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]

Effects of decelerating India-Eurasia convergence on the crustal flow and topographic evolution of the Tibetan Plateau

Arnab Roy and edited by Giridas Maiti October 12, 2022

The Tibetan Plateau is the most extensive elevated surface on the Earth, stretching ~1,000 km north to south and 3,200 km east to west, with a mean elevation of greater than 4.5 km and located north of the Indian subcontinent. The formation of this Plateau has profoundly influenced the variations and evolution of Asian climate, strengthening of the South-Asian Monsoon, development of the large Asi ...[Read More]

X and mantle plumes: the deep quest

Martina Monaco and edited by Arushi Saxena October 5, 2022

Seismic discontinuities necessitates mechanisms that would generate them and therefore, help us better understand the internal structure of the Earth. This week, Martina Monaco talks about the mysterious X-discontinuity — observed under several hotspots at upper mantle depths of ~ 290 km —and how it relates to the rising plumes. According to the Oxford Dictionary, only 400 words in the English la ...[Read More]
