From the very early years on this Planet, earthquakes have always captivated people’s attention. The feeling of admiration and fear always lies within us, especially drawing on the most recent megathrust earthquake that hit the south coast of Kamchatka’s Peninsula, in Russia, twice this year. Therefore, in this week’s blog, we aim to explore how this phenomenon evolved and why this specific region ...[Read More]

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

Changyeol Lee and edited by Giridas Maiti January 11, 2023

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]
