| 説明 | (public domain, screen capture video from the V1 web camera on the northwestern rim of Kilauea Volcano's summit caldera)------------------------------------------------Mt. Kilauea is the world’s most active volcano. It sits atop the Hawaii Hotspot in the central Pacific Ocean and had a decades-long eruption from 1983 to 2018. Eruptive activity started up again in December 2020 and continued into 2025. Kilauea lavas are basaltic in composition, but the physical appearance of Kilauea’s output varies tremendously. Many of Kilauea’s eruptions occurred along its East Rift Zone, a fracture system extending ~eastward from the summit vent area. Seen here is lava erupting at the summit of Kilauea Volcano from 1:42 to 1:46, local time, on 20 March 2025. This is "episode 14", which started in the mid-morning of 19 March 2025 and ended in the afternoon of 20 March 2025. "Episode 1" of the current eruption series started on 23 December 2024.--------------------------------Info. from the Hawaiian Volcano Observatory (HVO) & United States Geological Survey (USGS):Episode 14 of the ongoing Halemaumau eruption ended at 1:49 PM Hawaiian Standard Time on March 20 when fountaining at the south vent stopped. Fountains from the north vent ceased 11 minutes earlier.Lava flows from this episode covered about 75% of the floor of Halemaumau within the southern part of Kaluapele (Kilauea caldera). Episode 14 lasted 28 hours and 23 minutes with the last 7 hours and 19 minutes consisting of fountains up to 600 feet (180 meters) high predominantly from the south vent.Deflationary tilt at the summit recorded about 6 microradians lost during this episode. Initial deflation was very rapid, but slowed at 7:46 AM Hawaiian Standard Time when north vent fountains dropped back into the cone and became intermittent. The end of the eruption was coincident with a rapid change from deflation to inflation at the summit and a decrease in seismic tremor intensity. Each episode of Halemaumau lava fountaining since December 23, 2024, has continued for 13 hours to 8 days and episodes have been separated by pauses in eruptive activity lasting less than 24 hours to 12 days.--------------------------------Locality: Halemaumau Crater, southwestern corner of Kilauea Crater (Kilauea Caldera), southeastern Hawaii, central Pacific Basin--------------------------------Info. at:en.wikipedia.org/wiki/Halemaʻumaʻu |
