Long-period tides are gravitational tides with periods longer than one day, typically with amplitudes of a few centimeters or less. Long-period tidal...

tide constituents are almost identical. At neap tides the semi-diurnal tide is virtually absent, resulting in the phenomenon known as a "dodge tide"—a...

dates of spring tides and neap tides, approximately seven days apart, can be determined by the heights of the tides on the classic tide tables: a small...

seismicity has three major forms: short-period earthquake, long-period earthquake, and harmonic tremor. Short-period earthquakes are like normal fault-generated...
