Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake level varied between about 27 m and 36 m (88–118 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, the June 27th lava flow may have stopped, but HVO scientists continue to watch for signs of activity. On the flanks of Pu‘u ‘Ō‘ō, only the eastern breakout remained active. As of June 8, this flow was 2.7 km (1.7 mi) long and continued to advance to the southeast. No lava flows were threatening nearby communities.

Mauna Loa is not erupting. A small earthquake swarm occurred beneath the volcano’s west flank on May 28–31. Most of these earthquakes were about 5–8 km (3–5 mi) deep, and the largest magnitude was 2.8. This swarm is expected behavior and does not represent a significant change for Mauna Loa. Seismicity rates have since decreased, but are still elevated above long-term background levels. Deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone continues, with inflation recently occurring mainly in the southwestern part of Mauna Loa’s magma storage complex.

No earthquakes were reported felt on the Island of Hawaiʻi 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. June 2-9, 2016. Images courtesy of USGS/HVO

This map shows recent changes to Kīlauea’s active East Rift Zone lava flow field. The area covered by the June 27th flow (which may be inactive) as of June 2 is shown in orange. The areas covered by the recent breakouts at Puʻu ʻŌʻō as of June 2 are shown in pink, while widening and advancement of the new breakouts as mapped on June 8 is shown in red. The northern breakout is inactive. Puʻu ʻŌʻō lava flows erupted prior to June 27, 2014, are shown in gray. Puʻu ʻŌʻō is at lower left.
