Shield volcanoes produce fast flowing lava. They erupt frequently, but eruptions are gentle because the lava is so thin and does not trap gas in the volcano.
Pahoehoe and AA lava are produced by quiet eruptions. This means that instead of a blast or explosion, the lava just flows out of the volcano. Pahoehoe lava is hot and flows quickly. AA lava is cooler in temperature and doesn't flow as quickly.
During a nonexplosive eruption, lava flows out from the volcano in a slow and steady manner. The lava is typically less viscous, allowing it to flow smoothly and cover greater distances. This type of eruption is characterized by the slow-moving streams of lava that can create new land formations as they cool and solidify.
A quiet eruption typically produces basaltic lava. This type of lava is low in viscosity and flows easily, resulting in gentle, slow-moving lava flows. It often forms shield volcanoes with broad and gently sloping sides.
A river of lava is called a lava flow. It is a mass of flowing molten rock that moves downhill from a volcano during an eruption.
Lava is produced after the eruption and flows from the bottom of a shield volcano. Shield volcanoes have broad, gentle slopes and are primarily built up by the flow of low-viscosity basaltic lava, which can travel long distances. This type of volcano typically has non-explosive eruptions, allowing lava to flow freely from the summit and fissures. Examples include Mauna Loa in Hawaii and Kilauea.
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.

No. A lava flow usually indicates an eruption that is not explosive.

The type of eruption that a composite volcano has is lava flow with cinders and bombs in an explosive eruption
The 1980 eruption of Mount St. Helens did not produce any lava flows. That eruption produced massive clouds of ash and pumice. Later activity formed a lava dome, but not lava flows. No eruption that has been directly observed at Mount St. Helens has produced lava flows, but some prehistoric eruptions have.
