The Hawaiian Volcano Observatory (HVO) reported that the volcano's summit water lake has continued to rise since 25 July last year when water was first spotted at the bottom of Halema‘uma‘u pit crater inside the summit caldera.

Over the past year, the summit water lake has grown to more than 270 m (885 ft) long and 131 m (430 ft) wide, covering a surface area over 2.5 hectares (6 acres). The lake is over 40 m (130 ft) deep and contains a volume of approximately 480,000 cubic meters.
On 2 August 2019, only a small green pond approx. 6 ft (2 m) deep could be seen.
The image taken on 21 July 2020 shows a lake more than 130 ft (40 m) deep with shades of tan to brown and a sharp color boundary often cutting across the lake.
The photo taken on 28 July 2020 shows vibrant lake colors with a zone of aquamarine water in the west end. These greenish zones tend to be slightly hotter and appear to be zones of water influx.
The maximum temperatures on the lake surface at this time were measured at about 82 degrees Celsius (180 degrees Fahrenheit).
Surface water at the summit presents a potential future hazard at the summit: Magma interacting with near-surface water can, in some circumstances, trigger violent steam-blast explosions.

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. ... read all

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. ... read all

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). ... read all

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. ... read all
