Deep-sea volcanoes don't just produce lava flows, they also explode!
— 29 Mar 2011 16:19 | Geology and palaeontologyBetween 75 and 80 per cent of all volcanic activity on Earth takes place at deep-sea, mid-ocean ridges. Most of these volcanoes produce effusive lava flows rather than explosive eruptions,…
Oscillating 'plug' of magma causes tremors that forecast volcanic eruptions: UBC research
— 24 Feb 2011 18:47 | Geology and palaeontologyUniversity of British Columbia geophysicists are offering a new explanation for seismic tremors accompanying volcanic eruptions that could advance forecasting of explosive eruptions…

— 18 Nov 2010 10:18 | Geology and palaeontologyMonths of volcanic restlessness preceded the eruptions this spring of Icelandic volcano Eyjafjallajoekull, providing insight into what roused it from centuries of slumber…
Novel ocean-crust mechanism could affect world's carbon budget
— 16 Nov 2010 12:27 | EnvironmentThe Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. The process is critical to the planet's metabolism,…
Mars volcanic deposit tells of warm and wet environment
— 31 Oct 2010 18:16 | AstronomyRoughly 3.5 billion years ago, the first epoch on Mars ended. The climate on the red planet then shifted dramatically from a relatively warm, wet period to one that was arid and cold.…
The hot atmosphere of Venus might cool the interior of Earth's sister planet
— 21 Sep 2010 12:49 | AstronomyThe heat in the atmosphere of Venus, induced from a strong greenhouse warming, might actually have a cooling effect on the planet's interior. This counter-intuitive theory is based…
