Water and gas geochemistry of springs in Ulleungdo volcano, South Korea: Implications for degassing of upper mantle-derived volatiles in Northeast Asia

Ulleungdo, a volcanic island located in the back-arc basin (East Sea/Sea of Japan) of the Japanese arc, is one of the Cenozoic intraplate volcanoes in Northeast (NE) Asia. Due to the unique tectonic characteristics of the transition from the past back-arc opening phase to the current intraplate setting, elucidating the magma origin of this volcano […]

Precise Relocation and Source Characterization of Two Earthquake Sequences in Yellow Sea Using Regional Lg-Wave Observations

Abstract:  Two significant earthquakes of magnitude ML 4.6 and 4.5 occurred on 18 January and 3 December 2021 in the central region of the Yellow Sea, respectively. The earthquakes occurred beneath the Gunsan sedimentary basin at about 10 km depth with a strike‐slip faulting mechanism on nodal planes striking northwest–southeast (NW–SE) and north‐northeast–south‐southwest (NNE–SSW). Despite a lack of […]
