What is the material being extruded by Mount Mayon? Where do you think did this material come from?

The material being extruded by Mount Mayon is "Lava".

Throughout view of such increasingly prevalent eruption occurrences, the water level of the wells drilled in nearby crater Mount Mayon, this same present volcano together in dynamic condition, is beginning to decrease.The episodes have been characterized by a resilient oozing but also welling of lava, frantic ejection of blocks as large as vehicles, and angered release of thick ashes and sedimentary sprinkles up to a few 100 kilometers over the crater lip.
