The effusive eruption within the Halemaʻumaʻu lava lake ended on 19 June. This came with the official HVO statement yesterday.
The lava flow stopped to be active from the SW cinder cone and continues to form slabs of dark, solidified crust of the lava lake surface.
Sulfur dioxide (SO2) emissions have decreased to near pre-eruption background levels.
Therefore, the alert level for the volcano was lowered to Yellow.
The HVO continues: „Seismic activity—including eruptive tremor—in the summit region has been low since the eruption ceased. Over that period, gradual inflation has been recorded at summit tiltmeters. Overnight webcam views showed some incandescence from previously erupted lava as the lava proceeds to cool. There remains the potential for eruptive activity to resume in the near future at or near the summit of Kīlauea with little or no warning.“
