“…Considering that in a natural system, gas bubbles concentrate in the upper part of the magma column, the conductivity derived from the measurements on the lava lake samples may be considered as a good estimate of that of the upper part of the magma column, as confirmed by the in-situ measurements performed at Kīlauea Iki lava lake (Smith et al, 1977) and lava flow (Bartel et al, 1983). Such low conductivity values are commonly associated with low density materials in agreement with the recent estimated densities of the lava lake (Carbone et al, 2013).…”

Before the 2018 collapse of the summit of Kīlauea volcano, a ca. 200 m in diameter lava lake inside of Halema'uma'u crater was embedded in a very active hydrothermal system. In 2015, we carried out an electrical conductivity survey and the data were inverted in 3D. The lack of conductivity contrast precludes distinguishing the lava column from the surrounding hydrothermal zones. Laboratory measurements on samples from the lava lake show that the conductivity of magma is significantly lower than that of hydrothermal zones but the high vesicularity of the upper part of the lava lake may decrease its macroscopic conductivity. Based on the 3D conductivity model, we distinguish at least two types of hydrothermal circulations: 1) one guided by the collapse faults of Halema'uma'u crater and by the magmatic column of the lava lake, and 2) another guided by previous caldera faults and fractures related to intrusions. We observe that the location of the faults formed during the 2018 collapse of the summit was greatly influenced by the hydrothermally altered zones.

In the quadrennium 1983–1986 there has been an exceptional increase in studies concerning volcanoes. It has also been an active four years for the world's volcanoes, including some of the most devastating events known and major alerts at three of the world's calderas. The range of methods used to study volcanoes has also multiplied, embracing the use of many new techniques. All of this makes the task of selecting topics and papers for inclusion in this review extremely difficult. We cannot attempt to be comprehensive in such a short review. Our investigations for material stopped approximately in mid‐August, 1986. [Tilling and Newhall] (in press) are preparing a review of volcanology in 1987.
