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.

Guatemala has ended its Fuego volcano rescue mission and declared 110 dead. But people in the hot, ash-covered eruption zone say that the real death tally is much higher and that they’ll keep digging.

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.
Pyroclastic flows are biggest danger in these eruptions.

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.
It feels as if volcanoes in our region are going off at a high rate right now - but it’s reasonably normal activity for the “Ring of Fire” belt running around the Asia Pacific.

Research suggests a new threat to life on Earth from the meteorite’s crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet’s history.
Stand by for drones, robots and sensors to the rescue.
