Here's why this is important:

* Basaltic andesite is a type of magma that is intermediate in composition between basalt and andesite. It is relatively viscous (thick) compared to basalt, which leads to explosive eruptions.

* Explosive eruptions: The thick magma traps gases, causing pressure to build up. When the pressure is released, it leads to powerful explosions that send ash and rock high into the atmosphere. This is what happened during the 2010 eruption of Eyjafjallajökull, disrupting air travel across Europe.
