Here's why:

* Stratovolcanoes are also known as composite volcanoes.

* They are characterized by their steep conical shape formed by layers (strata) of solidified lava flows, tephra (ash), and volcanic debris.

* They are known for their explosive eruptions, which can be incredibly destructive.

Mount Pinatubo's 1991 eruption was one of the most powerful volcanic eruptions of the 20th century. It released a massive amount of ash and debris, significantly altering the surrounding landscape.
