Time series of Kīlauea Volcano's lower East Rift Zone lava-flow maps, May 2 - August 14, 2018

During Kīlauea Volcano's lower East Rift Zone (LERZ) eruption, lava-flow maps were generated on a near-daily basis and published on the Hawaiian Volcano Observatory webpage. For the first week of the 2018 LERZ eruption, lava flows proved difficult to map, as they stayed close to the fissures in Leilani Estates, where vegetation obscured aerial views of their margins. Later, as the lava inundation in lower Puna grew more expansive, satellite views became the preferred method of mapping the flow field. Equally challenging was the rate at which some LERZ lava flows advanced, making a newly created map nearly obsolete by the time it was published. This time series shows the evolution of maps for the 2018 LERZ eruption, from May 2, 2018 to August 14, 2018.
