The material from Pinatubo is intermediate to felsic in composition, which would form a rock called dacite. Eruptions from Pinatubo tend to produce ash and pumice rather than lava.
what causes a eruption to be liolent is the type of lava -felsic lava is non-violent -mafic lava is violent
No. Pinatubo tends to produce ash and pumice rather than lava flows. A'a is a textural variety of basaltic lava. Pinatubo in recent history has erupted dacitic material, which is far more viscous.
Analysis of deposits suggets that many of Pinatubo's eruptions are similar to the one that occurred in 1991. This eruption produced enormous clouds of ash and pumice.
No. The 1991 eruption of Mount Pinatubo was a highly explosive Plinian eruption. Instead of lava flows it produced a massive column of ash and pyroclastic flows.
Mt Pinatubo is a composite volcano and the lava is primarily dacitic making it explosive and highly viscous. Dacite would likely erupt at about 800 degrees Celsius.

Mount Pinatubo erupt violently, but does not produce lava flows. It creates massive clouds of ash and pumice.
They both depend on eruptions for their formation but lava tubes form only in large flows of low-viscosity, basaltic,lava. I don't know if this applies to Mt. Pinatubo.

tumalon or jump in mt. Pinatubo to experience it but i jump in mt. Pinatubo and it was so so cool inside many lava and fireballs
Mount Pinatubo primarily erupts dacitic magma.
yes Mt Pinatubo is a composite volcano
Mount Pinatubo had LATERAL eruption. It means, generally volcano erupts at its highest peak where its vent finds an opening, but mount Pinatubo got a weak side and therefore it erupted laterally.
Mount Pinatubo is a Stratovolcano or also known as Composite Volcano
