 days.
