Comparative volumes of lava emitted during major eruptions:
"Between 11 and 18 September 2016, 7 million m³ of lava were emitted at the surface, which makes 1 million per day on average ... it is quite uncommon with exceptions.:
- Eruption of January 5, 2002: 13 million m³ for 12 days of eruption
- Eruption of 22 August 2003 (peak Payankë): 6 million m³ for 6 days of eruption
- Eruption of 17 February 2005: 19 million m³ to 10 days of eruption
- Eruption of avrill 02, 2007 (peaks Tremblet): 240 million m³ for 30 days of eruption
