A lava lake present within the Halema`uma`u Overlook vent during the past week resulted in night-time glow that was visible from the Jaggar Museum overlook. The lake, which is normally about 90–115 m (295–377 ft) below the floor of Halema`uma`u Crater and visible by HVO`s Webcam, rose and fell slightly during the week in response to a series of deflation-inflation cycles.
On Kilauea`s east rift zone, surface lava flows were active on the pali and upper coastal plain, in Royal Gardens subdivision, over the past week. As of Thursday, March 29, the flows on the coastal plain had made significant progress towards the coast but were still about 1.6 km (1 mile) from the ocean.
One earthquake beneath Hawai`i Island was reported felt this past week. A magnitude-4.9 earthquake occurred at 10:47 a.m., HST, on Saturday, March 24, 2012, and was located 1 km (1 mi) west of Honomu at a depth of 44 km (27 mi).
