Noise produces volcanic seismicity, akin to a drumbeat
Volcanoes are chaotic systems. They are difficult to model because the geophysical and chemical parameters in volcanic eruptions exhibit high levels of uncertainty. Scientists from the Ural Federal University in Ekaterinburg have further extended an eruption model to the friction force at work between the volcanic plug and volcanic conduit surface. The results, published in EPJ B, provide evidence that volcanic activity can be induced by external noises that would not otherwise have been predicted by the model. (2015-05-11)

Volcanic activity may have contributed to Cretaceous extinction

(2010-01-19)

A new tool to predict volcanic eruptions
Earth's atmosphere is made up of 78% nitrogen and 21% oxygen, a mixture that is unique in the solar system. But where did the nitrogen come from? Did it escape from Earth's mantle through volcanic activity? To try to answer these questions, CNRS researcher Jabrane Labidi and his colleagues collected samples of gas from several volcanic sites. Their highly precise data could help to predict future volcanic eruptions. (2020-04-15)

New magma pathways after giant lateral volcano collapses
Giant lateral collapses are huge landslides occurring at the flanks of a volcano. Such collapses are rather common events during the evolution of a large volcanic edifice, often with dramatic consequences such as tsunami and volcano explosions. These catastrophic events interact with the magmatic activity of the volcano, as a new research by scientists of GFZ German Research Centre for Geosciences in Nature Communications suggests. (2017-10-23)
