We review here three main (first-order) mechanisms of stress variation able to influence the triggering of volcanic eruptions and the possible impact on eruption dynamics. They are shortand long-term unloading, seismic energy effects, and changes in far field stress due to geodynamic processes. We present an equilibrium equation for rupture of magma chamber and opening of a dyke up to the surfa...
WestMata is a 1200mdeep submarine volcano where explosive boninite eruptions were observed in 2009. The acoustic signatures from the volcano’s summit eruptive vents Hades and Prometheus were recorded with an in situ (~25m range) hydrophone during ROV dives in May 2009 and with local (~5 km range) moored hydrophones between December 2009 and August 2011. The sensors recorded low frequency (1–40 ...
macroH2A is an H2A variant with a highly unusual structural organization. It has a C-terminal domain connected to the N-terminal histone domain by a linker. Crystallographic and biochemical studies show that changes in the L1 loop in the histone fold region of macroH2A impact the structure and potentially the function of nucleosomes. The 1.6-A X-ray structure of the nonhistone region reveals an...
The following propositions are true: (1) Let X be a set, p be a permutation of X, and x, y be elements of X. Then p +· (x, p(y)) +· (y, p(x)) is a permutation of X. (2) Let f be a function and x, y be sets. Suppose x ∈ dom f and y ∈ dom f. Then there exists a permutation p of dom f such that f +· (x, f(y)) +· (y, f(x)) = f · p. Let X be a finite non empty subset of R. The functor minX yielding ...
