Kīlauea Caldera from HVO (4/24/14-5/2/14)

(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

A lava lake within Halema‘uma‘u produced nighttime glow that was visible via HVO’s Webcam during the past week. The lake level was relatively high and stable, staying between 30 m (98 ft) and 35 m (115 ft) below the rim of the Overlook crater.

On Kīlauea’s East Rift Zone, the active front of the Kahauale‘a 2 flow was 8.3 km (5.2 miles) northeast of its vent on Pu‘u ‘Ō‘ō when mapped on Monday, April 28. In addition, two other flows, fed from spatter cones on the northern and southern edges of the crater floor, sent small flows toward the north and southeast, respectively. While the fate of northern flow is not known, Webcam images indicated that, as of Thursday, May 1, the southern flow was still active. Poor views precluded views of the Kahauale‘a 2 flow, but it is expected to be active as well.

There were no earthquakes in the past week reported felt on the Island of Hawai‘i.
