1 Two years into its life, pyroclastic activity began to wane, and the outpouring of lava from its base became its primary mode of activity. 2  Eruptions ceased in 1952, and the final height was 424 m (1,391 ft). 3  This was the first time that scientists are able to observe the complete life cycle of a volcano.here are two types of eruptions in terms of activity, explosive eruptions and effusive eruptions. Explosive eruptions are characterized by gas-driven explosions that propels magma and tephra. Effusive eruptions, meanwhile, are characterized by the outpouring of lava without significant explosive eruption.
