No. Ash forms when gas-rich magma is blown into fine droplets during explosive eruptions, quickly cooling to form tiny particles of glass.
Layers of thin runny lava that flow over a wide area before they cool and harden can build up lava plateaus or volcanic fields.
silica content
it wil have thin lava because the lava is "runny" and shield volcanoes are made from nonexplosive eruptions so they will be quiet when they erupt.
An eruption with thin, runny magma containing very little silica is called an effusive eruption. This type of eruption usually results in lava flows that can travel long distances from the volcano.
The wide and flat land form that repeated flows of lava form is called a lava plateau. Lava plateaus are created by successive eruptions of low-viscosity lava that spreads out in thin layers, building up over time to create a broad, flat area.

Pahoehoe and aa
first lava flows out of several long cracks in an area. the thin runny lava travels far before cooling and solidifying. again and again floods of lava flow on top of earlier floods. After millions of years these layers of lava can form high plateaus!

"Runny" typically refers to a substance that has a thin or watery consistency, such as a runny nose or runny egg yolk. It can also describe something that is leaking or flowing uncontrollably.
the Philippines volcano's form thin layer of cooled lava but not really cold like freezing
A+ answer : shield volcano
