Abstract: A textural examination of volcanic ash erupted from Santiaguito volcano in Guatemala coupled with an analysis of the geophysical signals indicates that rapid heating during fault friction can cause melting and vesiculation (development of bubbles) of hydrated silicic magma, thus strongly affecting magma strength and eruptive behaviour.
