Hawaii 24/7

KÄ«lauea is not erupting. At the summit, tiltmeters showed little change this week, except for a small deflation-inflation sequence.

A slight inflationary trend near and east of Puʻu ʻŌʻō suggests that magma may be refilling the middle East Rift Zone. Low seismicity and reduced gas emissions do not indicate that the magma is shallow, but HVO continues to closely monitor this area and will report any significant changes.

KÄ«lauea activity is greatly reduced, with low rates of seismicity, deformation, and gas emissions recorded this past week, and no active lava at the surface of the volcano since September 5.

Accordingly, HVO is lowering the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY. This means volcanic activity has decreased significantly but continues to be closely monitored for renewed activity. The Aviation Color Code is also being lowered from ORANGE to YELLOW.

Active lava has not been seen within the fissure 8 cone since September 5, and the high rates of seismicity and deflationary deformation at the summit stopped abruptly on August 4.

At KÄ«lauea’s lower East Rift Zone, the most recent significant incandescence visible within the fissure 8 cone was on September 15. At the summit of the volcano, seismicity and ground deformation remain low.

Putting together the evidence for such events is complicated, time-consuming, field-oriented research, but it paid dividends at KÄ«lauea by recognizing the large-scale cyclic behavior of the volcano during the past 2,500 years.

The combined sulfur dioxide emission rates at Kīlauea’s summit, Puʻu ʻŌʻō, and lower East Rift Zone remain at less than 1,000 tonnes per day—lower than at any time since late 2007.

Since the beginning of September, small lava flows have been observed within the fissure 8 cone, but none have extended outside the walls of the cone.

At KÄ«lauea’s lower East Rift Zone, lava intermittently erupted within the fissure 8 cone, but no lava flowed beyond the spillway. Residents in the lower Puna and KÄ«lauea summit areas should stay informed and heed Hawaii County Civil Defense alerts.
