title: Elevation of the lava lake in Halema?uma?u crater, K?lauea Volcano, from 2009 to 2018

description: This data release includes measurements of the surface elevation of the lava lake within Halema?uma?u crater, at the summit of K?lauea Volcano, during the 2008-2018 summit eruption (Patrick and others, 2021). 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 K?lauea?s 2008-2018 summit lava lake. The measurement intervals range from 1 s 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 (Anderson and others, 2019). Lava lake level provides unique insight into the deeper magmatic system, as well as constraints on shallow outgassing processes (Anderson and others, 2015; Patrick and others, 2016, 2019a). As a proxy for the pressure of the underlying magma reservoir, lava level can be a useful monitoring tool for eruption forecasting (Orr and others, 2015; Patrick and others, 2015). This data release provides a record of lava lake level at K?lauea?s summit that encompasses numerous flank eruptive events and several intrusions (Orr and others, 2015; Patrick and others, 2019c), as well as hundreds of deflation-inflation cycles in the summit reservoir (Anderson and others, 2015). The lake level changes reflect not only local changes in the summit reservoir, but also influence from the Pu?u???? eruption on K?lauea?s East Rift Zone (ERZ) that was concurrent with the summit eruption. These interactions between the summit and ERZ magmatic systems provide a series of complex controls on lake level and a rich dataset for new insight (Patrick and others, 2019a,b). As only a handful of lava lakes exist on Earth, just a few long-term datasets of lava lake level exist. These are reviewed in Patrick and others (2019a) and include 1) the early 1900s era of lake activity in Halema?uma?u, 2) several years of lake activity during the Mauna Ulu eruption on the ERZ (Tilling and others, 1987), 3) lake level during the 1990s (Denlinger and others, 1997) and 2009-2018 for the Pu?u ???? eruption (Orr and others, 2015; Patrick and others, 2019c), and 4) a record from 1953 to 2011 for Nyiragongo?s lava lake, which includes two major, destructive flank eruptions (Burgi and others, 2014). The dataset included in the current data release provides a record of lava lake level that is unique for its combination of long duration and high measurement rate. The data compiled here have been presented previously, in parts, in the following publications: Anderson and others (2015, 2019), Orr and others (2015), and Patrick and others (2014, 2015, 2018, 2019a,b,c, 2020, 2021). These studies have addressed some of the main processes driving lava lake fluctuations, but many other aspects of the lake level behavior are not fully understood and deserve further study. A small portion of the measurements were collected by the following colleagues: Steve Anderson, Adam Lewinter, David Finnegan, Gerald Bawden, Lil Desmither, Lopaka Lee, and Carolyn Parcheta.
