Would an eruption in Melbourne really match Hawaii’s volcanoes? Here’s the evidence

Melbourne lies at the eastern end of a volcanic province, but when’s it going to blow? Understanding the geology of Melbourne and comparing it to Hawaii is really helpful in calculating risk.

Curious Kids: Why do volcanoes erupt?

When magma rises towards the surface gas bubbles start to form. Whether or not they can escape as the magma is rising affects how explosive the eruption will be.

From Kilauea to Fuego: three things you should know about volcano risk

Important points about volcanoes: location matters, explosiveness can be predicted to an extent, and fast-moving flows of volcanic materials (known as pyroclastic flows) are deadly.
