A mysterious cone has developed due to unusual volcanic activity on Hawaii.
Lifeguards and volunteers run across an ash covered slope after the June 3 eruption of the Fuego volcano in Guatemala.
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.

The Kīlauea volcano on Hawai'i's big island is threatening to produce violent and energetic eruptions not seen since 1924.
Although it is very hot, when lava flows over the ground, it generally does not melt the soil or rock.

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.
A new study has found a way to predict eruptions at Mount Etna within two weeks.

'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.

How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.
Volcanologists often visit active volcanoes in order to observe eruptions and collect samples of lava and ash.
Volcanologists study the formation and eruptions of volcanoes - surely one of the most interesting jobs around. However, it can also be very dangerous.

What can we expect Australia's next volcanic eruption to be like? That depends where and when it happens, and it could be sooner than you think.
Scientists have found a way to narrow down the best signs that a specific volcano is about to blow.

Mount Ontake, Japan’s second-highest volcano, erupted killing at least 31 people on September 27. Since then, there has been feverish speculation about why tourists were on an active volcano and why the…
The impressive scar-like rifts of the aptly-named Afar region.
In September 2014, the Natural Environment Research Council will launch a major five-year programme to study the volcanoes of Ethiopia’s Great Rift Valley. The project team contains core investigators…
The explosive eruption of Sarychev Volcano, on Russia’s Kuril Islands, northeast of Japan, seen from the International Space Station.
You can learn a lot about volcanoes by studying explosions. The more we can learn about their explosive behaviour, the more chance we have of saving lives when they suddenly erupt. There are many volcanoes…
The huge caldera of Mount Tambora, Indonesia – still active today.
Most have heard of the Battle of Waterloo, but who has heard of the volcano called Tambora? No school textbook I’ve seen mentions that only two months before Napoleon’s final defeat in Belgium on June…
