The vulcanian regime, typically associated with viscous magma, results from the disruption of a conduit plug or dome that fails under a sufficiently high pressure gradient in the underlying magma (Clarke et al. The gas flow associated with an explosion contains varying amounts of ash resulting from magma fragmentation or from plug rubble.

Melson (1989) and Barboza and Melson (1990) suggested that the more intense explosions were related to the formation of a lava cap, while smaller explosions (whooshes) with the extended chugs were related to a more open condition. In any case, the existence of the small acoustic waveforms, asymmetrical in favour of the rarefaction peak, which are typical of strombolian explosions, poses the question of the mechanisms of gas release at volcanoes with intermediate magma composition. ta.queueForLoad : function(f, g){document.addEventListener('DOMContentLoaded', f);})(function(){ta.trackEventOnPage('postLinkInline', 'impression', 'postLinks-93164934', '');}, 'log_autolink_impression');Costa Rica, and then of driving on their roads. https://doi.org/10.1029/JB091iB09p09543, Bani P, Harris AJL, Shinohara H, Donnadieu F (2013) Magma dynamics feeding Yasurs explosive activity observed using thermal infrared remote sensing. https://doi.org/10.1016/S0377-0273(03)00254-3, Suto S, Sakaguchi K, Watanabe K, Saito E, Kawanabe Y, Kazahaya K, Takarada S, Soya T (1993) Dynamics of flowage and viscosity of the 1991 lava of Unzan Volcano, Kyushu.

Hence, high temperatures contribute to lower viscosity in a rapidly decompressed andesitic magma and low temperatures contribute to increased viscosity in a slowly decompressed magma.
