June 2, 2026 — Kīlauea lava flow and tephra fall map following episode 48
This map shows lava flow and tephra accumulation at the summit of Kīlauea volcano associated with episode 48 of the ongoing eruption in Halemaʻumaʻu that started on December 23, 2024, using data recorded by the Italian Space Agency's (ASI) COSMO-SkyMed Second Generation satellite constellation. These maps combine cross-polarized radar amplitude images taken on two different dates (on May 25 and June 2, 2026), along with interferometric coherence from the time between those dates. In the maps, unchanged barren areas are represented in blue/purple, vegetated areas appear in yellow/light green, new deposits over barren land are shown in dark green, and the recent lava flows in red. Public viewing areas within Hawaiʻi Volcanoes National Park are indicated with white squares; these can be temporarily closed for public safety.
