(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 lava level fluctuated between 45 and 51 m (148 and 167 ft) below the rim of the Overlook crater.

On Kīlauea’s East Rift Zone, the Kahauale‘a 2 flow continued to be active northeast of Pu‘u ‘Ō‘ō. The active flow front was 8.2 km (5.1 miles) northeast of the vent on Pu‘u ‘Ō‘ō on Friday, March 21. Webcam images indicate that small, lava-sparked forest fires continue to burn.

There were three felt earthquake in the past week on the island of Hawai‘i. On Thursday, March 20, 2014, at 4:56 p.m., HST, a magnitude-3.4 earthquake occurred 7.5 km (4.5 mi) southeast of Pu‘u ‘Ō‘ō Crater at a depth of 9 km (5 mi). On Saturday, March 22, at 7:10 a.m., a magnitude-2.4 earthquake occurred 3.9 km (2.4 mi) northwest of ‘Opihikao at a depth of 3.8 km (2.4 mi). On Tuesday, March 25, at 8:05 p.m., a magnitude-2.5 earthquake occurred 4.0 km (2.5 mi) notheast of Hōnaunau at a depth of 13.2 km (8.2 mi).
