Summary
We depict changing eruptive features within the summit caldera of Kīlauea volcano, Island of Hawaiʻi with rapid-response digital elevation models (DEMs) acquired since a series of caldera-filling effusive eruptions began on December 20, 2020. These eruptions follow the caldera collapse of 2018, with new lava progressively filling the approximately 1-cubic-kilometer pit that formed between May and August of that year. The majority of the provided DEMs were constructed via structure-from-motion (SfM) photogrammetry from either helicopter or uncrewed aircraft system (UAS) overflight images, with the remainder constructed via terrestrial laser scanning (TLS) from the Halemaʻumaʻu crater rim. These data were collected and processed using [...]

These data were collected and processed using streamlined techniques to provide rapid-response representations of topography inside the caldera, with mid-grade process settings and approximate georeferencing.

Material Request Instructions
The source data (images and TLS scans) will eventually be released to allow researchers to process the DEMs themselves.
Purpose
These rapid-response DEMs serve as the best-available depiction of topography inside Kīlauea caldera at time of their collection, therefore it is recommended that they only be used for situational awareness and general depictions of the 2020-present summit eruptions at Kīlauea, and not for research-level analysis. The U.S. Geological Survey (USGS) provides these data "as-is" for reference purposes but assumes no legal liability or responsibility resulting from the use or misuse of this product.
