Whole-rock oxygen isotope ratios as a proxy for the strength and stiffness of hydrothermally altered volcanic rocks
Michael J. Heap,Valentin R. Troll,Chris Harris,H. Albert Gilg,Roberto Moretti,Marina Rosas-Carbajal,Jean-Christophe Komorowski,Patrick Baud +7 more
TL;DR: In this paper , the authors explore the possibility of using whole-rock δ18O and δD values and water contents, metrics that can potentially track alteration, to estimate the strength (compressive and tensile) and Young's modulus (i.e. "stiffness") of altered (acid-sulphate) volcanic rocks from La Soufrière de Guadeloupe (Eastern Caribbean).

Diverse magma storage and major and volatile magma composition: What are the implications on the eruptive style across a volcanic arc? An example of the Lesser Antilles Arc
A. T. Metcalfe,Séverine Moune,Jean-Christophe Komorowski,Richard Robertson,T. Christopher,Erouscilla P. Joseph,Roberto Moretti +6 more
TL;DR: In this article , the authors highlight the variations observed in magma storage, which is described as a vertically extensive trans crustal mush system, and hypothesise that across the arc there are generally three levels of the mush storage system.

A bonded-particle model for rock
D.O. Potyondy,Peter Cundall +1 more
TL;DR: In this paper, a numerical model for rock is proposed in which the rock is represented by a dense packing of non-uniform-sized circular or spherical particles that are bonded together at their contact points and whose mechanical behavior is simulated by the distinct element method using the two-and three-dimensional discontinuum programs PFC2D and PFC3D.

The 2010 explosive eruption of Java's Merapi volcano—A ‘100-year’ event
Surono,Philippe Jousset,John S. Pallister,Marie Boichu,M. Fabrizia Buongiorno,Agus Budi-Santoso,Fidel Costa,Supriyati Andreastuti,Fred Prata,David J. Schneider,Lieven Clarisse,Hanik Humaida,Sri Sumarti,Christian Bignami,Julia P. Griswold,Simon Carn,Clive Oppenheimer,Clive Oppenheimer,Franck Lavigne +18 more
TL;DR: In this paper, the authors show that the magnitude of precursory signals (seismicity, ground deformation, gas emissions) were proportional to the large size and intensity of the 2010 Merapi volcano eruption.

How local stresses control magma-chamber ruptures, dyke injections, and eruptions in composite volcanoes
TL;DR: In this paper, a review of analytical and numerical models of local stresses around magma chambers, as well as analytical models and numerical examples of dyke-injection and eruption frequencies are presented.

A Review of the Tensile Strength of Rock: Concepts and Testing
TL;DR: In this article, a review of the tensile strength of rock was conducted to determine the relationship between DTS and BTS and examine the validity of estimating tensile strengths from other measured properties, such as the crack initiation (CI) threshold.
