“…No fabrics indicative of shear (i.e., C-S fabric like described in fault gouges by Cashman et al (2008) and Kendrick et al (2012)) or preferred orientation of clasts is observed in these rocks. Devitrification textures or shapes suggestive of glass shards were not identified.…”

“…These are characteristic of dilation where brittle failure of magma results in tension gashes that rotate into sigmoidal shapes and are influenced by phenocryst and remnant pore location (Kendrick et al, 2012;Lavallée et al, 2013). The ragged pore walls in places indicate the magma was torn slowly (unlike straight failure planes produced at high shear rates; see Lavallée et al, 2013).…”

“…Endogenous growth proceeds as long as pervasive viscous and/or plastic deformation mechanisms dominate, but upon strain localization and shear rupture, growth may proceed exogenously (Watts et al, 2002), generating distinct nondestructive, low-frequency, seismic signals (Neuberg et al, 2006) and may, upon further seismic slip, erect spine-like structures (Kendrick et al, 2012). The buildup of internal gas pressure is a threat to the structural stability of lava domes.…”
