USGS has a page on the history of Kilauea here: https://www.usgs.gov/volcanoes/kilauea/science/geology-and-h..., which also has some links on some of the eruptions in recorded history.

Probably the closest thing to what you're looking for is here: https://www.usgs.gov/media/images/kilauea-caldera-simplified..., which lists the age of the most recent lave flows as of 2008 (when Halema'uma'u started filling up again). The 2018 eruption caused another caldera collapse within the crater, enlarging Halema'uma'u and creating a new mini-caldera that's labeled as the "down-dropped block" in subsequent maps, e.g. https://www.usgs.gov/maps/october-5-2021-kilauea-summit-erup... ... although, since then, Halema'uma'u has erupted enough lava to more or less fill the entire down-dropped block, see, e.g., the most recent map: https://www.usgs.gov/maps/november-25-2025-kilauea-summit-er...
