Welcome to the first of its kind, the Geotandem 01! A collaborative series between EGU divisions. Interdisciplinarity is intrinsic to Geosciences, so we want to showcase how researchers approach the same topics from different but also complementing perspectives. In each edition, we will bring you a high-interest topic for the community seen from the eyes of diverse disciplines. Today, the Tectonic ...[Read More]

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]

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]
