The macalube (or maccalube) are small mud volcanoes formed by a rare geological phenomenon called sedimentary volcanism: methane gas pressure causes gas, water, and clayey sediments to escape from the subsurface, forming mud cones very similar to volcanoes.
The term likely derives from the Arabic maqlùb, meaning "overturning" or "upside down," referring to the lifting and overturning of older materials brought to the surface during eruptive phases (from the web).
