“Summit Observations: Summit tilt fluctuated over the past day, with deflationary tilt switching to inflationary tilt yesterday around 4pm. The lava lake level fluctuated with these tilt changes as well as with changes in spattering activity. This morning the lake was roughly 65 m (210 ft) below the Overlook crater rim. Summit sulfur dioxide emission rates ranged from 780 to 6000 metric tons per day during the 2-week period ending October 13.

Puʻu ʻŌʻō Observations: Webcams show no significant change in eruptive activity at Puʻu ʻŌʻō. There was no significant change in tilt over the past day. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons per day when measurements were last possible on October 2, 2015. Seismic activity has returned to background levels.”USGS Hawaiian Volcano Observatory on Oct. 18, 2015

“The seismicity rate is elevated above background, though at a lower weekly rate than reported in mid- to late-summer. Earthquakes occurred beneath Mauna Loa’s upper Southwest Rift Zone at depths less than 13 km (8 miles). Deformation data are still consistent with inflation of magma reservoirs beneath Mauna Loa’s summit and upper Southwest Rift Zone.”USGS Hawaiian Volcano Observatory on Oct. 15, 2015

“We are sorry for any inconvenience this may cause for park visitors and the community who enjoy Nāmakanipaio,” said Park Superintendent Cindy Orlando. “Safety is our number one priority in the park, and we do not want anyone to get hurt.”National Park Service
