Volcanism of the South Aegean Volcanic Arc [PDF]

open access: yesElements, 2019
Volcanism along the South Aegean volcanic arc began about 4.7 Ma and has lasted until the present day, with eruptions at Methana, Milos, Santorini, Kolumbo and Nisyros volcanoes in historical times. These volcanoes can be grouped into five volcanic fields: three western fields of small, mostly monogenetic edifices, and two central/eastern fields with ...

Features That Favor the Prediction of the Emplacement Location of Maar Volcanoes: A Case Study in the Central Andes, Northern Chile

open access: yesGeosciences, 2020
Maar volcanoes are monogenetic landforms whose craters cut below the pre-eruptive surface and are surrounded by a tephra ring. Both the maar crater and the surrounding tephra rim deposits are typically formed due to magma–water explosive interactions ...

Geochemical sourcing of volcanic materials imported into Teti'aroa Atoll shows multiple long‐distance interactions in the Windward Society Islands, French Polynesia

open access: yesArchaeology in Oceania, Volume 54, Issue 3, Page 184-199, October 2019., 2019
Teti'aroa, located 28 nautical miles (52 km) north of Tahiti, lies at the periphery of the Windward Society islands. At the end of the eighteenth century, this atoll was presumably controlled by the chiefdom of Porionu'u, which included the districts of Pare and Arue on the north coast of Tahiti.

Tectonics and Sliver Motion in Costa Rica: Strain Partitioning Constrained by GNSS Velocities Data

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The tectonic deformation of Costa Rica is controlled by the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate along the Middle America Trench, with oblique convergence in northern Costa Rica to 2024 from 154 permanent stations distributed across Costa Rica to derive for the first time spatially continuous ...

Extract from Bougainvillea xbuttiana (Variety Orange) Inhibits Production of LPS‐Induced Inflammatory Mediators in Macrophages and Exerts a Protective Effect In Vivo

open access: yesBioMed Research International, Volume 2019, Issue 1, 2019., 2019
Background. Different pharmacological properties, such as antioxidant, antiproliferative, and anti‐inflammatory properties, have been described among natural products. We previously described that the Bougainvillea xbuttiana (Variety Orange) ethanolic extract (BxbO) has an anti‐inflammatory effect; however, this action is not fully understood.
