Direct Detection of Active Volcanism on Venus
Venus is called Earth’s twin because these two planets have comparable masses and diameters. However, our understanding of Venus is limited due to the thick atmosphere shrouding its surface. We […]

Phosphine on Venus: Volcanism as an Abiotic Source?
The surface of Venus is inhospitable to life as we know it, but the planet’s thick clouds have been hypothesized to be a potentially habitable environment for Earth-like lifeforms. While […]
Early Martian Supereruptions in Arabia Terra
Volcanism is a fundamental geologic process on the terrestrial planets, including Mars. It has been suggested that several large, circular depressions in the northern region of Mars called Arabia Terra […]
Young Volcanism on Venus: An Exploration Opportunity
Venus is a volcanological wonderland that has some of the largest volcanoes in the solar system. However, there are many unanswered questions and numerous debates about these volcanoes, including what […]
Ferrovolcanism: When Metal Worlds Erupt
Volcanic eruptions can reshape and chemically alter planetary surfaces, as well as provide important clues to the compositions of planetary interiors. The most common type of volcanic eruptions on Earth […]
Layered Features Hint at the Origin of Tesserae on Venus
The tesserae of Venus are some of its oldest and most tectonically deformed regions. Standing at high elevations compared to the volcanic plains that dominate the planet, their morphology, gravity […]
Asteroid Impacts, Volcanism, and the Extinction of the Dinosaurs
The mass extinction event 66 million years ago between the Cretaceous and Paleogene periods decimated non-avian dinosaurs, although the primary cause of this extinction has been intensely debated. There was […]
The Coronae of Venus: Evidence for Ongoing Volcanic Activity?
So far, the Earth is the only known planet to experience globally active plate tectonics and active volcanism; however, more evidence is emerging that Venus may have also experienced recent […]
Lava-like Flows on Mars May be Mud
To date, it has been difficult to determine whether volcanic structures on Mars are necessarily lava flows. A new study suggests that these features were formed from the movement of […]
Part of Mars’ Largest Volcano Might Have Floated Away on an Early Sea
The Medusae Fossae Formation, found on Mars’ equator, is a large geologic unit whose origin has remained mysterious. It appears to be composed of volcanic materials, but has no obvious […]
Recent Volcanic Activity on Venus
Lava flows on the surface of Venus are suggested to be only a few years old according to a study of how the mineral olivine is altered by the Venusian […]
Volcanic Eruption of Molten Iron on Asteroids
An upcoming NASA space mission to the asteroid 16 Psyche will allow us to examine rare metallic asteroids in the solar system. Unlike most asteroids, Psyche appears to be composed […]

Asia Oceania Geosciences Conference 2018 June 3-8, Honolulu, Hawaii Abstract submission deadline: January 19, 2018 http://www.asiaoceania.org/aogs2018/public.asp?page=home.htm The surfaces of the terrestrial planets and their satellites have been largely shaped through volcanic […]
Boundary-related Impact Cratering and Volcanism at GSA Annual Meeting: Abstract Deadline Aug. 1
Boundary-related Impact Cratering and Volcanism, topical session, at the GSA Annual Meeting, Seattle, October 22-25, 2017. August 1 Abstract Deadline Approaching Emerging work is causing new debate about the role […]
Proposal of New Book on Martian Volcanism
Dear colleagues, I’m putting together a proposal for a new specific book on Martian volcanism. I think that time has come for such a book, particularly after the latest discoveries (i.e. volcanic […]
VOLCANISM, PLATE TECTONICS, HYDROTHERMAL VENTS AND LIFE

Angra do Heroismo, Azores, Portugal, 23 August – 1 September 2016 The course aims to give participants a thorough introduction into influence of volcanism, plate tectonics on life and the […]
AGU SESSION 7445 – VOLCANISM AND TECTONISM ACROSS THE SOLAR SYSTEM
There will be a session on planetary volcanism and tectonism at this year’s AGU Fall Meeting, 14-18 December. Please consider submitting an abstract for this session. Further details are provided below. The […]
NASA Mission Points to Origin of ‘Ocean of Storms’ on Earth’s Moon
Using data from NASA’s Gravity Recovery and Interior Laboratory (GRAIL), mission scientists have solved a lunar mystery almost as old as the Moon itself. Early theories suggested the craggy outline […]
A Hellacious Two Weeks on Jupiter’s Moon Io
Three massive volcanic eruptions occurred on Jupiter’s moon Io within a two-week period in August of last year. This led astronomers to speculate that such “outbursts,” which can send material […]
