我们提出了三种稳态火山活动期间的岩浆收支模型，通过这些模型，未喷发的岩浆以岩脉或堆积或结晶的形式就位。利用气体和热数据，我们在Vulcano应用我们的模型来计算岩浆在40-375 kg s−1的速率下的脱气、冷却和结晶，岩浆体的上表面深度为~ 2 km。在Stromboli，我们计算出300-1300 kg s - 1的稳定岩浆供应到浅（<1 km）深度。
We present three models for magma budget during steady‐state volcanic activity, by which non‐erupted magma is emplaced as dykes or cumulates or crystallises in place. Using gas and thermal data we apply our models at Vulcano to calculate degassing, cooling and crystallisation of magma at a rate of 40–375 kg s−1 within a magma body with an upper surface at a ∼2 km depth. At Stromboli we calculate a steady magma supply of 300–1300 kg s−1 to shallow (<1 km) depths.
