(BIVN) – The Kilauea Volcano eruption continues on Hawai’i Island, with all activities confined to the top of Halema’uma’u Crater in Hawai’i Volcanoes National Park.
The activity has changed little in recent days. Scientists noted small “seeps” along the perimeter of the lava lake, including one that produced a lava flow a short distance over the lower block.
From the USGS Hawaiian Volcano Observatory on Friday, November 19:
Summit Observations: Sulfur dioxide (SO2) emission rates remain high, with an emission rate for November 18, 2021 of approximately 3,800 tonnes per day. Summit inclinometers have generally recorded a generally neutral incline over the past day. Seismicity remains stable. The seismic activity remains below the background noise and the volcanic tremor has remained high since the start of the eruption.
Observations of the Halema’uma’u lava lake: Lava continues to emerge from a single vent in the western wall of Halema’uma’u Crater, while the eastern edge of the lake continues to advance over the lower exposed blocks of soil in the caldera. The western end of the lake showed a maximum elevation of about 804 meters (2,638 feet) above sea level by the HVO permanent laser range finder this morning, and a total increase of about 60 meters (197 feet) ) since the lava emerged on September 29. The webcams show splash and accumulated lava in the west vent, an area of active lava on the surface of the lava lake, and sporadic lava seeps along the cooler outer edges of the lake. The total eruption volume since the start of the eruption was estimated to be around 30 million cubic meters (7.8 billion gallons) on November 16.
The USGS HVO continues to note that no unusual activity has been observed in the Kīlauea East Rift area.
