This data release includes measurements of the surface elevation of the lava lake within Halemaʻumaʻu crater, at the summit of Kīlauea Volcano, during the 2008-2018 summit eruption.

A view of Kīlauea’s 2008-2018 summit lava lake at dusk. The lava lake was contained within a crater informally called the "Overlook" crater (due to its position immediately below the former Halema‘uma‘u visitor overlook), and this crater was set within the larger Halema‘uma‘u Crater. The photo was taken from the rim of Halema‘uma‘u Crater. The lava lake was about 50 m (160 ft) below the rim of the Overlook crater. The level had dropped slightly over the past day, leaving a black veneer of lava on the crater walls just above the current margin and easily visible in this photograph. In the southeast portion of the lake, a persistent spattering source ejected spatter more than halfway up the Overlook crater walls.

The data were measured by several instruments (laser rangefinder, webcams, lidar) and are compiled here to provide the most complete dataset yet available on the elevation of Kīlauea’s 2008-2018 summit lava lake. 



The measurement intervals range from 1 second to 1 day, with most of the 9-year period covered by hourly measurements.  The dataset begins with daily measurements of the emergent lake in 2009 and 2010.  After 2010, continuous lake activity was tracked with hourly measurements of lava level that continued into 2018.  The dataset ends with a high-precision (1 Hz) record of the lake draining as the 2018 lower East Rift Zone eruption drew magma from the summit reservoir, terminating the summit lava lake activity in May 2018.

The plume was light at the time of the overflight, allowing a view of the southern wall, which recently experienced two collapses exposing the lighter wall rock beneath.
