A lava lake has been present within the Halema`uma`u Overlook vent over the past week, resulting in night-time glow visible from the Jaggar Museum. The lake, which is deep within the vent cavity and visible by Webcam, started the week at a relatively high level. By Thursday, October 13, however, the day of this writing, the level had dropped considerably in response to the deflation phase of a summit deflation-inflation cycle.
The September 21 fissure, on the upper east flank of Pu`u `O`o cone in Kilauea’s east rift zone, erupted lava onto the surface through at least the first half of the past week. As with the Halema`uma`u lava lake, the activity level at Pu`u `O`o declined in response to the summit deflation-inflation cycle. As of Thursday, webcam views were insufficient to determine if lava was still erupting at Pu`u `O`o. Regardless, eruptive activity will likely resume after deflation switches back to inflation.
No earthquakes beneath Hawai`i Island were reported felt this past week.
