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.
The current eruption of Kilauea on Hawai'is big island can tell us a lot about what is going on beneath the volcano and may provide lessons for future eruptions.
At Kīlauea in Hawai'i, a recent volcanic eruption has created some of the most spectacular sights in nature. But also danger for those around it.
Fountains of lava from Hawaii's Kilauea volcano are dramatic, but the most deadly impacts of volcanic eruptions are toxic gases and ash and mud flows.
How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.
