A mantle-driven surge in magma supply to Kīlauea Volcano during 2003–2007
TLDR
The supply of magma to Kīlauea Volcano, Hawai'i, was thought to have been steady over the past decades as discussed by the authors, but instead, the supply from the mantle doubled in 2003-2007, implying that hotspots can provide varying amounts of lava over just a few years.Abstract:
The supply of magma to Kīlauea Volcano, Hawai‘i, was thought to have been steady over the past decades. Measurements of deformation, gas emissions, seismicity and lava composition and temperatures show that instead magma supply from the mantle doubled in 2003–2007, implying that hotspots can provide varying amounts of magma over just a few years.read more

Magmas near the critical degassing pressure drive volcanic unrest towards a critical state
Giovanni Chiodini,Antonio Paonita,Alessandro Aiuppa,Alessandro Aiuppa,Antonio Costa,Stefano Caliro,Prospero De Martino,Valerio Acocella,Jean Vandemeulebrouck,Jean Vandemeulebrouck +9 more
TL;DR: It is proposed that magma could be approaching the CDP at Campi Flegrei, a volcano in the metropolitan area of Naples, one of the most densely inhabited areas in the world, and where accelerating deformation and heating are currently being observed.

Volcanology: lessons learned from synthetic aperture radar imagery
TL;DR: In this article, the authors review the contributions of satellite SAR imagery to volcano science, monitoring, and hazard mitigation, and explore the future potential for SAR in volcanology, which can then be used to develop new models of how volcanoes work and to improve quantitative forecasts of volcanic activity as a means of mitigating risk from future eruptions.

An overview of recent (1988 to 2014) caldera unrest: knowledge and perspectives
TL;DR: In this article, the best known unrest at calderas from 1988 to 2014, building on previous work and proposing an updated database, was reviewed. But none of the studies were purely hydrothermal or tectonic.

Precursory inflation of shallow magma reservoirs at west Sunda volcanoes detected by InSAR
Estelle Chaussard,Falk Amelung +1 more
TL;DR: In this paper, the authors used ALOS Interferometric Synthetic Aperture Radar (SAR) data over the entire west Sunda arc, Indonesia, home of 13% of the world's active volcanoes, to derive arc-wide time-dependent ground deformation data.

Insights into magma and fluid transfer at Mount Etna by a multiparametric approach: A model of the events leading to the 2011 eruptive cycle

TL;DR: In this article, a multiparametric approach, consisting of comparing volcanological, geophysical, and geochemical data, was applied to explore the volcano's dynamics during 2009-2011, and the inversion of ground deformation GPS data and the locations of the tremor sources were used to constrain both the area and the depth range of magma degassing, allowing reconstructing the intermediate and shallow storage zones feeding the 2011 cyclic fountaining NSEC activity.

Surface deformation due to shear and tensile faults in a half-space
TL;DR: In this paper, a suite of closed analytical expressions for the surface displacements, strains, and tilts due to inclined shear and tensile faults in a half-space for both point and finite rectangular sources are presented.

Precise point positioning for the efficient and robust analysis of GPS data from large networks
TL;DR: This work determines precise GPS satellite positions and clock corrections from a globally distributed network of GPS receivers, and analysis of data from hundreds to thousands of sites every day with 40-Mflop computers yields results comparable in quality to the simultaneous analysis of all data.

Radar interferogram filtering for geophysical applications
TL;DR: In this paper, a new adaptive filtering algorithm was proposed to dramatically lower phase noise, improving both measurement accuracy and phase unwrapping, while demonstrating graceful degradation in regions of pure noise.
