(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 40 and 50 m (131–164 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, scattered lava flow activity remained within about 6.1 km (4 mi) of Puʻu ʻŌʻō.

Mauna Loa is not erupting. The seismicity rate is elevated above background levels, but has not increased over rates observed during the past six months. Continuous GPS measurements continue to show deformation consistent with inflation of magma reservoirs beneath Mauna Loa.

There were no earthquakes reported felt on the Island of Hawai‘i this past week.

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 19-25, 2015. Images courtesy of USGS/HVO
