1 Introduction The effusion rate of lava during a volcanic eruption is of fundamental importance in volcanology, given its direct association with hazard. In basaltic systems, effusion rate exerts a primary control on lava flow length [Walker et al., 1973; Harris and Rowland, 2009] and is also a critical input to quantitative models of lava flow

Contact UsFresh lava from Fagradalsfjall volcano eruption in Iceland, 2023. Lava is molten or partially molten rock that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F).
