Kīlauea continues to erupt at its summit and East Rift Zone. The summit lava lake level varied between about 45 and 70 m (148–230 ft) below the vent rim within Halemaʻumaʻu Crater. On the East Rift Zone, scattered lava flow activity remained within about 6 km (4 mi) of Puʻu ʻŌʻō.

Mauna Loa is not erupting. The seismicity rate continues above long term background, though it has not increased above rates observed in recent months. In the last week, earthquakes occurred mostly beneath Mauna Loa’s upper Southwest Rift Zone at depths less than 5 km (3 miles). Continuous GPS measurements continue to show deformation consistent with inflation of magma reservoirs beneath Mauna Loa.

(EQ report) One earthquake was reported felt in the past week across the Hawaiian Islands. On December 1, at 9:02 am a magnitude 3.1 earthquake occurred 19 mi (30 km) west-northwest of Hilo at a depth of 17 mi (28 km).

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 25-December 3, 2015. Images courtesy of USGS/HVO

This satellite image was captured on Monday, November 30, by the Advanced Land Imager instrument onboard NASA's Earth Observing 1 satellite. The image is provided courtesy of NASA's Jet Propulsion Laboratory. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds. The image shows that scattered breakouts continue to be active northeast of Puʻu ʻŌʻō in two main areas. First, small scattered breakouts are active as far as 5.8 km (3.6 miles) from the vent on Puʻu ʻŌʻō, continuing the activity we have seen over the past several months. Second, the breakout that began on November 25 continues to be active, but this breakout is still relatively minor and extends no farther than 2 km (1.2 miles) from Puʻu ʻŌʻō.
