KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN
Activity Summary: Kīlauea Volcano is not erupting. Monitoring data continue to show steady rates of seismicity and ground deformation, low rates of sulfur dioxide emission, and only minor geologic changes since the end of eruptive activity in September 2018. Water continues to pond at the bottom of Halema'uma'u inside the summit caldera.

Observations: Monitoring data have shown no significant changes in volcanic activity over the past week. Rates of earthquake activity or seismicity across the volcano remain largely steady. Sulfur dioxide emission rates are low at the summit and are below detection limits at Puʻu ʻŌʻō and the lower East Rift Zone. The pond at the bottom of Halema'uma'u, which began forming on July 25, 2019, continues to slowly expand and deepen.

Although not currently erupting, areas of persistently elevated ground temperatures and minor release of gases are still found in the vicinity of the 2018 lower East Rift Zone fissures. These include steam (water), very small amounts of hydrogen sulfide, and carbon dioxide. These conditions are expected to be long-term. Similar conditions following the 1955 eruption continued for years to decades.

Since early March 2019, GPS stations and tiltmeters at the Kīlauea summit have recorded deformation consistent with slow magma accumulation within the shallow portion of the Kīlauea summit magma system (1-2 km or approximately 1 mile below ground level). However, gas measurements have yet to indicate significant shallowing of magma. HVO continues to carefully monitor all data streams at the Kīlauea summit for important changes.

Further east, GPS stations and tiltmeters continue to show motions consistent with slowed refilling of the deep East Rift Zone magmatic reservoir in the broad region between Puʻu ʻŌʻō and Highway 130. Monitoring data do not suggest any imminent change in volcanic hazard for this area. In addition to motion along the East Rift Zone, the south flank of Kīlauea continues to creep seaward at elevated rates following the May 4, 2018 M6.9 earthquake near Kalapana. HVO continues to carefully monitor all data streams along the Kīlauea East Rift Zone and south flank for important changes.

Hazards: Hazards remain in the lower East Rift Zone eruption area and at the Kīlauea summit. Residents and visitors near the 2018 fissures, lava flows, and summit collapse area should heed Hawaii County Civil Defense and National Park warnings. Lava flows and features created by the 2018 eruption are primarily on private property and persons are asked to be respectful and not enter or park on private property.

The Hawaiian Volcano Observatory (HVO) continues to closely monitor geologic changes, seismicity, deformation, and gas emissions for any sign of increased activity at Kīlauea. HVO maintains visual surveillance of the volcano with web cameras and field visits. Additional messages and alert level changes will be issued as warranted by changing activity.

Background As of June 25, Kīlauea Volcano has been at NORMAL/GREEN. For definitions of USGS Volcano Alert Levels and Aviation Color Codes, see: https://volcanoes.usgs.gov/vhp/about_alerts.html. Kīlauea remains an active volcano, and it will erupt again. Although we expect clear signs prior to the next eruption, the time frame of warning may be short. Island of Hawaiʻi residents should be familiar with the long-term hazard map for Kīlauea Volcano (https://pubs.usgs.gov/mf/1992/2193/) and should stay informed about Kīlauea activity.

Halema‘uma‘u water pond on September 10

No major changes were observed at the water pond in Halema‘uma‘u during this morning's visit. The water surface continues to slowly rise, as shown by comparing the waterline against rocks in today's and yesterday's photos. USGS photo by M. Patrick, 09-10-2019.
Left: This photo was taken just a few minutes after the image above. With a slight shift in the direction steam wafted above the water and a different camera setting, variations in the color of the water surface became more obvious. USGS photo by M. Patrick, 09-10-2019. Right: This telephoto image shows the color variation in the eastern portion of the pond, with a sharp boundary between yellow and greenish-blue areas in the water.
