A lava lake within Halema‘uma‘u produced nighttime glow that was visible via HVO’s Webcam during the past week. The lava lake level was relatively steady, hovering around 35 m (~115 ft) below the rim of the Overlook crater. A rockfall from the Overlook crater wall triggered a small explosive event on July 23, bombarding the closed Halema‘uma‘u visitor overlook with spatter.
On KÄ«lauea’s East Rift Zone, lava flows from Pu‘u ‘Ō‘Å’s northeast flank vent continued to advance slowly toward the northeast, reaching to about 2.4 km (~1.5 miles) from the vent by mid-week. Pu‘u ‘Ō‘Œs crater floor continued to subside slowly.
No earthquakes were reported felt during the past week on the Island of Hawai‘i.
