(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

Kīlauea continues to erupt at its summit and East Rift Zone. The summit lava lake level varied between about 55 and 79 m (180–260 ft) below the vent rim within Halemaʻumaʻu Crater. On the East Rift Zone, scattered lava flow activity remained within about 6.4 km (4 mi) of Puʻu ʻŌʻō.

Mauna Loa is not erupting. Small earthquakes continue to occur beneath the volcano’s summit and upper Southwest Rift Zone at rates slightly above background levels. GPS lines across the summit have shown no change, but flank crossing lines continue to extend, which is consistent with inflation of magma reservoirs beneath Mauna Loa.

One earthquake was reported felt on the Island of Hawaiʻi this past week. On Monday, November 16, 2015, at 04:12 a.m., HST, a magnitude-2.8 earthquake occurred 3.5 km (2.1 mi) south of Kawaihae at a depth of 31.8 km (19.7 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. November 12-19, 2015. Images courtesy of USGS/HVO
