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 large 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 15, the flows were still about 2.7 km (about 1.7 miles) from the coast, and there was no active ocean entry.

Two earthquakes beneath Hawai`i Island were reported felt this past week, both on Tuesday morning, March 13, 2012, but on different islands. A magnitude-3.3 earthquake occurred at 10:27 a.m., HST, and was located 6 km (4 mi) southeast of Lana`i City, Lana`i, at a depth of 1 km (0.4 mi). A magnitude-3.4 earthquake occurred at 11:39 a.m., and was located 6 km (4 mi) south of Volcano Village at a depth of 2 km (1 mi).
