Our neighbouring planet Venus is gaining popularity in the terrestrial planetary sciences, especially since the selection of three new Venus missions by NASA and ESA in 2021. Now, for the first time ever, scientists have directly observed surface changes that indicate active volcanism on Venus. This discovery was made with data from NASA’s 30-year-old Magellan mission and is only a small preview f ...[Read More]

Planetary Boundaries: A Framework against Geodynamics?

Planetary Boundaries: A Framework against Geodynamics?
The risks of crossing the Planetary boundaries for our planet Earth illustrated by Prachi Kar.

How can we determine a ‘safe operating space’ for humanity? In this week’s blog, Professor Ilan Kelman from University College London shares his thoughts about Planetary boundaries, and whether this framework will be successful for the next generations to come.  The planetary boundaries framework (Rockström et al. 2009ab; Steffen et al. 2015) might be useful for communicating some of humanity’s im ...[Read More]

Arc and Intraplate Volcanism in Northeast Asia Since mid-Miocene: Numerical model studies

Arc and Intraplate Volcanism in Northeast Asia Since mid-Miocene: Numerical model studies
Locations of the Quaternary arc and intraplate volcanoes in Northeast Asia, depicted as black triangles, with major plate boundaries. Modified from Kim et al. (2015).

Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China have occurred abo ...[Read More]
