Figure 3

Magma chamber deflation rate (or discharge rate) versus cloud height on January 26 and 27. Double logarithmic plot of eruption echo height against geodetic deflation rate of the magma chamber for the sub-Plinian and SC events on January 26 and 27 (the events in Figure 2b). A fitting line with power-law scaling is also shown (0.255 power, R =0.878). The scale at the top of the figure represents discharge rate Q (kg s−1) calculated from the geodetic deflation rate D (m3 s−1) using the relationship Q =2.5 , where ρ is density of dense rock (set to be 2,500 kg m−3).
