Mass eruption rates obtained by the pulse velocity derived model (PVDM) are compared with results from plume height models (PHM) and infrasound derived values. Remarks: 1) Using observed plume heights of 2.9–3.3 km as input parameter, 2) using a windspeed of 20 m/s at 500 hPa (~5.2 km height) as input parameter, 3) cylindrical conduit with a diameter of 50 m was assumed, and 4) source diameter of 6 m was assumed, 40–75 % of total diameter according to Dürig et al. (2015); see text for details
