TL;DR: In the field of volcano seismology, a wide variety of signals originating in the transport of magma and related hydrothermal fluids and their interaction with solid rock have been studied as discussed by the authors.

TL;DR: In this article, the authors present a new semi-empirical constitutive model for bubble-bearing suspensions, which is valid for steady and unsteady flow and large strains and strain-rates.

TL;DR: In this paper, the authors review the diversity of infrasound signals generated by a wide variety of volcanic eruptions, from hawaiian to plinian, and the physical processes inferred to produce them.

TL;DR: In this paper, the authors provided data from stratigraphic and sedimentologic analyses of 62 sections of the first unequivocal blast-like deposits in Merapi's recent history, which formed Stage 4 of the multi-stage 2010 eruption, the most intense eruptive episode at Merapi since 1872.

TL;DR: In 2010, satellite-borne commercial Synthetic Aperture Radar (SAR) enabled frequent monitoring of Merapi volcano's 2010 eruption, which lasted 12 days (26 October-7 November, 2010) as discussed by the authors.

TL;DR: In this paper, the authors analyzed the results of 1969 questionnaires and conducted a series of interviews with community leaders and emergency officials and found that trust in the Indonesian government and volcanologists was very high after the 2010 Merapi eruption, and multiple modes of communication were used to relay warnings and evacuation orders.

TL;DR: In this article, the authors investigated the geochemistry, petrology, and pre-eruptive conditions of magmas erupted in 2006 and 2010 at Merapi and found that the latter was driven by the same processes and magma types.

TL;DR: In this paper, the authors defined volcanic unrest as the deviation from the background or baseline behaviour of a volcano towards a behaviour which is a cause for concern in the short-term because it might prelude an eruption.

TL;DR: In this article, the impact of the 2010 Merapi volcano eruption was studied using a combination of remote, field, laboratory, and GIS assessments and was able to enter the affected areas safely and before their disturbance by rains or human activity.

TL;DR: In this article, the authors used cooling and decompression experiments to investigate the crystallization of a hydrous basaltic-andesite magma, where the driving force for undercooling of feldspar is equal whether in the direction of cooling or decompression.

TL;DR: In this article, the Puyehue-Cordon Caulle volcanic complex, southern Chile, was studied by X-ray computed microtomography and their permeability was modeled by lattice Boltzmann simulations.

TL;DR: In this paper, a volume estimation model is developed and applied to the Auckland Volcanic Field in New Zealand, where a basaltic monogenetic volcano is categorised in six parts.

TL;DR: In this paper, the authors observed twenty-three distinct episodes of volcanic lightning during the Redoubt Volcano in March and April 2009 and observed two phases of electrical activity: the explosive phase and the plume phase.

TL;DR: The 2010 pyroclastic density currents (PDC) at Merapi have presented a rare opportunity to collect a uniquely detailed dataset of the source, extent, lateral variations and impact of various PDC deposits on a densely populated area as discussed by the authors.

TL;DR: In this article, the authors assess how well they did with their predictions for specific facets of volcano remote sensing in 2000 the advances made over the most recent decade, and attempt a new look ahead to the next decade.

TL;DR: The 2010 VEI 4 eruption of Merapi volcano deposited roughly ten times the volume of pyroclastic materials of the 1994 and 2006 eruptions, and is recognized as one of the most intense eruption since 1872 as discussed by the authors.

TL;DR: In this article, the results of time-dependent local earthquake tomography for the Kluchevskoy group of volcanoes in Kamchatka, Russia, were presented, and the results were supported by synthetic tests that recover a common 3D model based on data corresponding to different time windows.

TL;DR: The 2009 eruption of Redoubt Volcano, Alaska was particularly well monitored for volcanic gas emissions as mentioned in this paper, and 35 airborne measurements of CO 2, SO 2, and H 2 S emission rates that span from October 2008 to August 2010 were reported.

TL;DR: In this paper, the global volatile flux from subaerial volcanoes at subduction zones was estimated based on a compilation of fluxes from various sources, including persistent degassing, hot and cold springs, soil degassing and eruptions.

TL;DR: The 2010 Merapi eruption was the first large explosive eruption of the volcano that has been instrumentally observed as discussed by the authors, and the main characteristics of the seismic activity during the pre-eruptive period and the crisis are presented and interpreted in this paper.

TL;DR: In the 2009 eruption of Redoubt Volcano, Alaska, a gliding harmonic tremor occurred prominently before six nearly consecutive explosions during the second half of the eruptive sequence.

TL;DR: In this paper, the authors investigated the effect of temperature on two carbonate rocks that have been chosen to represent the deep, heterogeneous sedimentary substratum under Mt. Etna volcano and found that high in-situ temperatures significantly reduced the strength of the carbonates and altered their deformation behaviour.

TL;DR: In this paper, the authors presented a new compilation of newly corrected bottom-hole temperature data in the French part of the Upper Rhine Graben, where the Soultz-sous-Forets temperature anomaly is locked beneath a local horst structure.

TL;DR: In this article, a MATLAB software package for the most common models used to interpret deformation measurements near faults and active volcanic centers has been developed, where the emphasis is on analytical models of deformation that can be compared with data from the Global Positioning System (GPS), InSAR, tiltmeters and strainmeters.

TL;DR: The 2010 Merapi volcano eruption was the second most deadly in the historic record of this volcano, claiming over 380 lives by relating the observations of this eruption with detailed examination of deposit distribution, stratigraphy and sedimentology, including the valley controlled block-and-ash flows (BAFs) and widespread, energetic pyroclastic surges as mentioned in this paper.

TL;DR: In this paper, the authors detail the changes of dome morphology that were monitored by taking successive photographs from similar positions, showing that the summit remains inflated after each eruption, i.e., no significant deflation occurs following eruptions.

TL;DR: In this article, the authors developed a new axisymmetric analytic model of surface uplift upon sills and laccoliths, based on the formulation of a thin bending plate lying on an elastic foundation.

TL;DR: In this article, the authors present an analysis of post-4 April lava dome growth using an oblique photogrammetry approach that provides a safe, rapid, and accurate means of measuring dome growth.

TL;DR: In this paper, the authors track the evolution of seismic activity at Redoubt Volcano, Alaska, using a network of five to ten seismometers within 22 km of the volcano's summit.

TL;DR: In this paper, the authors present a seismic chronology of the Redoubt Volcano eruption and places it in context with the variety of other geological and geophysical data that were recorded during the eruptive period.
