At Kīlauea's summit, the vent within Halema`uma`u Crater is still emitting elevated amounts of volcanic gas, resulting in high concentrations of sulfur dioxide downwind. Glow from the vent was visible at night through the past week, and rare views into the vent by HVO scientists found that the lava surface is still present about 205 m (675 feet) below the floor of Halema`uma`u Crater.

No earthquakes beneath Hawai`i Island were reported felt this past week.
