Southeast embayment of active lava lake, Halema‘uma‘u, Kīlauea - April 26, 2022

Telephoto view looking east of the southeast embayment of the active lava lake within Halema‘uma‘u, Kīlauea, on April 26 2022. In this photo, lava from the active lava lake (silvery grey surface in lower left quadrant of photo) cascades into the southeast embayment (red surface). As the lava surface within the southeast embayment was constant during the several hour observation period, it appears that from the southeast embayment lava is plunging underneath the crater floor, contributing to the gradual rise of the crater floor surface.
