Lahars on Atlasov Island in September-October 2022 (Kuril Islands)

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The article provides information about nival-volcanogenic, possibly glacial-volcanogenic, mudflows (lahars) on three streams on the south side of Atlasov Island (Kuril Islands, Russia). The island is an active stratovolcano Alaid, 2339 m asl high.

Subduction Initiation of the Southern Branch of the Paleo‐Asian Ocean in the Middle Ordovician in the Southern Beishan Orogen

Earth and Space Science, Volume 10, Issue 3, March 2023., 2023
Abstract The subduction initiation and the early‐stage tectonics of the southern Paleo‐Asian Ocean have rarely been discussed. To address these problems, we report new geochemical and geochronological data of arc‐related volcanic rocks in the Huaniushan arc of the southern Beishan.

To the 90th anniversary of the eruption of the Taketomi side volcano (Atlasov Island, Kuril Island Arc)

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2023
The eruption of the unique Taketomi side volcano, located on Atlasov Islandin the northern part of the Kuril island arc, started underwater and ended on land. It happened before people’s eyes and was essentially the formation of a new volcano.

Changes in Abiotic Drivers of Green Sea Urchin Demographics following the Loss of a Keystone Predator

Journal of Marine Sciences, Volume 2023, Issue 1, 2023., 2023
Sea urchin population demographics can respond to changes in keystone species abundances, with the magnitude of these responses varying depending on environmental influences. In this study, sea urchin populations were surveyed across 15 Aleutian archipelago islands over a 30‐year period to understand how patterns of sea urchin demography (density ...

Correlations Between Subduction of Linear Oceanic Features and Arc Volcanism Volume Around the Pacific Basin

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 12, December 2022., 2022
Abstract Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along‐arc spatial distributions. In this study, we address a fundamental question, namely, how do subduction zones and volcanic arcs respond to the subduction of “atypical” oceanic lithosphere.
