Fig. 3: Modeled dynamics of the bubble grows and magma pressure change.
From: Deep long period volcanic earthquakes generated by degassing of volatile-rich basaltic magmas
Results are shown for the bubble number density of 1013 m−3, four different water contents indicated with wt% values in respective plots, and for CO2 content computed for 828 MPa (red circles in Fig. 2). a Evolution of the bubble radius. b Evolution of magma pressure Pm (Pg values are shown with gray lines). c Evolution of the CO2 content in bubbles. d Ground velocities estimated for a source located at a 30 km distance from the receiver (Additional information provided in Methods). e Example of real seismogram (east-west component at station LGN, Supplementary Fig. 1). f Fourier amplitudes computed from synthetic and real (gray line) signals.
