Relating to or caused by slow, gradual movement of the Earth's crust.
From Greek 'brady-' (slow) and 'seismos' (earthquake), with suffix '-ic'. This adjectival form emphasizes the earthquake-related but gradual nature.
Bradyseismic movements are the sneaky tectonic shifts we rarely notice—but they reshape coastlines over human timescales, which is why old harbors worldwide are mysteriously flooded or exposed.
