Lava is not explosive. Eruptions of magma from a volcano can be explosive or not, depending on the pressure pushing it up from deep below the Earth's surface and on how hot (thin) it is.

Lava can be explosive if it is high in gas content, such as dissolved water vapor or carbon dioxide, which can cause pressure to build up and lead to explosive eruptions. On the other hand, lava can be non-explosive if it is low in gas content and flows more easily without building up pressure, resulting in effusive eruptions with slower lava flows.
