A lava lake within HalemaÊ»umaÊ»u produced nighttime glow that was visible via HVO’s Webcam during the past week. Summit tiltmeters recorded minor variations, but overall the tilt level remains relatively steady. No deflation–inflation cycles (DI events) have occurred since mid-December. The lava lake level was about 44 m (144 ft) below the rim of the Overlook crater on Thursday, January 16.

On KÄ«lauea’s East Rift Zone, the KahaualeÊ»a 2 flow continued to advance slowly into the forest northeast of PuÊ»u ʻŌʻō. Satellite imagery showed the active front of the flow to be 7.8 km (4.8 miles) northeast of PuÊ»u ʻŌʻō on January 14.

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