Abstract A pyroclastic density current (PDC) was observed with the phreatomagmatic eruption of the Kuchinoerabujima volcano, southern Japan, on May 29, 2015. The PDC flowed down in all direction from the source crater, forming three major branches. T

Detecting transitions between different eruption styles through real-time monitoring can mitigate the risk posed by volcanic hazards. During periods of eruptive activity, changes in ash characteristics can reflect changes in magma behavior in the con

Cenozoic intraplate volcanism in northern and northeastern Hokkaido appears to have been closely associated with the Late Oligocene to Mid-Miocene opening of the Japan and Okhotsk Seas (c. 23–12 Ma). Between 12 and 2 Ma, volcanism appeared in the M

We present geochemical, Sr, Nd and Pb isotopic data for the youngest back-arc tholeiitic and alkali basalts in the southern tip of Goto Islands along the Taiwan–Shinji Folded Belt in northwestern Kyushu, SW Japan. The data are compared with those m

Despite the existence of a growing database of the amount of H 2 O in melt inclusions, it is difficult to calculate the bulk H 2 O content for vapor-saturated magma because the observable H 2 O concentration in melt is limited by its solubility. To o

Samples of Kurile arc lavas erupted between 1.6 Ma and ca. 30,000 years were collected from the Kutcharo, Mashu and Akan caldera area in NE Hokkaido, about 150 km west of the Kurile trench. The samples include rhyolitic pumice, rhyolite, dacite, ande

Geochemical and isotopic data are reported for 20 Ma high-magnesian andesite (HMA) lavas erupted on the forearc side of Central Japan in the Choshi coastal area (Chiba). Rarely olivine-phyric ( 345 ppm), high Sr (> 520 ppm), high Sr/Y (ca. 30), and h
