![]() ![]() Mayon | 14 June-20 June 2023 | New Activity / Unrest Cite this Report Source: Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG, also known as CVGHM) The volcano Alert Level remained at 2 (on a scale of 1-4) and the public was reminded not to approach the crater within a radius of 1.5 km. During 2023 white emissions generally rose 20-150 m above the crater rim and seismicity was generally dominated by 1-2 daily shallow volcanic earthquakes. White steam-and-gas emissions of variable densities rose as high as 500 m and drifted N, W, and S during 14-20 June. The emissions were followed by a period of continuous tremor during 1835-2100. In a press release PVMBG reported increased emissions at Lokon-Empung on 13 June with dense white plumes rising 400 m above the rim of Tompaluan Crater and drifting S a total of 12 earthquakes indicating emissions were recorded by the seismic network. Lokon-Empung | 14 June-20 June 2023 | New Activity / Unrest Cite this Report Source: US Geological Survey Hawaiian Volcano Observatory (HVO) Seismic activity remained low and on 20 June HVO reported that the eruption had paused. Around 1600 on 19 June activity rapidly declined, shown by a drop in the SW lake surface, decreased seismicity, and a transition to inflationary tilt from the deflationary trend of the previous two days. This activity continued into 19 June as the crater floor continued to rise, circulation in central basin slowed, and flows from the base of the SW wall cone changed paths. The central basin level has been dropping relative to the rising crater floor (due to lava accumulation underneath), allowing several flows from the SW lava lake to cascade into the basin.īy 16 June, renewed activity on the SW wall was producing vigorous fountaining to at least 10 m high with some higher spatters, with lava flowing into the SW lake. At 0800 on 15 June the top of the SW wall cone collapsed, leading to nearly constant spattering from the top vent and a change in activity from the base vent. ![]() Additionally, lava circulation continued within the central basin. The surface of the SW lava lake slowly rose about 0.5 m per day during 13-15 June. Other eruptive vents within the SW lava lake (previously dome fountains) had ceased by 13 June. Lava flows from vents at the base and top of a cone on the SW wall of Halema'uma'u entered the lava lake in the far SW portion of the crater intermittent spattering from the cone was visible at night. Activity was characterized by effusion primarily from the vent on the SW wall of the crater, circulation within the crater lakes, slow rise of the crater floor, eruptive tremor, and elevated sulfur dioxide levels (4,500-6,300 tonnes per day). HVO reported that the eruption on the floor of Kilauea’s Halema'uma'u Crater continued during 14-20 June.
