Single-Station Seismo-Acoustic Monitoring of Nyiragongo's Lava Lake Activity (D.R. Congo)

open access: yesFrontiers in Earth Science, 2018
Since its last effusive eruption in 2002, Nyiragongo has been an open-vent volcano characterized by the world's largest persistent lava lake. This lava lake provides a unique opportunity to detect pressure change in the magmatic system by analyzing its ...

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

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along‐arc spatial distributions.

The 2001 Taupō Fault Belt Seismicity as Evidence of Magma‐Tectonic Interaction at Taupō Volcano

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The Taupō Volcanic Zone (TVZ) is the southern extent of the Tonga‐Kermadec volcanic arc and encompasses the Taupō Rift, with the two structures accommodating extension through the central North Island of New Zealand via magmatic and tectonic processes,

High precision locations of long-period events at La Fossa Crater (Vulcano Island, Italy)

open access: yesAnnals of Geophysics, 2009
Since the last eruption in 1888-90, the volcanic activity on Vulcano Island (Aeolian Archipelago, Italy) has been limited to fumarolic degassing. Fumaroles are mainly concentred at the active cone of La Fossa in the northern sector of the island and are ...

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

open access: yesGeological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Use of Local Seismic Network in Analysis of Volcano-Tectonic (VT) Events Preceding the 2017 Agung Volcano Eruption (Bali, Indonesia)

open access: yesFrontiers in Earth Science, 2021
This study provides an attempt to analyze the pre-eruptive seismicity events for volcano eruption forecasting. After more than 50 years of slumber, Agung volcano on Bali Island erupted explosively, starting on November 21, 2017. The eruption was preceded

Tectono‐Sedimentary Evolution of the Neogene İnegöl Basin (NW Anatolia): Constraints on Transtensional Basin Development at the Junction of the Western Anatolian Extensional Province and the North Anatolian Fault Zone

open access: yesGeological Journal, EarlyView.
The study outlines the tectono‐sedimentary evolution of the İnegöl Basin in north‐western Anatolia. Basin formation was controlled by interacting extensional and strike‐slip fault systems linked to uplift of the Uludağ Massif. Terrestrial sedimentation from the Miocene to Pleistocene is reconstructed using abundant fossil mammal assemblages that ...
