(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. During the past week, the summit lava lake level was relatively stable, varying between about 35 and 38 m (115–125 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, scattered lava flow activity remains within about 6 km (4 mi) of Puʻu ʻŌʻō, and is not currently threatening nearby communities.

Mauna Loa is not erupting. Seismicity remains elevated above long-term background levels, with earthquakes occurring mostly beneath the volcano’s upper Southwest Rift Zone at depths less than 5 km (3 mi) during the past week. Continuously recording GPS instruments show 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.

There were no earthquakes reported felt on the Island of Hawai‘i during the 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. January 21-28, 2016. Images courtesy of USGS/HVO
