Kīlauea summit eruption four-month anniversary

April 20 was the four-month anniversary of Kīlauea's ongoing summit eruption in Halema‘uma‘u. This animated GIF features approximately one thermal image for each day of the eruption and demonstrates eruptive activity over the past four months. At 9:30 p.m. HST on December 20, 2020, vents opened in the northwest and north walls of Halema‘uma‘u, erupting lava and vaporizing

April 16, 2021: Overview of Halema‘uma‘u lava lake western portion

During a Kīlauea summit helicopter overflight on Friday, April 16, an HVO scientist captured this photo of the erupting western fissure and surrounding lava lake within Halema‘uma‘u. The active western potion of the lava lake, as seen here, measured approximately 300 m (984 ft) from end-to-end at the time. USGS image.
