IPA: /ˈsiːkweɪk/
KK: /siːˌkweɪk/
A type of earthquake that occurs beneath the ocean floor.
The seaquake caused massive waves that affected the coastal towns.
Seaquake → It is formed from "sea" (from Old English "sǣ", meaning large body of saltwater) and "quake" (from Old English "cwacian", meaning to shake or tremble). The word "seaquake" refers to a shaking or trembling that occurs in the sea, typically due to seismic activity.
Imagine the sea shaking or trembling — that's what a seaquake means, combining the large body of water ('sea') with the action of shaking ('quake').
