Generally yes. A'a and pahoehoe are both varieties of basaltic lava, which usually erupts fairly quietly.

When does a volcano erupt quietly?
If it has liquid Lava
Why do some volcanoes erupt while others erupt quietly?
This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.
Does mt Pinatubo's lava flow violently or quietly?
Mount Pinatubo erupt violently, but does not produce lava flows. It creates massive clouds of ash and pumice.
Do volcanoes erupt mainly due to the buildup of water vapor and carbon dioxide?
Volcanoes supplied by subduction zones usually erupt due to buildup of pressure of these gases. This lava tends to erupt explosively as solid pieces of ash, cinders, bombs, etc. often filled with gas bubbles. Volcanoes supplied by deep mantle hotspots have almost no gas in their lava and erupt due to buildup of magma rising from the hotspot. This lava tends to erupt quietly as a fluid.
Can a stratovolcano erupt blocky lava?
Yes. Stratovolcanoes can erupt blocky lava flows, basaltic lava flows, or may erupt explosively.
What type of lava comes from what volcano?
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
When volcano erupt they expel what zircons or lava?
lava
What causes the quiet erupt and loud erupt?
Loud Erupt: The magma is really thick It is cooler lava More silicia Quiet Erupt: Thin Hotter lava low silica
What happens to lava when a volcano erupt?
lava shoots out of the top
What do they do when the erupt?
its explodes and lava comes out
Can lava erupt from fissures?
yes
