Linking Magma Storage and Ascent to Eruption Volume and Composition at an Arc Caldera

open access: yesGeophysical Research Letters, 2020
Conceptual models of magma storage and transport under calderas favor a connected system of sills and dikes. These features are individually below the resolution of standard seismic tomography, but radial seismic anisotropy can reveal where they exist in

Meydan Kalderası ve Gürgürbaba Domu Çevresinin Jeomorfolojik Özellikleri

open access: yesCoğrafi Bilimler Dergisi, 2019
The aim of this study is to investigate the geomorphological characteristics of Meydan Volcanic area located in the Van province north of Lake Van. Factors such as tectonic volcanic, hydrographic, which are effective in the geomorphological evolution of ...

The Internal Structural Evolution of Calderas: Results from 3D Discrete Element Simulations

open access: yesGeosciences, 2019
The structural evolution of calderas is a key issue in volcanology and has profound implications for hazard analysis and the exploitation of geothermal energy and hydrothermal ores.

Understanding the link between circumferential dikes and eruptive fissures around calderas based on numerical and analog models

open access: yesGeophysical Research Letters, 2016
Active calderas are seldom associated with circumferential eruptive fissures, but eroded magmatic complexes reveal widespread circumferential dikes. This suggests that, while the conditions to emplace circumferential dikes are easily met, mechanisms must

Structural model of the Northern Latium volcanic area constrained by MT, gravity and aeromagnetic data

open access: yesAnnals of Geophysics, 1997
The results of about 120 magnetotelluric soundings carried out in the Vulsini, Vico and Sabatini volcanic areas were modeled along with Bouguer and aeromagnetic anomalies to reconstruct a model of the structure of the shallow (less than 5 km of depth ...

Geology and evolution of the Late Pleistocene-Holocene La Primavera caldera complex, western Trans-Mexican Volcanic Belt

open access: yesJournal of Maps
La Primavera caldera is located in the western part of the Trans-Mexican Volcanic Belt. The landscape is represented by caldera-rim, intra-caldera, and extra-caldera domes and volcanoes associated with pyroclastic, lacustrine, and volcaniclastic deposits,

Early successional changes in coniferous forest small mammal communities following a high‐severity summer wildfire

open access: yesEcosphere
Forest fires in the southern Rocky Mountains are changing due to climate warming and increased fuel loads. Landscape‐scale stand‐replacement fires create extensive treeless swaths without regenerative seed sources, leading to long‐term conversion of ...

Identification and persistence mechanism of very small glaciers and perennial snow patches in the northern Japanese Alps

open access: yesFrontiers in Earth Science
In this study, we measure ice thickness and flow and reveal that Shakushizawa and Kaerazuzawa perennial snow patches (PSPs) in the northern Japanese Alps are glaciers instead. Due to their size, they are very small glaciers (VSGs).

AI‐Enabled Circular Business Model Transition for Mitigating Climate Change: A Natural Resource‐Based View Perspective on Business Strategies

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The role of artificial intelligence (AI) in achieving sustainability goals has garnered attention in academic literature. While AI has been argued to be crucial in addressing circularity challenges, organizations face challenges in configuring a business model.

The Evolution of Galápagos Volcanoes: An Alternative Perspective

open access: yesFrontiers in Earth Science, 2018
The older eastern Galápagos are different in almost every way from the historically active western Galápagos volcanoes. Geochemical, geologic, and geophysical data support the hypothesis that the differences are not evolutionary, but rather the eastern ...
