Lava Now 0.2 Miles from Ocean

Activity Summary: Eruptive activity continues at Kīlauea Volcano’s summit and East Rift Zone. The 61G lava flow extending southeast of Puʻu ʻŌʻō towards the ocean remains active but poses no threat to nearby communities. As of yesterday, the flow tip was about ~370 m (0.2 miles) from the ocean. The lava lake at Halemaʻumaʻu Crater continues to circulate and intermittently spatter. Seismicity and deformation rates throughout the volcano remain at background levels.

Summit Observations: The lava lake within the Halemaʻumaʻu Overlook crater remains active. The depth to the lake was estimated at 26 m (85 ft) below the crater rim, measured on Sunday. Tiltmeters at Kīlauea’s summit recorded a slight inflationary tilt. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. The summit sulfur dioxide emission rate ranged from 3,700 to 7,300 metric tons/day.

Puʻu ʻŌʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater. There were no significant changes in seismicity over the past 24 hours. The tilt still recovering due to heavy rainfall over the weekend. The sulfur dioxide emission rate from all East Rift Zone vents on July 22 was about 500 metric tons/day.

Lava Flow Observations: The 61G lava flow extending southeast of Puʻu ʻŌʻō towards the coastal plain on Kīlauea’s south flank remains active. On Sunday, the flow tip was active and breakouts were active within a few hundred meters (yards) upslope. The flow was approximately ~240 m (0.15 miles) from the coastal emergency road and 370 m (0.2 miles) from the ocean; based on National Park personnel observations. Areas of incandescence remain visible in overnight webcam views of the active lava flow field, marking lava tube skylights and areas of active lava on the pali and along the flow as it extends towards the coast.
