An earthquake that occurs underwater, causing vibrations and sometimes tsunamis in the ocean.
Blend of 'aqua' (Latin for water) and 'quake' (Old English cwacian, meaning to shake). This modern coinage combines the two elements to describe seismic activity in aquatic environments.
While 'aquake' isn't standard scientific terminology, geologists actually use the term 'submarine earthquake' for the same phenomenon—but aquake captures something poetic about how the ocean itself trembles, creating some of Earth's most dramatic natural disasters.
