Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake level varied between about 31 and 47 m (102–157 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, scattered lava flow activity remained within about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻŠand was not threatening nearby communities.
Mauna Loa is not erupting. Seismicity remains elevated above long-term background levels, but no significant changes were recorded during 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 this past week. On Thursday, April 21, 2016, at 12:55 p.m., HST, a magnitude-3.1 earthquake occurred 9.9 km (6.1 mi) northwest of Mauna Kea Summit at a depth of 23.6 km (14.6 mi). On Saturday, April 16, at 8:39 a.m., HST, a magnitude-3.5 earthquake occurred 3.0 km (1.9 mi) southeast of Kīlauea Summit at a depth of 12.8 km (8.0 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. April 14-21, 2016. Images courtesy of USGS/HVO
