Strombolian eruptions, wherein lava fountaining and lava effusion can be observed, are minor eruptions compared with explosive Vulcanian, Pelean and Plinian eruptions.
By analyzing the geological layers of past eruptions, the scientists have concluded that Popocatepetl either emits river-like floods of ash or undergoes a Plinian eruption every 1,650 years.
Plinian eruptions thrust massive volumes of aerosols into the atmosphere, blocking the sunlight Earth absorbs and resulting in a widespread cooling effect.
The study also confirmed the influence of Plinian eruptions on temperatures, as the tremendous amount of aerosols emitted into the atmosphere by an eruption blocked incoming solar radiation and led to a cooling trend in areas subjected to the strongest volcanic forcing, especially over land.
