June 3, 2024 —Kīlauea Southwest Rift Zone eruption reference map, updated as of 10PM HST

A new eruption began along Kīlauea's Southwest Rift Zone on June 3, 2024, and this map depicts activity on the eruption's first day. New lava flows are shown in red, only covering about 88 acres (36 hectares) of ground within relatively short distances of the eruptive fissures. Four eruptive fissures—marked in yellow—were active on June 3, and they have been informally named fissures 1–4, running from uprift (northeast) to downrift (southwest). The eruption is occurring in close proximity to older flows from Kīlauea's December 1974 eruption.
