From: Gas flux cyclic regime at an open vent magmatic column inferred from seismic and acoustic records
Vertical ground velocity seismogram at RFR (black) and infrasonic signal recorded by an element of the infrasound array (blue) during the 6 hours following the UTC time denoted on each y-axis on July 28, 2014. Both traces show a similar characteristic cycle in amplitude fluctuation. Grey and blue shaded periods are magnified in Figs 3b and 4a respectively.
