Lava erupted sporadically within the crater at Puu Oo over the past week, with activity increasing during the inflation phase of deflation–inflation cycles (DI events) and decreasing during the deflation phase.

The lava is more than 95 m (~300 ft) below the east rim of Puu Oo, and no lava is erupting outside of the crater.

A small lava lake was also present deep within the Halemaumau Overlook vent over the past week during periods of DI inflation. During periods of DI deflation, the lava lake dropped to a lower level and crusted over. Several small rock falls within the vent cavity also occurred during the week.

Volcanic gas emissions remain elevated, resulting in relatively high concentrations of sulfur dioxide downwind.

No earthquakes beneath Hawaii Island were reported felt this past week.
