A mysterious cone has developed due to unusual volcanic activity on Hawaii.
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.
Fuego and other volcanoes are considered sacred in the Maya culture, but forced Spanish colonisers to move their new capital city.
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 Kīlauea volcano on Hawai'i's big island is threatening to produce violent and energetic eruptions not seen since 1924.
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.
East Africa Rift is undergoing a process that will see the Horn of Africa split from the rest of the continent.
The short answer is that while lava is hot, it's not hot enough to melt the rocks that make up the side of the volcano.
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.
A new study has found a way to predict eruptions at Mount Etna within two weeks.
We asked three volcanologists what to look out for in the year ahead.
Robots, like drones, are filtering the natural world through algorithms and turning the world into data.
And will the aviation sector implement vital lessons learned from Icelandic disruption in 2010?
Stand by for drones, robots and sensors to the rescue.
Until late November, Bali's high economic dependence on tourism led its Tourism Board to dismiss the dangers of the Mount Agung volcano. This severely undermined the reputation of destination Bali..
'Volcano forensics' involves a mixture of modern day monitoring and analysis of past eruptions. Geologists use volcanic rocks as a kind of time capsule to assess what happened previously.
