Eruption timeline, recording the date, the observer, the method of observation (airplane vs. ground), the emplacing event and texture, and when applicable, active vents (located in the purple polygon), effusion rates, and flow front speeds. The mapped areal emplacement and temporal stratigraphy interpretation is from this study. ‘S. Thor.’ = Sigurđur Thorarinsson, the primary investigator during the eruption (Thorarinsson, 1963). The asterisk indicates a localized observation of a lava river coming from the west vent
