Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake was relatively stable, with the lake level around 28-32.5 m (92–107 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, satellite imagery acquired on March 23 showed scattered lava flow activity within about 8 km (5 mi) of Puʻu ʻŌʻō. These flows were not threatening nearby communities.

Mauna Loa is not erupting. Seismicity remains elevated above long-term background levels, but no significant changes were recorded over the past week. GPS measurements show continued deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone of Mauna Loa, with inflation recently occurring mainly in the southwestern part of the magma storage complex.

Two earthquakes were reported felt on the Island of Hawai‘i during the past week. On Monday, March 21, 2016, at 9:28 a.m., HST, a magnitude-2.9 earthquake occurred 10.6 km (6.6 mi) north of Kawaihae at a depth of 23.4 km (14.6 mi). On Sunday, March 20, 2016, at 6:43 a.m., HST, a magnitude-4.6 earthquake occurred 14.3 km (8.9 mi) southeast of Waikoloa at a depth of 32.4 km (20.1 mi).

Time-lapse movie from images gathered from a temporary thermal camera looking into Pu’u ‘O’o Crater. The temperature scale is in degrees Celsius up to a maximum of 500 Celsius (932 Fahrenheit) for this camera model, and scales based on the maximum and minimum temperatures within the frame. Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures. March 17-24, 2016. Images courtesy of USGS/HVO
