A lava lake within HalemaÊ»umaÊ»u produced nighttime glow that was visible via HVO’s Webcam during the past week. The lava level fluctuated between 38 and 58 m (125 and 190 ft) below the rim of the Overlook crater.

On KÄ«lauea’s East Rift Zone, the KahaualeÊ»a 2 flow continued to be active northeast of PuÊ»u ʻŌʻō. The active flow front was 8.2 km (5.1 miles) northeast of the vent on PuÊ»u ʻŌʻō on Wednesday, March 19. Webcam images indicate that small, lava-sparked forest fires continue to burn.

Two earthquakes were reported felt on the Island of Hawai‘i in the past week. On Thursday, March 13, 2014, at 1:25 p.m., HST, a magnitude-3.5 earthquake occurred 8 km (5 mi) southwest of Kawaihae at a depth of 11 km (7 mi).
