The Hawaiian Volcano Observatory (HVO) report that over the past month at Kilauea volcano, the rates of seismicity varied but within a range observed over the past year. Sulfur dioxide emission rates have been low at the summit and below detection limits at Puʻu ʻŌʻō and the lower East Rift Zone. The water pond at the bottom of Halema'uma'u continues to slowly expand and deepen and its dimensions are approximately 100 meters (330 feet) by 200 meters (660 feet) and approximately 28 meters or 92 feet deep as of early March.

There have been around 9 deflation-inflation events over the past month, a similar amount to January. Since March 2019, HVO have recorded deformation at the summit of Kilauea, 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). Some amount of sulfur dioxide is being dissolved into the summit lake and work continues to try and quantify this process. The pond was last sampled by UAS in January and additional, regular sampling with UAS is planned.

During the month of February, deformation rates between Puʻu ʻŌʻō and Highway 130 have decreased slightly. HVO does not suggest any imminent change in volcanic hazard for this area. The south flank of Kilauea continues to creep seaward at elevated rates following the May 4, 2018 M6.9 earthquake near Kalapana.
“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.”

“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.”

Kilauea caldera captured from HVO's KWcam (C) U.S. Geological Survey
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. ... Lees alle

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. ...
