Motion of Earth's surface caused by volcanic activity
The "Serapium" or Macellum of Pozzuoli demonstrated the effects of bradyseism.
Bradyseism is the gradual uplift (positive bradyseism) or descent (negative bradyseism) of part of the Earth's surface caused by the filling or emptying of an underground magma chamber or hydrothermal activity, particularly in volcanic calderas. It can persist for millennia in between eruptions and each uplift event is normally accompanied by thousands of small to moderate earthquakes.[1] The word derives from the ancient Greek words βραδύς bradús, meaning "slow", and σεισμός seismós meaning "movement", and was coined by Arturo Issel in 1883.[2][3][4]
