Table 4 Statistical results for pulse volumes V trams and pulse masses m tot

From: Mass eruption rates in pulsating eruptions estimated from video analysis of the gas thrust-buoyancy transition—a case study of the 2010 eruption of Eyjafjallajökull, Iceland

Pulse type V trams (·105 m3) m tot (·105 kg)
Range 0.2–10.5 0.2–11.0
Average type 1 4.6 4.8
Average type 2 1.6 1.7
Wt. average 2.0 2.1
Wt. st. dev. 1.5 1.6
  1. These values are based on 16 representative pulses between 8 and 10 May 2010. The volumetric values were computed by applying Eq. (3); the mass values were obtained by multiplying V trans with a density of 1.05 kg/m3
