Deep magma storage during the 2021 La Palma eruption. [PDF]
Sci Adv, 2023 The 2021 La Palma eruption provided an unpreceded opportunity to test the relationship between earthquake hypocenters and the location of magma reservoirs. We performed density measurements on CO 2 -rich fluid inclusions (FIs) hosted in olivine crystals that are highly sensitive to pressure via calibrated Raman ...

Hydrothermal Cooling as a Requirement for Short Storage of Silicic Magmas
Geochemistry, Geophysics, Geosystems, 2021 Large (>50 km3) magma bodies that contribute to caldera‐forming eruptions in the Taupō Volcanic Zone (TVZ), New Zealand have shown evidence for crystallization and storage on the order of decades to centuries prior to eruption.

Magma plumbing beneath Anak Krakatau volcano, Indonesia: evidence for multiple magma storage regions
Contributions to Mineralogy and Petrology, 2011 Understanding magma plumbing is essential for predicting the behaviour of explosive volcanoes. We investigate magma plumbing at the highly active Anak Krakatau volcano (Indonesia), situated on the rim of the 1883 Krakatau caldera by employing a suite of thermobarometric models.

Mafic glass compositions: a record of magma storage conditions, mixing and ascent. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 The trans-crustal magma system paradigm is forcing us to re-think processes responsible for magma evolution and eruption. A key concept in petrology is the liquid line of descent (LLD), which relates a series of liquids derived from a single parent, and therefore tracks the inverse of the crystallization path.

, 2010 Improving our understanding of magma plumbing and storage remains one of the majorchallenges for petrologists and volcanologists today. This is especially true for explosivevolcanoes, where constraints on magma plumbing are essential for predicting dynamicchanges in future activity and thus for hazard mitigation. This study aims to investigate themagma

The trigger mechanism of low-frequency earthquakes on Montserrat. [PDF]
, 2006 A careful analysis of low-frequency seismic events on Soufrie`ere Hills volcano, Montserrat, points to a source mechanism that is non-destructive, repetitive, and has a stationary source location.

Warm storage for arc magmas [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance The increasingly popular notion that steady-state magma chambers are highly crystallized, and thus only capable of erupting during brief (<1 ka) reheatings, implies that melt detection beneath volcanoes warns of imminent eruption.

Millennial storage of near-Moho magma [PDF]
Science, 2019 Millennial magma reserves Lava erupts after being stored as magma deeper underground. Silica-rich magmas characteristic of volcanoes like Pinatubo are stored for thousands to hundreds of thousands of years. However, we have little understanding of the time scales for deeper basaltic magma like that supplying Icelandic volcanoes ...

Modeling the Intermittent Lava Lake Drops Occurring Between 2015 and 2021 at Nyiragongo Volcano
Geophysical Research Letters, 2023 Between 2015 and 2021, Nyiragongo's lava lake level experienced a linear increase punctuated by fast intermittent drops. These drops occurred synchronously to seismic swarm at approximately 15 km below the surface and extending laterally NE from the ...
