Lava lake activity continues at Halema'uma'u, atop Kīlauea Volcano. A small stream of lava was flowing into a small pond northwest of the main lava lake, near the western vent. USGS photo by Mr. Patrick - 26.05.2022. - one click to enlarge
In Kilauea, lava eruption from the western vent in the active Halemaʻumaʻu lava lake and seeps on the crater floor have continued over the past 24 hours. The active lava lake has shown continued surface activity, although the level of the active lake has dropped 5 meters (16 feet) since yesterday afternoon. Lava seepage activity occurred along the eastern, northeast, northwest, western, and southern edges of the crater floor.
Flyby measurements on May 10, 2022 indicated that the crater floor had seen a total elevation of about 106 meters (348 feet) and that 77 million cubic meters (20 billion gallons) of lava had been effused since the start. of this eruption on September 29. , 2021.
Summit tiltmeters have recorded deflation over the past 24 hours. A sulfur dioxide emission rate of approximately 3,900 tonnes per day (t/d) was measured on May 31, 2022.
All recent lava activity has been confined to the crater, and current data indicates that this scenario is likely to continue. No significant changes were noted at the summit or in the East Rift Zone. The current volcanic alert level is Watch and the aviation color code remains orange.
A strong Strombolian activity is observed at the level of the craters of the summit of Etna. Thermal anomalies remain "very high" according to Mirova. The ash emission is in progress.
The height of the volcanic clouds is estimated at 4000 M above the summit, moving towards the South-South-West.
The aviation color code changed to red at 04:29Z, before being lowered to orange at 05:49Z, following the containment of volcanic ash in the summit area.

In the Reykjanes Peninsula, inflation in the area west of Þorbjörn has come down significantly over the past week. No rise in inflation has been measured on the Meteorological Bureau's GPS meters for three to four days.
Seismic activity has also decreased significantly and according to Lovísa Mjallar Guðmundsdóttir, nature conservation specialist at the Meteorological Office, the last magnitude 3 earthquake west of Þorbjörn was measured on May 29.
Civil Protection Uncertainty Level remains in effect.
From April 28 to May 28, the terrain rose 5.0 to 5.5 centimeters and was accompanied by significant seismic activity. In recent days, 150 to 300 earthquakes have been recorded there. Nearly 800 earthquakes were recorded per day at its peak. The Weather Bureau website says that in light of this, the flight color code for the area has been moved from yellow to green. However, the level of uncertainty in terms of civil security is still relevant.
In the past, activity has been periodic on the peninsula and so this could be a temporary outage.
According to Lovísa, it cannot be excluded that the activity increases again and occurs in cycles. There is still considerable activity throughout the Reykjanes Peninsula.
