How does the Olympus Mons erupt does it spray explode?

Answer 1

Olympus Mons, the largest volcano in the solar system, primarily erupts through effusive eruptions rather than explosive ones. This means that lava flows out gently, creating broad, shield-like structures rather than violent explosions that spray ash and gas. The low viscosity of the basaltic lava allows it to travel long distances, resulting in the extensive lava plains characteristic of Olympus Mons. While there may be occasional explosive activity, it is not the dominant form of eruption for this massive volcano.
