A lava lake within Halemaʻumaʻu 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 Kīlauea’s East Rift Zone, the Kahaualeʻa 2 flow continued to be active northeast of Puʻu ʻŌʻō. The active flow front was 8.2 km (5.1 miles) northeast of the vent on Puʻu 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). On Wednesday, March 19, at 11:08 a.m., a magnitude-2.7 earthquake occurred 2 km (1 mi) southwest of Pa`auilo at a depth of 16 km (10 mi).
