Abstract
We present elastic wave velocity and strength data from a suite of three volcanic rocks taken from the volcanic edifces of El Hierro and Tenerife (Canary Islands, Spain), and Stromboli (Aeolian Islands, Italy). These rocks span a range of porosity and are taken from volcanoes that sufer from edifce instability. We measure elastic wave velocities at known incident angles to the generated through-going fault as a function of imposed strain, and examine the efect of the damage zone on P-wave velocity. Such data are important as feld measurements of elastic wave tomography are key tools for understanding volcanic regions, yet hidden fractures are likely to have a signifcant efect on elastic wave velocity. We then use elastic wave velocity evolution to calculate concomitant crack density evolution which ranges from 0 to 0.17: highest values were correlated to the damage zone in rocks with the highest initial porosity.
