Kilauea volcano (Hawai'i): HVO monthly update

Over the past month, rates of seismicity were variable but within long term vales. 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. The pond has grown 95 meters by 194 meters (310 feet by 640 feet) and 25 meters (82 feet) deep. The pond has deepened by 2 meters (around 7 feet) over the month of January 2020.

8 deflation-inflation (DI) events occurred beneath the summit, which according to HVO, is slightly less than the prior month. Since early March 2019, GPS stations and tiltmeters at the Kilauea summit have recorded deformation consistent with slow magma accumulation within the shallow portion of the Kilauea summit magma system (1-2 km or approximately 1 mile below ground level). During January, deformation rates at Kilauea summit appeared to have decreased somewhat. Gas measurements show continuing low levels of sulfur dioxide, consistent with no significant shallowing of magma.

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. During January, deformation rates in this region appeared to have decreased somewhat. Monitoring data from HVO 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 Kilauea continues to creep seaward at elevated rates following the May 4, 2018 M6.9 earthquake near Kalapana.

Hazards: “Hazards remain in the lower East Rift Zone eruption area and at the Kilauea 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) note that the rates of seismicity over the month of December 2019 were variable but within long term vales. Sulfur dioxide emission rates were low at the summit and were below detection limits at Puʻu ʻŌʻō and the lower East Rift Zone. The pond at the bottom of Halema'uma'u crater, which began forming on July 25, 2019, continues to slowly expand and deepen. As of early January 2020, the dimensions of the pond are 84 meters by 190 meters (280 feet by 620 feet). Current depth is about 23 meters (75 feet). ... Lees alle

Kilauea caldera captured from HVO's KWcam (C) U.S. Geological Survey
The Hawaiian Volcano Observatory (HVO) report that their monitoring data have shown no significant changes in volcanic activity during November. Over the past month, about a dozen DI (Deflation-Inflation) events occurred beneath the summit. Over 1800 earthquakes were detected in the vicinity of the volcano, which is an increase of around 10% from last month. Rates of seismicity are relatively consistent throughout the month, although at the summit, episodic increased rates appear to be coincident with the inflated phase of the DI events. Sulfur dioxide emission rates are low at the summit and are below detection limits at Puʻu ʻOʻo 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, and the most recent measurements are 162 meters in the east-west direction and 73 meters in the north-south direction. ...
