Definitions:

Gas Flux

The rate of gas transfer from one phase or place to another, often measured in environmental and geological studies.

Explosive

Characterized by a sudden and forceful release of energy, often with the generation of high temperatures and the release of gases.

Nonexplosive

Characterizing volcanic eruptions or events that release magma, gas, and ash in a relatively gentle and steady manner.

Thin Lava Flows

Layers of lava that spread out over large areas and cool to form relatively thin sheets of rock.
