Volcanism is one of the main mechanisms transferring mass and energy between the interior of the Earth and the Earth's surface. However, the global mass flux of lava, volcanic ash and explosive pyroclastic deposits is not well constrained. Here we review published estimates of the mass of the erupted products from 1980 to 2019 by a global compilation. We identified 1,064 magmatic eruptions that occurred between 1980 and 2019 from the Smithsonian Global Volcanism Program database. For each eruption, we reported both the total erupted mass and its partitioning into the different volcanic products. Using this data set, we quantified the temporal and spatial evolution of subaerial volcanism and its products from 1980 to 2019 at a global and regional scale. The mass of magma erupted in each analyzed decade ranged from 1.1–4.9 × 10¹³ kg. Lava is the main subaerial erupted product representing ∼57% of the total erupted mass of magma. The products related to the biggest eruptions (Magnitude ≥6), with long recurrence times, can temporarily make explosive products more abundant than lava (e.g., decade 1990–1999). Twenty-three volcanoes produced ∼72% of the total mass, while two different sets of 15 volcanoes erupted >70% of the total mass of either effusive or explosive products. At a global scale, the 10 and 40-year average eruptive rates calculated from 1980 to 2019 have the same magnitude as the long-term average eruptive rates (from thousand to millions of years), because in both cases rates are scaled for times comparable to the recurrence time of the biggest eruptions occurred.

1980 年至 2019 年陆上火山活动的时空量化：固体产物、质量和平均喷发率

火山活动是在地球内部和地球表面之间传递质量和能量的主要机制之一。然而，熔岩、火山灰和爆炸性火山碎屑沉积物的全球质量通量没有得到很好的约束。在这里，我们回顾了一份全球汇编对 1980 年至 2019 年喷发产物质量的已发表估计。我们从史密森尼全球火山计划数据库中确定了 1980 年至 2019 年间发生的 1,064 次岩浆喷发。对于每次喷发，我们都报告了总喷发量及其在不同火山产物中的分布情况。使用该数据集，我们在全球和区域范围内量化了 1980 年至 2019 年陆上火山活动及其产物的时空演变。在每个分析的十年中喷发的岩浆质量范围为 1.1-4.9 × 10¹³ 公斤。熔岩是主要的陆上喷发产物，约占岩浆喷发总量的 57%。与最大喷发（震级≥6）相关的产物，重现时间长，可以暂时使爆炸产物比熔岩更丰富（例如，十年1990-1999）。23 座火山产生了约 72% 的总质量，而两组不同的 15 座火山喷发了超过 70% 的喷出或爆炸产物的总质量。在全球范围内，从 1980 年到 2019 年计算的 10 年和 40 年平均喷发率与长期平均喷发率（从千年到数百万年）具有相同的幅度，因为在这两种情况下，喷发率都是按可比较的时间缩放的到最大喷发发生的复发时间。
