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.
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.
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.
The remote Pilbara region of Western Australian formed many billions of years ago when the Earth was much hotter and the crust softer than it is today.
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.
Volcanologists study the formation and eruptions of volcanoes - surely one of the most interesting jobs around. However, it can also be very dangerous.
The planet is more similar to Earth than any other – except when it comes to supporting life.
In Iceland, an audacious project to tap into magma deep below the surface may usher in a new era of geothermal power.
Scientists have found a way to narrow down the best signs that a specific volcano is about to blow.
Around 60 volcanoes erupt in the average year. On any particular day, there are usually about 20 volcanoes erupting somewhere in the world. Naturally, they can’t all make headlines. But when there are…
The Bárðarbunga (or Bardarbunga) volcano has erupted, evoking memories of the 2010 Icelandic ash cloud that caused chaos across European and North American air routes. Dave McGarvie, a volcanologist at…
